RPG JS: Lightweight JavaScript Framework for Text-Based RPGs

RPG JS is a lightweight JavaScript framework for building text-based roleplaying games that run in the browser. It handles game state, entities, combat, and more so developers can focus on content.

What is RPG JS?

RPG JS is an open-source JavaScript framework designed to help developers create text-based roleplaying games that run in a web browser. It provides a structure and tools for managing common RPG elements like:

  • Game state
  • Player character and NPC entities
  • Turn-based combat system
  • Dialogue trees and text parsing
  • Inventory, quest, and equipment systems
  • Saving and loading game data

With RPG JS handling the underlying game logic, developers can focus on creating game content like story, text, combat encounters, etc. It uses a modular architecture so developers can use what they need and customize or extend anything. It also includes helpful tools like text variable replacement and dialogue parsers.

Games made with RPG JS target the browser allowing them to run on any device with a modern web browser. The framework aims to bring back classic text RPG experiences while taking advantage of the accessibility and reach of web games. It has an MIT open-source license.
