# Simple Markdown Viewer
A tiny Node.js app that serves **all** markdown (`.md`) files in the workspace with a two‑pane UI:
- **Left pane** – a collapsible directory tree.
- **Right pane** – the selected markdown rendered to HTML.
## Features
- Auto‑detects directories and markdown files.
- Click a folder to expand/collapse.
- Click a file to view it instantly.
- Runs on **port 8100** (http://localhost:8100).
- No build step – just `npm install` and `npm start`.
## Install & Run
```bash
cd /viewer
npm install # installs express & markdown-it
npm start
```
Open your browser at `http://localhost:8100`.
The server serves the whole workspace (the parent of the `viewer` folder) as the markdown root, so you can browse any `.md` file, e.g. `Projects/POS/ICP.md`.
## Files
- `server.js` – Express backend with two APIs (`/api/tree` and `/api/md`).
- `public/` – static HTML/CSS/JS for the UI.
- `package.json` – npm metadata.
Enjoy!

Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
In addition to negotiator, it allows:
- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
as well as `('text/html', 'application/json')`.
- Allows type shorthands such as `json`.
- Returns `false` when no types match
- Treats non-existent headers as `*`
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```sh
$ npm install accepts
```
## API
```js
var accepts = require('accepts')
```
### accepts(req)
Create a new `Accepts` object for the given `req`.
#### .charset(charsets)
Return the first accepted charset. If nothing in `charsets` is accepted,
then `false` is returned.
#### .charsets()
Return the charsets that the request accepts, in the order of the client's
preference (most preferred first).
#### .encoding(encodings)
Return the first accepted encoding. If nothing in `encodings` is accepted,
then `false` is returned.
#### .encodings()
Return the encodings that the request accepts, in the order of the client's
preference (most preferred first).
#### .language(languages)
Return the first accepted language. If nothing in `languages` is accepted,
then `false` is returned.
#### .languages()
Return the languages that the request accepts, in the order of the client's
preference (most preferred first).
#### .type(types)
Return the first accepted type (and it is returned as the same text as what
appears in the `types` array). If nothing in `types` is accepted, then `false`
is returned.
The `types` array can contain full MIME types or file extensions. Any value
that is not a full MIME types is passed to `require('mime-types').lookup`.
#### .types()
Return the types that the request accepts, in the order of the client's
preference (most preferred first).
## Examples
### Simple type negotiation
This simple example shows how to use `accepts` to return a different typed
respond body based on what the client wants to accept. The server lists it's
preferences in order and will get back the best match between the client and
server.
```js
var accepts = require('accepts')
var http = require('http')
function app (req, res) {
var accept = accepts(req)
// the order of this list is significant; should be server preferred order
switch (accept.type(['json', 'html'])) {
case 'json':
res.setHeader('Content-Type', 'application/json')
res.write('{"hello":"world!"}')
break
case 'html':
res.setHeader('Content-Type', 'text/html')
res.write('<b>hello, world!</b>')
break
default:
// the fallback is text/plain, so no need to specify it above
res.setHeader('Content-Type', 'text/plain')
res.write('hello, world!')
break
}
res.end()
}
http.createServer(app).listen(3000)
```
You can test this out with the cURL program:
```sh
curl -I -H'Accept: text/html' http://localhost:3000/
```

A. HISTORY OF THE SOFTWARE
==========================
Python was created in the early 1990s by Guido van Rossum at Stichting
Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
as a successor of a language called ABC. Guido remains Python's
principal author, although it includes many contributions from others.
In 1995, Guido continued his work on Python at the Corporation for
National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
in Reston, Virginia where he released several versions of the
software.
In May 2000, Guido and the Python core development team moved to
BeOpen.com to form the BeOpen PythonLabs team. In October of the same
year, the PythonLabs team moved to Digital Creations, which became
Zope Corporation. In 2001, the Python Software Foundation (PSF, see
https://www.python.org/psf/) was formed, a non-profit organization
created specifically to own Python-related Intellectual Property.
Zope Corporation was a sponsoring member of the PSF.
All Python releases are Open Source (see http://www.opensource.org for
the Open Source Definition). Historically, most, but not all, Python
releases have also been GPL-compatible; the table below summarizes
the various releases.
Release Derived Year Owner GPL-
from compatible? (1)
0.9.0 thru 1.2 1991-1995 CWI yes
1.3 thru 1.5.2 1.2 1995-1999 CNRI yes
1.6 1.5.2 2000 CNRI no
2.0 1.6 2000 BeOpen.com no
1.6.1 1.6 2001 CNRI yes (2)
2.1 2.0+1.6.1 2001 PSF no
2.0.1 2.0+1.6.1 2001 PSF yes
2.1.1 2.1+2.0.1 2001 PSF yes
2.1.2 2.1.1 2002 PSF yes
2.1.3 2.1.2 2002 PSF yes
2.2 and above 2.1.1 2001-now PSF yes
Footnotes:
(1) GPL-compatible doesn't mean that we're distributing Python under
the GPL. All Python licenses, unlike the GPL, let you distribute
a modified version without making your changes open source. The
GPL-compatible licenses make it possible to combine Python with
other software that is released under the GPL; the others don't.
(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
because its license has a choice of law clause. According to
CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
is "not incompatible" with the GPL.
Thanks to the many outside volunteers who have worked under Guido's
direction to make these releases possible.

argparse
========
[![Build Status](https://secure.travis-ci.org/nodeca/argparse.svg?branch=master)](http://travis-ci.org/nodeca/argparse)
[![NPM version](https://img.shields.io/npm/v/argparse.svg)](https://www.npmjs.org/package/argparse)
CLI arguments parser for node.js, with [sub-commands](https://docs.python.org/3.9/library/argparse.html#sub-commands) support. Port of python's [argparse](http://docs.python.org/dev/library/argparse.html) (version [3.9.0](https://github.com/python/cpython/blob/v3.9.0rc1/Lib/argparse.py)).
**Difference with original.**
- JS has no keyword arguments support.
- Pass options instead: `new ArgumentParser({ description: 'example', add_help: true })`.
- JS has no python's types `int`, `float`, ...
- Use string-typed names: `.add_argument('-b', { type: 'int', help: 'help' })`.
- `%r` format specifier uses `require('util').inspect()`.
More details in [doc](./doc).
