Introduction

A service that connects multiple Hypixel guilds and Discord servers together. This project is made to be fully flexible and customisable, offering a high quality user experience while keeping it simple.

DISCLAIMER: This project interacts with Hypixel in an unintended way by simulating a minecraft client and by processing packets which might get you banned if over-abused too much.
Just like any other modification and service that interacts with Hypixel servers, this goes without saying: "Use at your own risk"

Migrating To 3.x.x

Breaking changes:

  • config.yaml has been reformatted. Check the new config_example.yaml and compare it with the old config file.
  • Version 3.x websocket is incompatible with older versions. You cannot connect the new version with the old one.
  • Chat Commands have been moved to their own instance in config.yaml. Only enable one instance when using websocket.
  • Project has been moved to ESM. Old plugins that still use commonjs will not work anymore.
  • The Minecraft bot and websocket have been stripped down to bare metal. Any plugins that use those features must be updated accordingly.
  • The punishment system has been revised and now uses ./configs/ to save its state as a file. The ./configs/ directory is now git-ignored.
  • Any unexpected errors during the launching phase will result in a shutdown with an exit code instead of sending a notification.

Available Plugins

Application has an official public API and supports custom plugins to enhance potential.
Loaded plugins can be configured in the config.yaml file when configuring the app.
To create custom plugins see Documentation And Tutorials.

These are the supported official plugins that come bundled with the application:

Plugin Description Importance Notice
auto-restart Schedule restarting every 24 hours Essential A process monitor is required to restart the application after it shuts down. Not periodically restarting can lead to high RAM usage.
limbo-plugin Forces Minecraft client to stay in Hypixel limbo Essential Being outside of limbo for prolonged periods can lead to the account being banned. Only disable if required.
punishment-plugin Enforces punishments and prevents punishment evasion Recommended Plugin will mute users but won't ban them, instead it will send a notification in officer chat.
warp-plugin Warp players out of their lobbies Quality of Life Incompatible with limbo-plugin. Disable one before enabling the other one.
reaction-plugin Send a greeting/reaction message when a member joins/leaves or is kicked from the guild Quality of Life N/A
dark-auction Send a reminder when a skyblock dark auction is starting Quality of Life Sends a reminder 5 minutes and 1 minute before the dark auction.

How to use override

From In-game: /gc !override /guild party
From Discord: /override /guild party


Metrics

hypixel-guild-discord-bridge supports Prometheus metrics, and it is enabled by default on port 9095. Many metrics are automatically collected in memory and await prometheus to scrap them.

Available Metrics

These are the currently monitored metrics. No usernames or anything personal is monitored. All metrics have the default prefix guild_bridge_. It can be changed in config.yaml under metrics.

Metric Description Source metadata
PREFIX_guild_exp_total Guild total experience Hypixel API /guild end point name: Guild name
PREFIX_guild_exp_game Guild experience per game Hypixel API /guild end point name: Guild name, type: game type
PREFIX_guild_members Guild members count Hypixel API /guild end point name: Guild name
PREFIX_chat Messages count of all chat In-game guild chat/Discord bot location: Discord, webhook, in-game.
scope: private, officer, public chat.
instance: name of the source registered in config.yaml
PREFIX_command Commands usage count Discord commands interactions and in-game chat commands Same as chat metrics + command: command name
PREFIX_event Events count Discord server events and in-game chat same as chat metrics + event: event name (e.g. offline, join, mute, etc.)
PREFIX_guild_members_online Guild current online members In-game periodic execution of /guild list name: Guild name

Metrics Config

In-game periodic command execution for metrics are disabled by default. Automatically sending commands non-stop to Hypixel might get the client banned for blatant automation. Although the chance is next to none, it is disabled for safe measures.

Metrics With Grafana

Metrics can be directly used from the Prometheus server by querying it directly. However, to visualise the data, another server is required to do the job. Grafana is one of the most popular and easy to use out there. Many tutorials exist on the internet showcasing Grafana setups and configs.

Here are examples of Prometheus queries and their results displayed using Grafana:

  • Guild Chat:
sum(increase(guild_bridge_chat[1h])) by (scope,location)

  • Guild Total Experience:
increase(guild_bridge_guild_exp_total[10m])

  • Guild Current Online Members:
guild_bridge_guild_members_online

Installing and Running

Prerequisites

Download

Clone and download the complete project by using Git tool:

git clone https://github.com/aidn3/hypixel-guild-discord-bridge

Alternatively, download the source code directly without any revisions. (Updating the service will be difficult)

Configure

  • Explore the project files and copy the contents of .config_example.yaml into config.yaml
  • Open config.yaml and fill in the information (Security: config.yaml contains sensitive information. Keep it safe!)
  • In config.yaml fill out general.hypixelApiKey and discord and minecraft.instances
  • (Optional) for Advanced users only: Edit other options in config.yaml to fine tune the bridge

Install

Install dependencies and libraries by executing the command:

npm install

New dictionary node_modules will be generated containing all required files.

Run

Start the service by executing command:

npm start

Advanced

This section is for advanced users who wish to run a bridge that supports thousands of online players with dozens of connected guilds.

Sockets And Cluster Nodes

Bridge supports cluster mode. That means, the bridge can be divided into smaller parts and be hosted on different servers and all be connected via sockets.
When to use cluster mode:

  • If more than 2 Minecraft accounts are connected from same host server. Hypixel will IP ban all accounts for " compromised account" or "suspicious activity"
  • If a Minecraft account owner wishes to hold the login details by hosting a part of the bridge on their server

Node Modes

Each node supports two modes: client and server. Only one server can exist and all clients will connect to it (Server must also not be behind a firewall).

  • Server mode is just an extension of client mode. It supports instances as well as Discord bridge and minecraft bots
  • Server's goal is to only forward all events and data and distribute it to all clients
  • Server will not wait for client to reconnect when forwarding events. Clients however will wait to re-sync with server

Setup Cluster

All configurations will be in config.yaml under socket section.

  • Follow the Setup process for each node, but don't start them yet
  • Set config enabled to true.
  • Choose a secure password and set it under key. (Security: Anyone can hijack the bridge if it is easily guessable)
  • Choose which node shall act as the "Server" and set it under config type
  • Set the config uri to the server node socket to connect to
  • Start all nodes
