# rimgu: image host alternative frontend
## rimgu is an alternative frontend / proxy for imgur
It's read-only and works without browser JavaScript. Images and albums can be viewed without wasting resources and anyonymity from downloading and running tracking scripts. No sign-up nags.
It's lightweight and easy to configure.
Inspired by and (soon) integratable with:
* [searx](https://github.com/searx/searx)
* [teddit](https://codeberg.org/teddit/teddit) ([integration](https://codeberg.org/teddit/teddit/pulls/249))
* [Privacy Redirect](https://github.com/SimonBrazell/privacy-redirect) ([integration](https://github.com/SimonBrazell/privacy-redirect/pull/303))
* [nitter](https://github.com/zedeus/nitter)
* [bibliogram](https://sr.ht/~cadence/bibliogram/)
Features:
- [x] URL-compatible with i.imgur.com - just replace the domain in the URL
- [x] Images and videos (gifv, mp4) returned directly
- [x] Galleries with comments
- [x] Albums
- [x] Supports http(s) forward proxy
This is currently very early stage software. Some things left to implement (contributions welcome!):
- [ ] User page
- [ ] Tag page
- [ ] Streaming (currently media is downloaded in full in rimgu before it's returned)
- [ ] Localization/internationalization
- [ ] Pretty CSS styling (responsive?)
- [ ] Automatically fetch / rotate / renew client ID
- [ ] Support for other popular image sites than only imgur
- [ ] Prometheus metrics
Things that are *currently* considered out of scope:
* Uploading/commenting/voting/etc - rimgu is read-only for now.
* Caching, authentication, serving HTTPS, rate limiting etc - Just use a proxy or load balancer like squid/haproxy/envoy/nginx/traefik/caddy.
* Anything requiring client-side JS or client-side directly interacting with upstream servers
## Building
### Locally
Dependencies:
* node.js >= v16 (earlier most likely works fine)
```
$ npm install && npm run build
```
### Docker
```
$ docker build -t rimgu:latest .
```
## Running
### Locally
```
$ node dist/index.js
```
### Docker
```
$ docker run -p 8080:8080 -e -it RIMGU_ADDRESS=0.0.0.0 -e RIMGU_PORT=8080 rimgu:latest
```
If you decide to run a public instance, consider opening an issue to have it listed here :)
## Configuration
Rimgu is configured via environment variables. See available variable in [src/config.ts](./src/config.ts).
### API and client ID
Media and galleries can be scraped without authorization through the public web interface.
Some imgur functionality (comments, full albums) requires a provisioned client ID to authenticate requests.
You can get a client ID by opening https://imgur.com in a web browser and looking for requests to `https://api.imgur.com/...?client_id=1234567deadbeef` under "Network" in the developer console.
__To run without API/key__: `RIMGU_USE_API=false`
__To run with API/key__: `RIMGU_USE_API=true RIMGU_IMGUR_CLIENT_ID=1234567deadbeef`
This key may be used to track you and could be banned when overused. Keep this in mind before exposing a public instance with a client key associated with your personal imgur account. Consider any ToS you may have signed before associating a personal imgur account with a public instance.
