## Core Functionality
This is a browser extension to bridge YouTube with [Tube Archivist](https://github.com/tubearchivist/tubearchivist), your self hosted YouTube media server.
- Add your Tube Archivist connection details in the addon popup.
- On YouTube video pages, inject a download button to download that video and a subscribe button to subscribe to that channel.
- On YouTube channel pages, inject a button to subscribe to the channel or download the complete channel. Regarding the channel subpages, this follows the same rules as adding to the queue over the form.
- Throughout most places, hover over the video to reveal a download button for that video.
- Sync your cookies for yt-dlp.

## Roadmap
Join us on [Discord](https://www.tubearchivist.com/discord) and help us improve and extend this project. This is a list of planned features, in no particular order:
- [ ] Get download and subscribe status from TA to show on the injected buttons

- [ ] Implement download/subscribe button for playlists
- [ ] Implement download button for videos on playlist
- [X] Error handling for connection errors
- [X] Dynamically inject buttons with mutation observer

## Making changes to the JavaScript
The JavaScript does not require any build step; you just edit the files directly. However, there is config for eslint and prettier (a linter and formatter respectively); their use is recommended but not required. To use them, install `node`, run `npm i` from the root directory of this repository to install dependencies, then run `npm run lint` and `npm run format` to run eslint and prettier respectively.