Example
-------
`test.js` file:
```javascript
#!/usr/bin/env node
'use strict';
const { ArgumentParser } = require('argparse');
const { version } = require('./package.json');
const parser = new ArgumentParser({
description: 'Argparse example'
});
parser.add_argument('-v', '--version', { action: 'version', version });
parser.add_argument('-f', '--foo', { help: 'foo bar' });
parser.add_argument('-b', '--bar', { help: 'bar foo' });
parser.add_argument('--baz', { help: 'baz bar' });
console.dir(parser.parse_args());
```
Display help:
```
$ ./test.js -h
usage: test.js [-h] [-v] [-f FOO] [-b BAR] [--baz BAZ]
Argparse example
optional arguments:
-h, --help show this help message and exit
-v, --version show program's version number and exit
-f FOO, --foo FOO foo bar
-b BAR, --bar BAR bar foo
--baz BAZ baz bar
```
Parse arguments:
```
$ ./test.js -f=3 --bar=4 --baz 5
{ foo: '3', bar: '4', baz: '5' }
```
API docs
--------
Since this is a port with minimal divergence, there's no separate documentation.
Use original one instead, with notes about difference.

/*
* Object for wrapping/filling text. The public interface consists of
* the wrap() and fill() methods; the other methods are just there for
* subclasses to override in order to tweak the default behaviour.
* If you want to completely replace the main wrapping algorithm,
* you'll probably have to override _wrap_chunks().
*
* Several instance attributes control various aspects of wrapping:
* width (default: 70)
* the maximum width of wrapped lines (unless break_long_words
* is false)
* initial_indent (default: "")
* string that will be prepended to the first line of wrapped
* output. Counts towards the line's width.
* subsequent_indent (default: "")
* string that will be prepended to all lines save the first
* of wrapped output; also counts towards each line's width.
* expand_tabs (default: true)
* Expand tabs in input text to spaces before further processing.
* Each tab will become 0 .. 'tabsize' spaces, depending on its position
* in its line. If false, each tab is treated as a single character.
* tabsize (default: 8)
* Expand tabs in input text to 0 .. 'tabsize' spaces, unless
* 'expand_tabs' is false.
* replace_whitespace (default: true)
* Replace all whitespace characters in the input text by spaces
* after tab expansion. Note that if expand_tabs is false and
* replace_whitespace is true, every tab will be converted to a
* single space!
* fix_sentence_endings (default: false)
* Ensure that sentence-ending punctuation is always followed
* by two spaces. Off by default because the algorithm is
* (unavoidably) imperfect.
* break_long_words (default: true)
* Break words longer than 'width'. If false, those words will not
* be broken, and some lines might be longer than 'width'.
* break_on_hyphens (default: true)
* Allow breaking hyphenated words. If true, wrapping will occur
* preferably on whitespaces and right after hyphens part of
* compound words.
* drop_whitespace (default: true)
* Drop leading and trailing whitespace from lines.
* max_lines (default: None)
* Truncate wrapped lines.
* placeholder (default: ' [...]')
* Append to the last line of truncated text.

Node.js body parsing middleware.
Parse incoming request bodies in a middleware before your handlers, available
under the `req.body` property.
**Note** As `req.body`'s shape is based on user-controlled input, all
properties and values in this object are untrusted and should be validated
before trusting. For example, `req.body.foo.toString()` may fail in multiple
ways, for example the `foo` property may not be there or may not be a string,
and `toString` may not be a function and instead a string or other user input.
[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/).
_This does not handle multipart bodies_, due to their complex and typically
large nature. For multipart bodies, you may be interested in the following
modules:
* [busboy](https://www.npmjs.org/package/busboy#readme) and
[connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
* [multiparty](https://www.npmjs.org/package/multiparty#readme) and
[connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
* [formidable](https://www.npmjs.org/package/formidable#readme)
* [multer](https://www.npmjs.org/package/multer#readme)
This module provides the following parsers:
* [JSON body parser](#bodyparserjsonoptions)
* [Raw body parser](#bodyparserrawoptions)
* [Text body parser](#bodyparsertextoptions)
* [URL-encoded form body parser](#bodyparserurlencodedoptions)
Other body parsers you might be interested in:
- [body](https://www.npmjs.org/package/body#readme)
- [co-body](https://www.npmjs.org/package/co-body#readme)
## Installation
```sh
$ npm install body-parser
```
## API
```js
var bodyParser = require('body-parser')
```
The `bodyParser` object exposes various factories to create middlewares. All
middlewares will populate the `req.body` property with the parsed body when
the `Content-Type` request header matches the `type` option, or an empty
object (`{}`) if there was no body to parse, the `Content-Type` was not matched,
or an error occurred.
The various errors returned by this module are described in the
[errors section](#errors).
### bodyParser.json([options])
Returns middleware that only parses `json` and only looks at requests where
the `Content-Type` header matches the `type` option. This parser accepts any
Unicode encoding of the body and supports automatic inflation of `gzip` and
`deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`).
#### Options
The `json` function takes an optional `options` object that may contain any of
the following keys:
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### reviver
The `reviver` option is passed directly to `JSON.parse` as the second
argument. You can find more information on this argument
[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
##### strict
When set to `true`, will only accept arrays and objects; when `false` will
accept anything `JSON.parse` accepts. Defaults to `true`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not a
function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
be an extension name (like `json`), a mime type (like `application/json`), or
a mime type with a wildcard (like `*/*` or `*/json`). If a function, the `type`
option is called as `fn(req)` and the request is parsed if it returns a truthy
value. Defaults to `application/json`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.raw([options])
Returns middleware that parses all bodies as a `Buffer` and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser supports automatic inflation of `gzip` and `deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This will be a `Buffer` object
of the body.
#### Options
The `raw` function takes an optional `options` object that may contain any of
the following keys:
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function.
If not a function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this
can be an extension name (like `bin`), a mime type (like
`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
`application/*`). If a function, the `type` option is called as `fn(req)`
and the request is parsed if it returns a truthy value. Defaults to
`application/octet-stream`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.text([options])
Returns middleware that parses all bodies as a string and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser supports automatic inflation of `gzip` and `deflate` encodings.
A new `body` string containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This will be a string of the
body.
#### Options
The `text` function takes an optional `options` object that may contain any of
the following keys:
##### defaultCharset
Specify the default character set for the text content if the charset is not
specified in the `Content-Type` header of the request. Defaults to `utf-8`.
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not
a function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
be an extension name (like `txt`), a mime type (like `text/plain`), or a mime
type with a wildcard (like `*/*` or `text/*`). If a function, the `type`
option is called as `fn(req)` and the request is parsed if it returns a
truthy value. Defaults to `text/plain`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
### bodyParser.urlencoded([options])
Returns middleware that only parses `urlencoded` bodies and only looks at
requests where the `Content-Type` header matches the `type` option. This
parser accepts only UTF-8 encoding of the body and supports automatic
inflation of `gzip` and `deflate` encodings.
A new `body` object containing the parsed data is populated on the `request`
object after the middleware (i.e. `req.body`). This object will contain
key-value pairs, where the value can be a string or array (when `extended` is
`false`), or any type (when `extended` is `true`).
