Compile c/c++ inside ember projects using emscripten

Ember-CLI Emscripten

ember-cli-emscripten allows you to add emscripten-flavored c or c++ code to your ember app, then require the exposed functions and classes.

Installation

ember install:addon ember-cli-emscripten

Usage

This addon uses emscripten's embind to expose c/c++ functions to javascript. From the emscripten example, saved as app/compiled/math.cpp in your ember-cli app:

#include <emscripten/bind.h>

using namespace emscripten;

float lerp(float a, float b, float t) {
    return (1 - t) * a + t * b;
}

EMSCRIPTEN_BINDINGS(my_module) {
    function("lerp", &lerp);
}

ember-cli-emscripten then exports lerp via ES6, so you could use it like so:

import math from 'ember-app/compiled/math';

math.lerp(1, 2.5, 5)

TODO

• Right now every cpp file that gets compiled to js includes the emscripten runtime. Ideally this should only be included once per project.
• Expose emscripten emcc optimization options.
