allegro-tsAllegro 4 for the Browser

A TypeScript game library that faithfully maps the classic Allegro 4 C API to HTML5 Canvas.

Familiar API

If you've used Allegro 4 in C/C++, you already know allegro-ts. Functions like set_gfx_mode(), draw_sprite(), and install_keyboard() work just as you'd expect.

HTML5 Canvas Rendering

All drawing goes through the browser's 2D Canvas API. Bitmaps, primitives, sprites, fonts, and pixel manipulation are fully supported.

Full Input Support

Keyboard, mouse, and touch input are handled with the same event-driven model as the original Allegro 4 library.

Audio Playback

Load and play WAV/MP3 samples via the Web Audio API. MIDI playback is supported through a built-in General MIDI player.

TypeScript First

Written in TypeScript with full type definitions exported. Import only what you need or use the global mode for a script-tag style workflow.

Zero Dependencies

No runtime dependencies. Just allegro-ts and the browser. Works with any bundler (Vite, webpack, esbuild) or directly as an ES module.