#### Options
The `urlencoded` function takes an optional `options` object that may contain
any of the following keys:
##### extended
The `extended` option allows to choose between parsing the URL-encoded data
with the `querystring` library (when `false`) or the `qs` library (when
`true`). The "extended" syntax allows for rich objects and arrays to be
encoded into the URL-encoded format, allowing for a JSON-like experience
with URL-encoded. For more information, please
[see the qs library](https://www.npmjs.org/package/qs#readme).
Defaults to `true`, but using the default has been deprecated. Please
research into the difference between `qs` and `querystring` and choose the
appropriate setting.
##### inflate
When set to `true`, then deflated (compressed) bodies will be inflated; when
`false`, deflated bodies are rejected. Defaults to `true`.
##### limit
Controls the maximum request body size. If this is a number, then the value
specifies the number of bytes; if it is a string, the value is passed to the
[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
to `'100kb'`.
##### parameterLimit
The `parameterLimit` option controls the maximum number of parameters that
are allowed in the URL-encoded data. If a request contains more parameters
than this value, a 413 will be returned to the client. Defaults to `1000`.
##### type
The `type` option is used to determine what media type the middleware will
parse. This option can be a string, array of strings, or a function. If not
a function, `type` option is passed directly to the
[type-is](https://www.npmjs.org/package/type-is#readme) library and this can
be an extension name (like `urlencoded`), a mime type (like
`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
`*/x-www-form-urlencoded`). If a function, the `type` option is called as
`fn(req)` and the request is parsed if it returns a truthy value. Defaults
to `application/x-www-form-urlencoded`.
##### verify
The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
where `buf` is a `Buffer` of the raw request body and `encoding` is the
encoding of the request. The parsing can be aborted by throwing an error.
#### depth
The `depth` option is used to configure the maximum depth of the `qs` library when `extended` is `true`. This allows you to limit the amount of keys that are parsed and can be useful to prevent certain types of abuse. Defaults to `32`. It is recommended to keep this value as low as possible.
## Errors
The middlewares provided by this module create errors using the
[`http-errors` module](https://www.npmjs.com/package/http-errors). The errors
will typically have a `status`/`statusCode` property that contains the suggested
HTTP response code, an `expose` property to determine if the `message` property
should be displayed to the client, a `type` property to determine the type of
error without matching against the `message`, and a `body` property containing
the read body, if available.
The following are the common errors created, though any error can come through
for various reasons.
### content encoding unsupported
This error will occur when the request had a `Content-Encoding` header that
contained an encoding but the "inflation" option was set to `false`. The
`status` property is set to `415`, the `type` property is set to
`'encoding.unsupported'`, and the `charset` property will be set to the
encoding that is unsupported.
### entity parse failed
This error will occur when the request contained an entity that could not be
parsed by the middleware. The `status` property is set to `400`, the `type`
property is set to `'entity.parse.failed'`, and the `body` property is set to
the entity value that failed parsing.
### entity verify failed
This error will occur when the request contained an entity that could not be
failed verification by the defined `verify` option. The `status` property is
set to `403`, the `type` property is set to `'entity.verify.failed'`, and the
`body` property is set to the entity value that failed verification.
### request aborted
This error will occur when the request is aborted by the client before reading
the body has finished. The `received` property will be set to the number of
bytes received before the request was aborted and the `expected` property is
set to the number of expected bytes. The `status` property is set to `400`
and `type` property is set to `'request.aborted'`.
### request entity too large
This error will occur when the request body's size is larger than the "limit"
option. The `limit` property will be set to the byte limit and the `length`
property will be set to the request body's length. The `status` property is
set to `413` and the `type` property is set to `'entity.too.large'`.
### request size did not match content length
This error will occur when the request's length did not match the length from
the `Content-Length` header. This typically occurs when the request is malformed,
typically when the `Content-Length` header was calculated based on characters
instead of bytes. The `status` property is set to `400` and the `type` property
is set to `'request.size.invalid'`.
### stream encoding should not be set
This error will occur when something called the `req.setEncoding` method prior
to this middleware. This module operates directly on bytes only and you cannot
call `req.setEncoding` when using this module. The `status` property is set to
`500` and the `type` property is set to `'stream.encoding.set'`.
### stream is not readable
This error will occur when the request is no longer readable when this middleware
attempts to read it. This typically means something other than a middleware from
this module read the request body already and the middleware was also configured to
read the same request. The `status` property is set to `500` and the `type`
property is set to `'stream.not.readable'`.
### too many parameters
This error will occur when the content of the request exceeds the configured
`parameterLimit` for the `urlencoded` parser. The `status` property is set to
`413` and the `type` property is set to `'parameters.too.many'`.
### unsupported charset "BOGUS"
This error will occur when the request had a charset parameter in the
`Content-Type` header, but the `iconv-lite` module does not support it OR the
parser does not support it. The charset is contained in the message as well
as in the `charset` property. The `status` property is set to `415`, the
`type` property is set to `'charset.unsupported'`, and the `charset` property
is set to the charset that is unsupported.
### unsupported content encoding "bogus"
This error will occur when the request had a `Content-Encoding` header that
contained an unsupported encoding. The encoding is contained in the message
as well as in the `encoding` property. The `status` property is set to `415`,
the `type` property is set to `'encoding.unsupported'`, and the `encoding`
property is set to the encoding that is unsupported.
### The input exceeded the depth
This error occurs when using `bodyParser.urlencoded` with the `extended` property set to `true` and the input exceeds the configured `depth` option. The `status` property is set to `400`. It is recommended to review the `depth` option and evaluate if it requires a higher value. When the `depth` option is set to `32` (default value), the error will not be thrown.
## Examples
### Express/Connect top-level generic
This example demonstrates adding a generic JSON and URL-encoded parser as a
top-level middleware, which will parse the bodies of all incoming requests.
This is the simplest setup.
```js
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }))
// parse application/json
app.use(bodyParser.json())
app.use(function (req, res) {
res.setHeader('Content-Type', 'text/plain')
res.write('you posted:\n')
res.end(JSON.stringify(req.body, null, 2))
})
```
### Express route-specific
This example demonstrates adding body parsers specifically to the routes that
need them. In general, this is the most recommended way to use body-parser with
Express.
```js
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// create application/json parser
var jsonParser = bodyParser.json()
// create application/x-www-form-urlencoded parser
var urlencodedParser = bodyParser.urlencoded({ extended: false })
// POST /login gets urlencoded bodies
app.post('/login', urlencodedParser, function (req, res) {
res.send('welcome, ' + req.body.username)
})
// POST /api/users gets JSON bodies
app.post('/api/users', jsonParser, function (req, res) {
// create user in req.body
})
```
### Change accepted type for parsers
All the parsers accept a `type` option which allows you to change the
`Content-Type` that the middleware will parse.
