Compiling Native to the Web

Hand-written JavaScript is great, but has it's limits.

The Toolchain

Made by Mozilla, adopted by the web.

asm.js

Strict subset of JavaScript, easy to optimize that allows JS engines to Ahead-of-time-compile asm.js code into very performant native code

Emscripten

• Open source compiler toolchain
• Cross-compiles C/C++ into JavaScript/asm.js

The Promise

Emscripten + asm.js let you run your C/C++ code in web browsers, approaching native speed

Sounds great, how can I use it?

It is just another export setting for game developers!

Libraries

• Box2DWeb – Port of Box2D
• Ammo.js - Port of Bullet Physics
• Both used by PlayCanvas
• … many more
