Overview

Live Demo

This repo is extending the great work from Ben Smith published in his CppCon 2019 WebAssembly talk. The WebAssembly binaries are copied from Ben's fork of llvm-project.

Installation

# NPM
npm install clang.js

# Yarn
yarn add clang.js

Usage

import { init, run } from 'clang.js';

async function main() {
  await init({
    // The path to the wasm resources:
    // - clang.wasm
    // - lld.wasm
    // - memfs.wasm
    // - sysroot.tar
    path: 'https://cdn.jsdelivr.net/npm/clang.js/dist',
  });

  const code = `
    #include <iostream>
    using namespace std;

    int fib(int n) {
      if (n < 2) return n;
      return fib(n-1) + fib(n-2);
    }

    int main() {
      cout << "fib(10) = " << fib(10) << endl;
    }`;
  
  run(code);
}

main();

Roadmap

• [ ] Support for multiple code files
• [ ] Support operation WebGL