```js
var express = require('express')
var bodyParser = require('body-parser')
var app = express()
// parse various different custom JSON types as JSON
app.use(bodyParser.json({ type: 'application/*+json' }))
// parse some custom thing into a Buffer
app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
// parse an HTML body into a string
app.use(bodyParser.text({ type: 'text/html' }))
```

## Threat Model for qs (querystring parsing library)
### 1. Library Overview
- **Library Name:** qs
- **Brief Description:** A JavaScript library for parsing and stringifying URL query strings, supporting nested objects and arrays. It is widely used in Node.js and web applications for processing query parameters[2][6][8].
- **Key Public APIs/Functions:** `qs.parse()`, `qs.stringify()`
### 2. Define Scope
This threat model focuses on the core parsing and stringifying functionality, specifically the handling of nested objects and arrays, option validation, and cycle management in stringification.
### 3. Conceptual System Diagram
```
Caller Application → qs.parse(input, options) → Parsing Engine → Output Object
│
└→ Options Handling
Caller Application → qs.stringify(obj, options) → Stringifying Engine → Output String
│
└→ Options Handling
└→ Cycle Tracking
```
**Trust Boundaries:**
- **Input string (parse):** May come from untrusted sources (e.g., user input, network requests)
- **Input object (stringify):** May contain cycles, which can lead to infinite loops during stringification
- **Options:** Provided by the caller
- **Cycle Tracking:** Used only during stringification to detect and handle circular references
### 4. Identify Assets
- **Integrity of parsed output:** Prevent malicious manipulation of the output object structure, especially ensuring builtins/globals are not modified as a result of parse[3][4][8].
- **Confidentiality of processed data:** Avoid leaking sensitive information through errors or output.
- **Availability/performance for host application:** Prevent crashes or resource exhaustion in the consuming application.
- **Security of host application:** Prevent the library from being a vector for attacks (e.g., prototype pollution, DoS).
- **Reputation of library:** Maintain trust by avoiding supply chain attacks and vulnerabilities[1].
### 5. Identify Threats
| Component / API / Interaction | S | T | R | I | D | E |
|---------------------------------------|----|----|----|----|----|----|
| Public API Call (`parse`) | – | ✓ | – | ✓ | ✓ | ✓ |
| Public API Call (`stringify`) | – | ✓ | – | ✓ | ✓ | – |
| Options Handling | ✓ | ✓ | – | ✓ | – | ✓ |
| Dependency Interaction | – | – | – | – | ✓ | – |
**Key Threats:**
- **Tampering:** Malicious input can, if not prevented, alter parsed output (e.g., prototype pollution via `__proto__`, modification of builtins/globals)[3][4][8].
- **Information Disclosure:** Error messages may expose internal details or sensitive data.
- **Denial of Service:** Large or malformed input can exhaust memory or CPU.
- **Elevation of Privilege:** Prototype pollution can lead to unintended privilege escalation in the host application[3][4][8].
### 6. Mitigation/Countermeasures
| Threat Identified | Proposed Mitigation |
|---------------------------------------------------|---------------------|
| Tampering (malicious input, prototype pollution) | Strict input validation; keep `allowPrototypes: false` by default; use `plainObjects` for output; ensure builtins/globals are never modified by parse[4][8]. |
| Information Disclosure (error messages) | Generic error messages without stack traces or internal paths. |
| Denial of Service (memory/CPU exhaustion) | Enforce `arrayLimit` and `parameterLimit` with safe defaults; enable `throwOnLimitExceeded`; limit nesting depth[7]. |
| Elevation of Privilege (prototype pollution) | Keep `allowPrototypes: false`; validate options against allowlist; use `plainObjects` to avoid prototype pollution[4][8]. |
### 7. Risk Ranking
- **High:** Denial of Service via array parsing or malformed input (historical vulnerability)
- **Medium:** Prototype pollution via options or input (if `allowPrototypes` enabled)
- **Low:** Information disclosure in errors
### 8. Next Steps & Review
1. **Audit option validation logic.**
2. **Add depth limiting to nested parsing and stringification.**
3. **Implement fuzz testing for parser and stringifier edge cases.**
4. **Regularly review dependencies for vulnerabilities.**
5. **Keep documentation and threat model up to date.**
6. **Ensure builtins/globals are never modified as a result of parse.**
7. **Support round-trip consistency between parse and stringify as a non-security goal, with the right options[5][9].**

[![npm badge][npm-badge-png]][package-url]
A querystring parsing and stringifying library with some added security.
Lead Maintainer: [Jordan Harband](https://github.com/ljharb)
The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
## Usage
```javascript
var qs = require('qs');
var assert = require('assert');
var obj = qs.parse('a=c');
assert.deepEqual(obj, { a: 'c' });
var str = qs.stringify(obj);
assert.equal(str, 'a=c');
```
### Parsing Objects
[](#preventEval)
```javascript
qs.parse(string, [options]);
```
**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
For example, the string `'foo[bar]=baz'` converts to:
```javascript
assert.deepEqual(qs.parse('foo[bar]=baz'), {
foo: {
bar: 'baz'
}
});
```
When using the `plainObjects` option the parsed value is returned as a null object, created via `{ __proto__: null }` and as such you should be aware that prototype methods will not exist on it and a user may set those names to whatever value they like:
```javascript
var nullObject = qs.parse('a[hasOwnProperty]=b', { plainObjects: true });
assert.deepEqual(nullObject, { a: { hasOwnProperty: 'b' } });
```
By default parameters that would overwrite properties on the object prototype are ignored, if you wish to keep the data from those fields either use `plainObjects` as mentioned above, or set `allowPrototypes` to `true` which will allow user input to overwrite those properties.
*WARNING* It is generally a bad idea to enable this option as it can cause problems when attempting to use the properties that have been overwritten.
Always be careful with this option.
```javascript
var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true });
assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } });
```
URI encoded strings work too:
```javascript
assert.deepEqual(qs.parse('a%5Bb%5D=c'), {
a: { b: 'c' }
});
```
You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
```javascript
assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), {
foo: {
bar: {
baz: 'foobarbaz'
}
}
});
```
By default, when nesting objects **qs** will only parse up to 5 children deep.
This means if you attempt to parse a string like `'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
```javascript
var expected = {
a: {
b: {
c: {
d: {
e: {
f: {
'[g][h][i]': 'j'
}
}
}
}
}
}
};
var string = 'a[b][c][d][e][f][g][h][i]=j';
assert.deepEqual(qs.parse(string), expected);
```
This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`:
```javascript
var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } });
```
You can configure **qs** to throw an error when parsing nested input beyond this depth using the `strictDepth` option (defaulted to false):
```javascript
try {
qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1, strictDepth: true });
} catch (err) {
assert(err instanceof RangeError);
assert.strictEqual(err.message, 'Input depth exceeded depth option of 1 and strictDepth is true');
}
```
The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number. The strictDepth option adds a layer of protection by throwing an error when the limit is exceeded, allowing you to catch and handle such cases.
