RPG JS
RPG-JS is a TypeScript-based framework and HTML5 canvas game engine for building two-dimensional role-playing games and massively multiplayer online worlds that run directly in web browsers. It provides a modular development environment combining strict compile-time type safety across game logic and events with specialized tools for drawing interactive maps, animated sprites, and world entities.
The framework supports real-time multiplayer networking by running an authoritative game server with client-side prediction and synchronization to maintain shared online worlds. Its architecture includes a hierarchical entity-component scene graph that updates and renders every frame, alongside a hybrid user interface layer that combines canvas-rendered head-up displays with standard document object model components for menus.
Additional capabilities cover the programmatic management of non-player characters, enemies, and triggers as interactive world events, as well as internationalization utilities for translating gameplay text and interface labels through decoupled language dictionaries.
Features
- MMORPG Server Hosting - Synchronizes server and client state to build massively multiplayer online role-playing games with shared game worlds.
- Multiplayer Game Engines - Maintains server authority and client prediction to run role-playing games online.
- Role-Playing Games - Provides type-safe tools for creating two-dimensional role-playing games running directly in web browsers.
