# Image Library

A single-page, **backend-free** landing page that lists every image in `img/`,
lets you full-text search by filename, and copies an image's URL to your
clipboard when you click it. Built to be dropped onto an nginx server as plain
static files.

```
index.html                     the page
assets/styles.css              styling (auto light/dark)
assets/app.js                  search, rendering, clipboard logic
scripts/generate-manifest.mjs  scans img/ -> images.json
images.json                    generated manifest the page fetches
img/                           put your images here
```

## Why a manifest?

A browser cannot list a directory on its own, and "no backend" rules out an API
that would do it. So the file list is produced by a tiny build step:
`scripts/generate-manifest.mjs` walks `img/` and writes `images.json`. The page
fetches that file at runtime. Everything the server does is serve static files.

## Quick start

```sh
# 1. Add images (subfolders are fine)
cp ~/pictures/*.png img/

# 2. Build the manifest
node scripts/generate-manifest.mjs

# 3. Preview locally
python3 -m http.server 8080
#    -> open http://localhost:8080
```

Re-run step 2 whenever you add, rename, or delete images.

## Features

- **Search** — case-insensitive, multi-word with AND semantics. Every word must
  appear somewhere in the filename; prefix and word-boundary matches rank first.
  Matches are highlighted. Press `/` to focus the search box, `Esc` to clear.
- **Click to copy** — clicking a card copies the image's absolute URL
  (e.g. `https://your-host/img/logo.png`). A toast confirms it.
- **Lazy loading** — thumbnails load as you scroll, so large libraries stay fast.
- **No dependencies** — vanilla JS/CSS, no framework, no build tooling.

## Deploying on nginx

Copy the whole project (including the generated `images.json`) into a web root
and point a server block at it. See [`nginx.conf.example`](nginx.conf.example).

```sh
# build the manifest locally, then upload everything
node scripts/generate-manifest.mjs
rsync -av --delete ./ user@server:/var/www/image-library/
```

If you'd rather generate the manifest on the server, install Node there and run
the script after uploading images. Node is only needed for that step — nginx
never runs it.

### Clipboard over plain HTTP

`navigator.clipboard` only works in a **secure context** (HTTPS, or
`localhost`). The app detects this and falls back to a legacy copy method, which
works on plain HTTP in most browsers. For guaranteed behavior on a LAN host,
serve over HTTPS (e.g. a self-signed cert or a reverse proxy) — or just use
`http://localhost` while testing.

## Alternative: nginx autoindex

If you don't want a build step at all, you can enable nginx's directory listing
and have the page parse it, but that requires `autoindex on`, produces fragile
HTML scraping, and loses the manifest metadata. The manifest approach is
recommended.