For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
```javascript
var limited = qs.parse('a=b&c=d', { parameterLimit: 1 });
assert.deepEqual(limited, { a: 'b' });
```
If you want an error to be thrown whenever the a limit is exceeded (eg, `parameterLimit`, `arrayLimit`), set the `throwOnLimitExceeded` option to `true`. This option will generate a descriptive error if the query string exceeds a configured limit.
```javascript
try {
qs.parse('a=1&b=2&c=3&d=4', { parameterLimit: 3, throwOnLimitExceeded: true });
} catch (err) {
assert(err instanceof Error);
assert.strictEqual(err.message, 'Parameter limit exceeded. Only 3 parameters allowed.');
}
```
When `throwOnLimitExceeded` is set to `false` (default), **qs** will parse up to the specified `parameterLimit` and ignore the rest without throwing an error.
To bypass the leading question mark, use `ignoreQueryPrefix`:
```javascript
var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true });
assert.deepEqual(prefixed, { a: 'b', c: 'd' });
```
An optional delimiter can also be passed:
```javascript
var delimited = qs.parse('a=b;c=d', { delimiter: ';' });
assert.deepEqual(delimited, { a: 'b', c: 'd' });
```
Delimiters can be a regular expression too:
```javascript
var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' });
```
Option `allowDots` can be used to enable dot notation:
```javascript
var withDots = qs.parse('a.b=c', { allowDots: true });
assert.deepEqual(withDots, { a: { b: 'c' } });
```
Option `decodeDotInKeys` can be used to decode dots in keys
Note: it implies `allowDots`, so `parse` will error if you set `decodeDotInKeys` to `true`, and `allowDots` to `false`.
```javascript
var withDots = qs.parse('name%252Eobj.first=John&name%252Eobj.last=Doe', { decodeDotInKeys: true });
assert.deepEqual(withDots, { 'name.obj': { first: 'John', last: 'Doe' }});
```
Option `allowEmptyArrays` can be used to allowing empty array values in object
```javascript
var withEmptyArrays = qs.parse('foo[]&bar=baz', { allowEmptyArrays: true });
assert.deepEqual(withEmptyArrays, { foo: [], bar: 'baz' });
```
Option `duplicates` can be used to change the behavior when duplicate keys are encountered
```javascript
assert.deepEqual(qs.parse('foo=bar&foo=baz'), { foo: ['bar', 'baz'] });
assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'combine' }), { foo: ['bar', 'baz'] });
assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'first' }), { foo: 'bar' });
assert.deepEqual(qs.parse('foo=bar&foo=baz', { duplicates: 'last' }), { foo: 'baz' });
```
Note that keys with bracket notation (`[]`) always combine into arrays, regardless of the `duplicates` setting:
```javascript
assert.deepEqual(qs.parse('a=1&a=2&b[]=1&b[]=2', { duplicates: 'last' }), { a: '2', b: ['1', '2'] });
```
If you have to deal with legacy browsers or services, there's also support for decoding percent-encoded octets as iso-8859-1:
```javascript
var oldCharset = qs.parse('a=%A7', { charset: 'iso-8859-1' });
assert.deepEqual(oldCharset, { a: '§' });
```
Some services add an initial `utf8=✓` value to forms so that old Internet Explorer versions are more likely to submit the form as utf-8.
Additionally, the server can check the value against wrong encodings of the checkmark character and detect that a query string or `application/x-www-form-urlencoded` body was *not* sent as utf-8, eg. if the form had an `accept-charset` parameter or the containing page had a different character set.
**qs** supports this mechanism via the `charsetSentinel` option.
If specified, the `utf8` parameter will be omitted from the returned object.
It will be used to switch to `iso-8859-1`/`utf-8` mode depending on how the checkmark is encoded.
**Important**: When you specify both the `charset` option and the `charsetSentinel` option, the `charset` will be overridden when the request contains a `utf8` parameter from which the actual charset can be deduced.
In that sense the `charset` will behave as the default charset rather than the authoritative charset.
```javascript
var detectedAsUtf8 = qs.parse('utf8=%E2%9C%93&a=%C3%B8', {
charset: 'iso-8859-1',
charsetSentinel: true
});
assert.deepEqual(detectedAsUtf8, { a: 'ø' });
// Browsers encode the checkmark as &#10003; when submitting as iso-8859-1:
var detectedAsIso8859_1 = qs.parse('utf8=%26%2310003%3B&a=%F8', {
charset: 'utf-8',
charsetSentinel: true
});
assert.deepEqual(detectedAsIso8859_1, { a: 'ø' });
```
If you want to decode the `&#...;` syntax to the actual character, you can specify the `interpretNumericEntities` option as well:
```javascript
var detectedAsIso8859_1 = qs.parse('a=%26%239786%3B', {
charset: 'iso-8859-1',
interpretNumericEntities: true
});
assert.deepEqual(detectedAsIso8859_1, { a: '☺' });
```
It also works when the charset has been detected in `charsetSentinel` mode.
### Parsing Arrays
**qs** can also parse arrays using a similar `[]` notation:
```javascript
var withArray = qs.parse('a[]=b&a[]=c');
assert.deepEqual(withArray, { a: ['b', 'c'] });
```
You may specify an index as well:
```javascript
var withIndexes = qs.parse('a[1]=c&a[0]=b');
assert.deepEqual(withIndexes, { a: ['b', 'c'] });
```
Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number to create an array.
When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving their order:
```javascript
var noSparse = qs.parse('a[1]=b&a[15]=c');
assert.deepEqual(noSparse, { a: ['b', 'c'] });
```
You may also use `allowSparse` option to parse sparse arrays:
```javascript
var sparseArray = qs.parse('a[1]=2&a[3]=5', { allowSparse: true });
assert.deepEqual(sparseArray, { a: [, '2', , '5'] });
```
Note that an empty string is also a value, and will be preserved:
```javascript
var withEmptyString = qs.parse('a[]=&a[]=b');
assert.deepEqual(withEmptyString, { a: ['', 'b'] });
var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c');
assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] });
```
**qs** will also limit arrays to a maximum of `20` elements.
Any array members with an index of `20` or greater will instead be converted to an object with the index as the key.
This is needed to handle cases when someone sent, for example, `a[999999999]` and it will take significant time to iterate over this huge array.
```javascript
var withMaxIndex = qs.parse('a[100]=b');
assert.deepEqual(withMaxIndex, { a: { '100': 'b' } });
```
This limit can be overridden by passing an `arrayLimit` option:
```javascript
var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 });
assert.deepEqual(withArrayLimit, { a: { '1': 'b' } });
```
If you want to throw an error whenever the array limit is exceeded, set the `throwOnLimitExceeded` option to `true`. This option will generate a descriptive error if the query string exceeds a configured limit.
