Connects Discord and Minecraft Servers by sending messages back and forth without any mods or plugins.

In Action

Installation and usage

Create a Discord bot here: https://discordapp.com/developers/applications/me

Then, add the bot to your Discord server using the following link, replace the Client ID with that of your bot.

https://discordapp.com/oauth2/authorize?client_id=<CLIENT ID>&scope=bot

In your Minecraft server.properties, make sure you have the following and restart the server:

enable-rcon=true
rcon.password=<your password>
rcon.port=<1-65535>

Clone repository onto a server, edit config.json (see below for more info) and change any options, and then, in the repository folder:

$ yarn
$ yarn start

If you are running this locally, check the IS_LOCAL_FILE flag and related options below. Otherwise, perform the following command: On your server hosting (in a screen/tmux session or background process, make sure to replace your YOUR_URL with whatever URL you're using (localhost:8000 if running on the same server and default config) and PATH_TO_MINECRAFT_SERVER_INSTALL with the path to the Minecraft server installation, such as /usr/home/minecraft_server/):

tail -F /PATH_TO_MINECRAFT_SERVER_INSTALL/logs/latest.log | grep --line-buffered ": <" | while read x ; do echo -ne $x | curl -X POST -d @- http://YOUR_URL/minecraft/hook ; done

You can also easily Deploy to Heroku and the like, just be sure to edit YOUR_URL in the command to match accordingly.
