Matrix Discord Bridge

A bridge between Matrix and Discord. Currently the bridge is in Beta and quite usable for everyday bridging, with one or two bugs cropping up.

Build Status

PRs

PRs are graciously accepted, so please come talk to us in #discord-bridge:matrix.org about any neat ideas you might have. If you are going to make a change, please merge it with the develop branch :).

Issues

You can also file bug reports/ feature requests on Github Issues which also helps a ton. Please remember to include logs. Please also be aware that this is an unoffical project worked on in my (Half-Shot) spare time.

Setting up

(These instructions were tested against Node.js v6.9.5 and the Synapse homeserver)

Setup the bridge

  • Run npm install to grab the dependencies.

  • Run npm run-script build to build the typescript.

  • Copy config/config.sample.yaml to config.yaml and edit it to reflect your setup.

    • Note that you are expected to set domain and homeserverURL to your public host name. While localhost would work, it does not resolve correctly with Webhooks/Avatars.
    bridge:
    domain: "example.com"
    homeserverUrl: "https://example.com:8448"
    
  • Run node build/src/discordas.js -r -u "http://localhost:9005" -c config.yaml

  • Modify your HSs appservices config so that it includes the generated file.

    • e.g. On synapse, adding to app_service_config_files array in homeserver.yaml
    app_service_config_files:
    - "discord-registration.yaml"
    
    • Copy discord-registration.yaml to your Synapse's directory.

3PID Protocol Support

This bridge support searching for rooms within networks via the 3pid system used in clients like Riot. However, it requires a small manual change to your registration file. Change the end of discord-registration.yaml to `protocols: ["discord"]`` and restart both your bridge and synapse. Any new servers/guilds you bridge should show up in the network list on Riot and other clients.

Setting up Discord

  • Create a new application via https://discordapp.com/developers/applications/me/create
  • Make sure to create a bot user. Fill in config.yaml
  • Run npm run-script getbotlink to get a authorisation link.
  • Give this link to owners of the guilds you plan to bridge.
  • Finally, you can join a room with #_discord_guildid_channelid
    • These can be taken from the url ("/$GUILDID/$CHANNELID") when you are in a channel.
    • Riot (and other clients with third party protocol support) users can directly join channels from the room directory.
  • You can use Webhooks to make messages relayed by the bridge not nested by the bot user. This will also display the avatar of the user speaking on matrix with their messages.
    • The bot should create this automatically, but if not perform the following:
      • Enable Manage Webhooks on the role added by the bot.
      • Add the _matrix Webhook for each channel you'd like to enable this feature on.

Running the Bridge

  • For the bot to appear online on Discord you need to run the bridge itself.
  • npm start