```javascript
try {
qs.parse('a[1]=b', { arrayLimit: 0, throwOnLimitExceeded: true });
} catch (err) {
assert(err instanceof Error);
assert.strictEqual(err.message, 'Array limit exceeded. Only 0 elements allowed in an array.');
}
```
When `throwOnLimitExceeded` is set to `false` (default), **qs** will parse up to the specified `arrayLimit` and if the limit is exceeded, the array will instead be converted to an object with the index as the key
To prevent array syntax (`a[]`, `a[0]`) from being parsed as arrays, set `parseArrays` to `false`.
Note that duplicate keys (e.g. `a=b&a=c`) may still produce arrays when `duplicates` is `'combine'` (the default).
```javascript
var noParsingArrays = qs.parse('a[]=b', { parseArrays: false });
assert.deepEqual(noParsingArrays, { a: { '0': 'b' } });
```
If you mix notations, **qs** will merge the two items into an object:
```javascript
var mixedNotation = qs.parse('a[0]=b&a[b]=c');
assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } });
```
When a key appears as both a plain value and an object, **qs** will by default wrap the conflicting values in an array (`strictMerge` defaults to `true`):
```javascript
assert.deepEqual(qs.parse('a[b]=c&a=d'), { a: [{ b: 'c' }, 'd'] });
assert.deepEqual(qs.parse('a=d&a[b]=c'), { a: ['d', { b: 'c' }] });
```
To restore the legacy behavior (where the primitive is used as a key with value `true`), set `strictMerge` to `false`:
```javascript
assert.deepEqual(qs.parse('a[b]=c&a=d', { strictMerge: false }), { a: { b: 'c', d: true } });
```
You can also create arrays of objects:
```javascript
var arraysOfObjects = qs.parse('a[][b]=c');
assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] });
```
Some people use comma to join array, **qs** can parse it:
```javascript
var arraysOfObjects = qs.parse('a=b,c', { comma: true })
assert.deepEqual(arraysOfObjects, { a: ['b', 'c'] })
```
(_this cannot convert nested objects, such as `a={b:1},{c:d}`_)
### Parsing primitive/scalar values (numbers, booleans, null, etc)
By default, all values are parsed as strings.
This behavior will not change and is explained in [issue #91](https://github.com/ljharb/qs/issues/91).
```javascript
var primitiveValues = qs.parse('a=15&b=true&c=null');
assert.deepEqual(primitiveValues, { a: '15', b: 'true', c: 'null' });
```
If you wish to auto-convert values which look like numbers, booleans, and other values into their primitive counterparts, you can use the [query-types Express JS middleware](https://github.com/xpepermint/query-types) which will auto-convert all request query parameters.
### Stringifying
[](#preventEval)
```javascript
qs.stringify(object, [options]);
```
When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect:
```javascript
assert.equal(qs.stringify({ a: 'b' }), 'a=b');
assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c');
```
This encoding can be disabled by setting the `encode` option to `false`:
```javascript
var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false });
assert.equal(unencoded, 'a[b]=c');
```
Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`:
```javascript
var encodedValues = qs.stringify(
{ a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] },
{ encodeValuesOnly: true }
);
assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h');
```
This encoding can also be replaced by a custom encoding method set as `encoder` option:
```javascript
var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) {
// Passed in values `a`, `b`, `c`
return // Return encoded string
}})
```
_(Note: the `encoder` option does not apply if `encode` is `false`)_
Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values:
```javascript
var decoded = qs.parse('x=z', { decoder: function (str) {
// Passed in values `x`, `z`
return // Return decoded string
}})
```
You can encode keys and values using different logic by using the type argument provided to the encoder:
```javascript
var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str, defaultEncoder, charset, type) {
if (type === 'key') {
return // Encoded key
} else if (type === 'value') {
return // Encoded value
}
}})
```
The type argument is also provided to the decoder:
```javascript
var decoded = qs.parse('x=z', { decoder: function (str, defaultDecoder, charset, type) {
if (type === 'key') {
return // Decoded key
} else if (type === 'value') {
return // Decoded value
}
}})
```
Examples beyond this point will be shown as though the output is not URI encoded for clarity.
Please note that the return values in these cases *will* be URI encoded during real usage.
When arrays are stringified, they follow the `arrayFormat` option, which defaults to `indices`:
```javascript
qs.stringify({ a: ['b', 'c', 'd'] });
// 'a[0]=b&a[1]=c&a[2]=d'
```
You may override this by setting the `indices` option to `false`, or to be more explicit, the `arrayFormat` option to `repeat`:
```javascript
qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
// 'a=b&a=c&a=d'
```
You may use the `arrayFormat` option to specify the format of the output array:
```javascript
qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' })
// 'a[0]=b&a[1]=c'
qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' })
// 'a[]=b&a[]=c'
qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' })
// 'a=b&a=c'
qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'comma' })
// 'a=b,c'
```
Note: when using `arrayFormat` set to `'comma'`, you can also pass the `commaRoundTrip` option set to `true` or `false`, to append `[]` on single-item arrays, so that they can round trip through a parse.
When objects are stringified, by default they use bracket notation:
```javascript
qs.stringify({ a: { b: { c: 'd', e: 'f' } } });
// 'a[b][c]=d&a[b][e]=f'
```
You may override this to use dot notation by setting the `allowDots` option to `true`:
```javascript
qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true });
// 'a.b.c=d&a.b.e=f'
```
You may encode the dot notation in the keys of object with option `encodeDotInKeys` by setting it to `true`:
Note: it implies `allowDots`, so `stringify` will error if you set `decodeDotInKeys` to `true`, and `allowDots` to `false`.
Caveat: when `encodeValuesOnly` is `true` as well as `encodeDotInKeys`, only dots in keys and nothing else will be encoded.
