RuneJS Game Server

RuneJS is a RuneScape game server written in TypeScript and JavaScript. The aim of this project is to create a game server that is both fun and easy to use, while also providing simple content development systems.

The game server currently runs a build of RuneScape from October 30th-31st, 2006 (game build #435). No other builds are supported at this time, but may become available in the future.

RuneJS is completely open-source and open to all pull requests and/or issues. Many plugins have been added by contributor pull requests and we're always happy to have more!

Setup

Prerequisites

• docker and docker-compose
  • If on Windows, docker-compose comes with docker

Running the Game Server

1. Copy the config/server-config.example.json and paste it into the same folder using the name server-config.json
2. Go into your new server-config.json file and modify your RSA modulus and exponent with the ones matching your game client
   • You may also modify the server's port and host address from this configuration file
3. Build the docker image with docker-compose build
4. Run the game server with docker-compose up

The game server will spin up and be accessible via port 43594.

Game Client

The RuneScape Java Client #435 must be used to log into a RuneJS game server.
