Node-Emulator

An experimental, work in progress, Ragnarok Online emulator written with Node.js

Note: This project is for learning purposes only. For now, there is no intent to build a fully featured Ragnarok emulator.

Technology stack

• Node.js
• Redis
• MongoDB

Features

Single server setup

Unlike eAthena based emulators, I decided to try a single TCP/IP server instead of 3 (char, login and map). The main idea is to improve performance, code maintainability and reduce network traffic by eliminating inter-server packet exchange.

Multi-thread support

Node-Emulator uses Node.js cluster module to provide multi-thread support, taking advantage of multi-core systems to improve performance and a better use of system resources.
