Muse is a **highly-opinionated midwestern self-hosted** Discord music bot **that doesn't suck**. It's made for small to medium-sized Discord servers/guilds (think about a group the size of you, your friends, and your friend's friends).

## Running

Muse is written in TypeScript. You can either run Muse with Docker (recommended) or directly with Node.js. Both methods require API keys passed in as environment variables:

- `DISCORD_TOKEN` can be acquired [here](https://discordapp.com/developers/applications) by creating a 'New Application', then going to 'Bot'.
- `SPOTIFY_CLIENT_ID` and `SPOTIFY_CLIENT_SECRET` can be acquired [here](https://developer.spotify.com/dashboard/applications) with 'Create a Client ID'.
- `YOUTUBE_API_KEY` can be acquired by [creating a new project](https://console.developers.google.com) in Google's Developer Console, enabling the YouTube API, and creating an API key under credentials.

Muse will log a URL when run. Open this URL in a browser to invite Muse to your server. Muse will DM the server owner after it's added with setup instructions.

### Versioning

The `master` branch acts as the developing / bleeding edge branch and is not guaranteed to be stable.

When running a production instance, I recommend that you use the [latest release](https://github.com/codetheweb/muse/releases/).


### 🐳 Docker

There are a variety of image tags available:
- `:2`: versions >= 2.0.0
- `:2.1`: versions >= 2.1.0 and < 2.2.0
- `:2.1.1`: an exact version specifier
- `:latest`: whatever the latest version is

(Replace empty config strings with correct values.)

```bash
docker run -it -v "$(pwd)/data":/data -e DISCORD_TOKEN='' -e SPOTIFY_CLIENT_ID='' -e SPOTIFY_CLIENT_SECRET='' -e YOUTUBE_API_KEY='' codetheweb/muse:latest
```

This starts Muse and creates a data directory in your current directory.

**Docker Compose**:

```yaml
version: '3.4'

services:
  muse:
    image: codetheweb/muse:latest
    restart: always
    volumes:
      - ./muse:/data
    environment:
      - DISCORD_TOKEN=
      - YOUTUBE_API_KEY=
      - SPOTIFY_CLIENT_ID=
      - SPOTIFY_CLIENT_SECRET=
```

### Node.js

**Prerequisites**: Node.js, ffmpeg

1. `git clone https://github.com/codetheweb/muse.git && cd muse`
2. Copy `.env.example` to `.env` and populate with values
3. I recommend checking out a tagged release with `git checkout v[latest release]`
4. `yarn install` (or `npm i`)
5. `yarn build` (or `npm run build`)
6. `yarn start` (or `npm run start`)

**Note**: if you're on Windows, you may need to manually set the ffmpeg path. See [#345](https://github.com/codetheweb/muse/issues/345) for details.

## ⚙️ Additional configuration (advanced)

### Cache

By default, Muse limits the total cache size to around 2 GB. If you want to change this, set the environment variable `CACHE_LIMIT`. For example, `CACHE_LIMIT=512MB` or `CACHE_LIMIT=10GB`.

### Bot-wide commands

If you have Muse running in a lot of guilds (10+) you may want to switch to registering commands bot-wide rather than for each guild. (The downside to this is that command updates can take up to an hour to propagate.) To do this, set the environment variable `REGISTER_COMMANDS_ON_BOT` to `true`.
