v83 MapleStory Server emulator written in TypeScript. Inspired by projects like HeavenMS.

This project has been sidetracked for @perion/perion.

• Easy development environment
• Uses a microservice architecture where state is decoupled into center, login, shop, and channel servers
• Currently runs as a cluster of processes, with future support for running each service independently
• Advanced metrics using Prometheus
• Will support both the NX and WZ format
• Will use multithreading to delegate compute-heavy tasks
• Will use token-based authentication for intraserver communication

• Fork the repository
• Run npm install in the project directory to install the dependencies

• Class names will use PascalCase
• Filenames, functions, and variable names will use camelCase
• SQL tables and columns will use snake_case
• Tests will be written as *.test.ts and placed in the test/ directory

• Run the server with npm run start
• Run the unit tests with npm run test

• Download the client files here
