Screenshots

Usage

You can control the bot via the web page. Also, the following chat commands are available.

• ~join: The bot joins the voice channel you are currently in.
• ~leave
• ~stop: Stops playback.
• ~info: Prints information about the app (version, link to webpage, ...).
• ~record: Records the last 60 seconds of voice activity and saves them in the recordings folder.
• ~guildid: Prints the id of your discord server.

To issue a command, you must mention the bot in the message (e.g. ~join @my_bot_name).

Self-hosting

The app is deployed via Docker. The Docker container can be configured using environment variables. Sound files and recordings are stored in volumes. For details, see the next sections.

The http webserver is exposed under port 8000. When deploying, a reverse proxy may be used for https and optionally Gzip/Brotli compression (e.g. traefik, nginx, ...).

Prerequisites

To deploy, you need to create an application in the Discord Developer Portal under which your bot will run:

1. Go to the portal and add an application. Here, you can also set the username and profile picture of your bot.
2. Save the Client ID and Client Secret from the "General Information" tab for later.
3. Go to OAuth2 and add a URL of the following form: https://soundboard.domain/api/auth/login where soundboard.domain is the hostname under which your server should run.
4. Go to Bot, create a Bot and save the Bot token. Also check the box "Server Members Intent" under "Privileged Gateway Intents". This is required to validate user permissions.

Deploying

To run the app, create a docker-compose file:

version: "3"
services:
  soundboard:
    image: ghcr.io/dominikks/discord-soundboard-bot
    ports:
      - 8000:8000
    environment:
      - DISCORD_TOKEN=<bottoken>
      - DISCORD_CLIENT_ID=<clientid>
      - DISCORD_CLIENT_SECRET=<clientsecret>
      - ROCKET_SECRET_KEY=<secretkey>
      - ROCKET_DATABASES={postgres_database={url="postgres://postgres:<dbpassword>@db/postgres"}}
      - BASE_URL=<url>
    volumes:
      - sounds:/app/data/sounds
      - recordings:/app/data/recordings

  db:
    image: postgres
    environment:
      - POSTGRES_PASSWORD=<dbpassword>
    volumes:
      - db:/var/lib/postgresql/data

volumes:
  sounds:
  recordings:
  db:

The values from the Discord Developer Portal need to be passed to the bot via environment variables. The secret key should be randomly generated, for example with openssl rand -base64 32. It is used to encrypt cookies stored on the client. You can set the database password yourself. For details on the other values, see the table below.

Run the app via docker compose up -d. Stop via docker compose down.

The website should now be up, so that you can add the bot to your Discord server.

Configuration

Environment Variable	Meaning	Example
DISCORD_TOKEN	Required. Can be obtained in the Discord developer portal. Should be kept private.	ABCDE...dg
DISCORD_CLIENT_ID	Required. Can be obtained in the Discord developer portal.	ABCDE...dg
DISCORD_CLIENT_SECRET	Required. Can be obtained in the Discord developer portal. Should be kept private.	ABCDE...dg
BASE_URL	Required. The URL under which the app is reachable. Must not end with a slash.	https://soundboard.domain
ROCKET_SECRET_KEY	Required. A random key with which private cookies are encrypted that are placed on the client. Can be generated with openssl rand -base64 32.	hdjskfhs...dfkij=
LEGAL_URL	A url which is added as a link in the website footer. Can be used to link to a page containing legal information (e.g. privacy policy).	https://my.website/legal
RECORDING_LENGTH	The length in seconds for a recording using the built-in discord recorder. Defaults to 60.	30
RUST_LOG	Configure logging for the application. Defaults to info. For more details, see here.	discord_soundboard_bot=debug

Docker Volumes

Volume	Explanation
/app/data/sounds	Sounds are saved here.
/app/data/recorder	Contains recordings made by the sound-recorder feature.

By default, the app runs with UID 1000, so make sure that if you mount folders, they are owned by a user with that UID (e.g. chown 1000 <folder>).

Development

You need to have the latest Rust toolchain, Node, Docker and Docker Compose installed. Furthermore, ffmpeg, libpq-dev, cmake, pkg-config and libssl-dev need to be installed.

Then, create a .env file in the main project folder:

cat > .env <<'EOF'
DISCORD_TOKEN=<token>
DISCORD_CLIENT_ID=<clientid>
DISCORD_CLIENT_SECRET=<clientsecret>
BASE_URL=http://localhost:4200
RUST_LOG=discord_soundboard_bot=TRACE
POSTGRES_PASSWORD=<postgrespassword>
ROCKET_DATABASES={postgres_database={url=postgres://postgres:<postgrespassword>@localhost/postgres}}
EOF

Set the env variables DISCORD_TOKEN, DISCORD_CLIENT_ID, DISCORD_CLIENT_SECRET and BASE_URL as described under Configuration. Finally, you can start the service locally as follows:

• Start the dev sandbox using docker compose up -d.
• Start the backend using cargo run in backend/.
• Start the frontend using npm start in frontend/. The proxy will pass api requests data to the backend (see proxy.config.js).
• Access the frontend server under http://localhost:4200.