```javascript
qs.stringify({ "name.obj": { "first": "John", "last": "Doe" } }, { allowDots: true, encodeDotInKeys: true })
// 'name%252Eobj.first=John&name%252Eobj.last=Doe'
```
You may allow empty array values by setting the `allowEmptyArrays` option to `true`:
```javascript
qs.stringify({ foo: [], bar: 'baz' }, { allowEmptyArrays: true });
// 'foo[]&bar=baz'
```
Empty strings and null values will omit the value, but the equals sign (=) remains in place:
```javascript
assert.equal(qs.stringify({ a: '' }), 'a=');
```
Key with no values (such as an empty object or array) will return nothing:
```javascript
assert.equal(qs.stringify({ a: [] }), '');
assert.equal(qs.stringify({ a: {} }), '');
assert.equal(qs.stringify({ a: [{}] }), '');
assert.equal(qs.stringify({ a: { b: []} }), '');
assert.equal(qs.stringify({ a: { b: {}} }), '');
```
Properties that are set to `undefined` will be omitted entirely:
```javascript
assert.equal(qs.stringify({ a: null, b: undefined }), 'a=');
```
The query string may optionally be prepended with a question mark:
```javascript
assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d');
```
Note that when the output is an empty string, the prefix will not be added:
```javascript
assert.equal(qs.stringify({}, { addQueryPrefix: true }), '');
```
The delimiter may be overridden with stringify as well:
```javascript
assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d');
```
If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option:
```javascript
var date = new Date(7);
assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A'));
assert.equal(
qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }),
'a=7'
);
```
You may use the `sort` option to affect the order of parameter keys:
```javascript
function alphabeticalSort(a, b) {
return a.localeCompare(b);
}
assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y');
```
Finally, you can use the `filter` option to restrict which keys will be included in the stringified output.
If you pass a function, it will be called for each key to obtain the replacement value.
Otherwise, if you pass an array, it will be used to select properties and array indices for stringification:
```javascript
function filterFunc(prefix, value) {
if (prefix == 'b') {
// Return an `undefined` value to omit a property.
return;
}
if (prefix == 'e[f]') {
return value.getTime();
}
if (prefix == 'e[g][0]') {
return value * 2;
}
return value;
}
qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc });
// 'a=b&c=d&e[f]=123&e[g][0]=4'
qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] });
// 'a=b&e=f'
qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] });
// 'a[0]=b&a[2]=d'
```
You could also use `filter` to inject custom serialization for user defined types.
Consider you're working with some api that expects query strings of the format for ranges:
```
https://domain.com/endpoint?range=30...70
```
For which you model as:
```javascript
class Range {
constructor(from, to) {
this.from = from;
this.to = to;
}
}
```
You could _inject_ a custom serializer to handle values of this type:
```javascript
qs.stringify(
{
range: new Range(30, 70),
},
{
filter: (prefix, value) => {
if (value instanceof Range) {
return `${value.from}...${value.to}`;
}
// serialize the usual way
return value;
},
}
);
// range=30...70
```
### Handling of `null` values
By default, `null` values are treated like empty strings:
```javascript
var withNull = qs.stringify({ a: null, b: '' });
assert.equal(withNull, 'a=&b=');
```
Parsing does not distinguish between parameters with and without equal signs.
Both are converted to empty strings.
```javascript
var equalsInsensitive = qs.parse('a&b=');
assert.deepEqual(equalsInsensitive, { a: '', b: '' });
```
To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null`
values have no `=` sign:
```javascript
var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true });
assert.equal(strictNull, 'a&b=');
```
To parse values without `=` back to `null` use the `strictNullHandling` flag:
```javascript
var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true });
assert.deepEqual(parsedStrictNull, { a: null, b: '' });
```
To completely skip rendering keys with `null` values, use the `skipNulls` flag:
```javascript
var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true });
assert.equal(nullsSkipped, 'a=b');
```
If you're communicating with legacy systems, you can switch to `iso-8859-1` using the `charset` option:
```javascript
var iso = qs.stringify({ æ: 'æ' }, { charset: 'iso-8859-1' });
assert.equal(iso, '%E6=%E6');
```
Characters that don't exist in `iso-8859-1` will be converted to numeric entities, similar to what browsers do:
```javascript
var numeric = qs.stringify({ a: '☺' }, { charset: 'iso-8859-1' });
assert.equal(numeric, 'a=%26%239786%3B');
```
You can use the `charsetSentinel` option to announce the character by including an `utf8=✓` parameter with the proper encoding if the checkmark, similar to what Ruby on Rails and others do when submitting forms.
```javascript
var sentinel = qs.stringify({ a: '☺' }, { charsetSentinel: true });
assert.equal(sentinel, 'utf8=%E2%9C%93&a=%E2%98%BA');
var isoSentinel = qs.stringify({ a: 'æ' }, { charsetSentinel: true, charset: 'iso-8859-1' });
assert.equal(isoSentinel, 'utf8=%26%2310003%3B&a=%E6');
```
### Dealing with special character sets
By default the encoding and decoding of characters is done in `utf-8`, and `iso-8859-1` support is also built in via the `charset` parameter.
If you wish to encode querystrings to a different character set (i.e.
[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the
[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library:
```javascript
var encoder = require('qs-iconv/encoder')('shift_jis');
var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder });
assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I');
```
This also works for decoding of query strings:
```javascript
var decoder = require('qs-iconv/decoder')('shift_jis');
var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder });
assert.deepEqual(obj, { a: 'こんにちは！' });
```
### RFC 3986 and RFC 1738 space encoding
RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible.
In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'.
```
assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c');
assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c');
assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c');
```

# Bytes utility
[![NPM Version][npm-image]][npm-url]
[![NPM Downloads][downloads-image]][downloads-url]
[![Build Status][ci-image]][ci-url]
[![Test Coverage][coveralls-image]][coveralls-url]
Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
## Installation
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```bash
$ npm install bytes
```
## Usage
```js
var bytes = require('bytes');
```
#### bytes(number｜string value, [options]): number｜string｜null
Default export function. Delegates to either `bytes.format` or `bytes.parse` based on the type of `value`.
**Arguments**
| Name | Type | Description |
|---------|----------|--------------------|
| value | `number`｜`string` | Number value to format or string value to parse |
| options | `Object` | Conversion options for `format` |
**Returns**
| Name | Type | Description |
|---------|------------------|-------------------------------------------------|
| results | `string`｜`number`｜`null` | Return null upon error. Numeric value in bytes, or string value otherwise. |
**Example**
```js
bytes(1024);
// output: '1KB'
bytes('1KB');
// output: 1024
```
#### bytes.format(number value, [options]): string｜null
Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
rounded.
**Arguments**
| Name | Type | Description |
|---------|----------|--------------------|
| value | `number` | Value in bytes |
| options | `Object` | Conversion options |
**Options**
| Property | Type | Description |
|-------------------|--------|-----------------------------------------------------------------------------------------|
| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. |
| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` |
| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `'.'`... Default value to `''`. |
| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. |
**Returns**
| Name | Type | Description |
|---------|------------------|-------------------------------------------------|
| results | `string`｜`null` | Return null upon error. String value otherwise. |
**Example**
```js
bytes.format(1024);
// output: '1KB'
bytes.format(1000);
// output: '1000B'
bytes.format(1000, {thousandsSeparator: ' '});
// output: '1 000B'
bytes.format(1024 * 1.7, {decimalPlaces: 0});
// output: '2KB'
bytes.format(1024, {unitSeparator: ' '});
// output: '1 KB'
```
#### bytes.parse(string｜number value): number｜null
Parse the string value into an integer in bytes. If no unit is given, or `value`
is a number, it is assumed the value is in bytes.
