rot.js is a JavaScript/TypeScript toolkit for building roguelike games, providing dungeon generation, field-of-view, pathfinding, lighting, and an ASCII terminal-style Display. It works in browsers and Node.js and is largely feature-complete.

Use cases

• build a browser-based roguelike game
• generate procedural dungeons and mazes
• compute field of view and lighting for tile maps
• implement A* or Dijkstra pathfinding for game entities
• render ASCII characters with colors in a terminal-style grid
• create random number generators with seeds for reproducible maps

When to choose

• you are writing a roguelike or grid-based ASCII game in JavaScript or TypeScript
• you need battle-tested procedural generation and FOV algorithms without a full game engine
• you want a lightweight library usable in both browser and Node.js

When to avoid

• you need a full game engine with sprites, physics, or audio
• you are building a non-grid, non-turn-based game
• you need a toolkit in another language (consider libtcod or its ports instead)
