discord-jabber-transport-bot

Simple transport bot between Discord channel and Jabber (XMPP MUC) conference. You can join several conferences on one bot instance.

How to start

• You need a working installation of Node.js on the machine this bot will run on. npm is installed with Node.js.
• Get latest stable release.
• Install dependencies: npm ci.
• Create configuration file:

  cp config/development.cjson.sample config/development.cjson
  

  Create production.cjson for production mode (NODE_ENV=production).
• Edit configuration files. See section Adding Bot to Discord Guild below.
• Start application: nodejs ./app.js or npm start.
• Type !ping in Discord channel to check "pong" answer.

Adding Bot to Discord Guild

1. You need to create an application on My Apps page.

2. Create an invitation URL as described on Bot Authorization Flow documentation page. For ease of use, it is recommended to use this website: https://discordapi.com/permissions.html.

   Bot requires 3 permissions: READ_MESSAGES, SEND_MESSAGES, EMBED_LINKS.

   There are two optional permissions: MANAGE_CHANNELS and MANAGE_WEBHOOKS (both requires Two-Factor Authentication).

   Set MANAGE_CHANNELS if you want to bot set channel topic from jabber to Discord (one way sync).

   Set MANAGE_WEBHOOKS permission if you want to bot send messages to Discord on behalf of jabber user nickname.

3. You need to navigate to this URL, you'll be prompted to add the bot to a guild in which you have proper permissions. On acceptance, the bot will be added.

Debugging

Set environment variable DEBUG to values according to debug package documentation. This application uses values: info, error, error:app, error:jabber, error:discord, debug:app, debug:jabber, debug:discord.

For example, run in Linux terminal:

• $> export DEBUG=*,-xmpp:client
• $> node app.js

If DEBUG is not set then it sets to log all except debug settings: app.js#L3-L5.

Docker

Also you can run it in a docker container:

1. cd ~/projects/discord-xmpp-transport-bot
2. sudo docker run --rm -it -v $(pwd):/src:rw mkenney/npm:node-7.7-alpine "npm ci"
3. sudo docker run --rm -it -v $(pwd):/src:ro mkenney/npm:node-7.7-alpine "npm run start-debug"

Or use Dockerfile:

1. Build the image: sudo docker build -t discord-xmpp-transport-image .
2. Run the container: sudo docker run -it --rm --name dscrd-xmpp-brdg -e NODE_ENV=production -e DEBUG=info,error:*,debug:* discord-xmpp-transport-image

Run using docker-compose:

• Development mode: sudo docker-compose -f docker-compose.yml -f docker-compose.dev.yml up --build