Supported units and abbreviations are as follows and are case-insensitive:
* `b` for bytes
* `kb` for kilobytes
* `mb` for megabytes
* `gb` for gigabytes
* `tb` for terabytes
* `pb` for petabytes
The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
**Arguments**
| Name | Type | Description |
|---------------|--------|--------------------|
| value | `string`｜`number` | String to parse, or number in bytes. |
**Returns**
| Name | Type | Description |
|---------|-------------|-------------------------|
| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. |
**Example**
```js
bytes.parse('1KB');
// output: 1024
bytes.parse('1024');
// output: 1024
bytes.parse(1024);
// output: 1024

Helper functions around Function call/apply/bind, for use in `call-bind`.
The only packages that should likely ever use this package directly are `call-bind` and `get-intrinsic`.
Please use `call-bind` unless you have a very good reason not to.
## Getting started
```sh
npm install --save call-bind-apply-helpers
```
## Usage/Examples
```js
const assert = require('assert');
const callBindBasic = require('call-bind-apply-helpers');
function f(a, b) {
assert.equal(this, 1);
assert.equal(a, 2);
assert.equal(b, 3);
assert.equal(arguments.length, 2);
}
const fBound = callBindBasic([f, 1]);
delete Function.prototype.call;
delete Function.prototype.bind;
fBound(2, 3);
```
## Tests
Clone the repo, `npm install`, and run `npm test`

npm install --save call-bound
```
## Usage/Examples
```js
const assert = require('assert');
const callBound = require('call-bound');
const slice = callBound('Array.prototype.slice');
delete Function.prototype.call;
delete Function.prototype.bind;
delete Array.prototype.slice;
assert.deepEqual(slice([1, 2, 3, 4], 1, -1), [2, 3]);
```
## Tests
Clone the repo, `npm install`, and run `npm test`

Create and parse HTTP `Content-Disposition` header
## Installation
```sh
$ npm install content-disposition
```
## API
```js
var contentDisposition = require('content-disposition')
```
### contentDisposition(filename, options)
Create an attachment `Content-Disposition` header value using the given file name,
if supplied. The `filename` is optional and if no file name is desired, but you
want to specify `options`, set `filename` to `undefined`.
```js
res.setHeader('Content-Disposition', contentDisposition('∫ maths.pdf'))
```
**note** HTTP headers are of the ISO-8859-1 character set. If you are writing this
header through a means different from `setHeader` in Node.js, you'll want to specify
the `'binary'` encoding in Node.js.
#### Options
`contentDisposition` accepts these properties in the options object.
##### fallback
If the `filename` option is outside ISO-8859-1, then the file name is actually
stored in a supplemental field for clients that support Unicode file names and
a ISO-8859-1 version of the file name is automatically generated.
This specifies the ISO-8859-1 file name to override the automatic generation or
disables the generation all together, defaults to `true`.
- A string will specify the ISO-8859-1 file name to use in place of automatic
generation.
- `false` will disable including a ISO-8859-1 file name and only include the
Unicode version (unless the file name is already ISO-8859-1).
- `true` will enable automatic generation if the file name is outside ISO-8859-1.
If the `filename` option is ISO-8859-1 and this option is specified and has a
different value, then the `filename` option is encoded in the extended field
and this set as the fallback field, even though they are both ISO-8859-1.
##### type
Specifies the disposition type, defaults to `"attachment"`. This can also be
`"inline"`, or any other value (all values except inline are treated like
`attachment`, but can convey additional information if both parties agree to
it). The type is normalized to lower-case.
### contentDisposition.parse(string)
```js
var disposition = contentDisposition.parse('attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt')
```
Parse a `Content-Disposition` header string. This automatically handles extended
("Unicode") parameters by decoding them and providing them under the standard
parameter name. This will return an object with the following properties (examples
are shown for the string `'attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt'`):
- `type`: The disposition type (always lower case). Example: `'attachment'`
- `parameters`: An object of the parameters in the disposition (name of parameter
always lower case and extended versions replace non-extended versions). Example:
`{filename: "€ rates.txt"}`
## Examples
### Send a file for download
```js
var contentDisposition = require('content-disposition')
var destroy = require('destroy')
var fs = require('fs')
var http = require('http')
var onFinished = require('on-finished')
var filePath = '/path/to/public/plans.pdf'
http.createServer(function onRequest (req, res) {
// set headers
res.setHeader('Content-Type', 'application/pdf')
res.setHeader('Content-Disposition', contentDisposition(filePath))
// send file
var stream = fs.createReadStream(filePath)
stream.pipe(res)
onFinished(res, function () {
destroy(stream)
})
})
```
## Testing
```sh
$ npm test
```

# content-type
[![NPM Version][npm-version-image]][npm-url]
[![NPM Downloads][npm-downloads-image]][npm-url]
[![Node.js Version][node-image]][node-url]
[![Build Status][ci-image]][ci-url]
[![Coverage Status][coveralls-image]][coveralls-url]
Create and parse HTTP Content-Type header according to RFC 7231
## Installation
```sh
$ npm install content-type
```
## API
```js
var contentType = require('content-type')
```
### contentType.parse(string)
```js
var obj = contentType.parse('image/svg+xml; charset=utf-8')
```
Parse a `Content-Type` header. This will return an object with the following
properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
- `type`: The media type (the type and subtype, always lower case).
Example: `'image/svg+xml'`
- `parameters`: An object of the parameters in the media type (name of parameter
always lower case). Example: `{charset: 'utf-8'}`
Throws a `TypeError` if the string is missing or invalid.
### contentType.parse(req)
```js
var obj = contentType.parse(req)
```
Parse the `Content-Type` header from the given `req`. Short-cut for
`contentType.parse(req.headers['content-type'])`.
Throws a `TypeError` if the `Content-Type` header is missing or invalid.
### contentType.parse(res)
```js
var obj = contentType.parse(res)
```
Parse the `Content-Type` header set on the given `res`. Short-cut for
`contentType.parse(res.getHeader('content-type'))`.
Throws a `TypeError` if the `Content-Type` header is missing or invalid.
### contentType.format(obj)
```js
var str = contentType.format({
type: 'image/svg+xml',
parameters: { charset: 'utf-8' }
})
```
Format an object into a `Content-Type` header. This will return a string of the
content type for the given object with the following properties (examples are
shown that produce the string `'image/svg+xml; charset=utf-8'`):
- `type`: The media type (will be lower-cased). Example: `'image/svg+xml'`
- `parameters`: An object of the parameters in the media type (name of the
parameter will be lower-cased). Example: `{charset: 'utf-8'}`
Throws a `TypeError` if the object contains an invalid type or parameter names.
