    NodeJS ES Module Loader

    Loads ES modules and WebAssembly with CJS interop in Node, roughly according to https://github.com/nodejs/node-eps/blob/master/002-es6-modules.md.

    WASM support is currently only provided for Node 8 nightly.

    Follows the NodeJS resolution algorithm, loading modules first as CJS and then falling back to ES on import or export syntax failures. This effectively provides the "export {}" assumption to load an ES module.

    This does mean a double-parse, over the mjs approach currently being taken by Node.

    Built with the ES Module Loader polyfill 1.0 branch at https://github.com/ModuleLoader/es-module-loader.

    Installation

    npm install -g node-es-module-loader
    

    Usage

    Execute an ES module file:

    node-esml module.js
    

    For example, where module.js contains:

    import fs from 'fs';
    import {fn} from './local-es-module.js';
    import {wasmFn} from './local-wasm-binary.wasm';

    Note that only the default import form for CommonJS modules is supported.

    Also supports dynamic loading via the dynamic import syntax:

    export function lazyLoad(path) {
      return import(path);
    }

    Source maps for errors are fully supported through the source-map-support project.

    Source maps also work in Node 6 with the node --inspect flag via:

    node --inspect node_modules/.bin/node-esml module.js
    

    Programmatic Usage

    var NodeESModuleLoader = require('node-es-module-loader');
     
    var loader = new NodeESModuleLoader(/* optional basePath */);
     
    loader.import('x').then(function(m) {
      // ...
    });

    Caveats

    Alternative Babel options can be set with a local .babelrc file.
