grunt-es6-module-transpiler

0.0.1 verified Fri May 01 auth: no javascript deprecated

A Grunt task for transpiling ES6 module import/export syntax into AMD, CommonJS, YUI, or globals. Current version 0.5.0 (released Oct 2013) supports es6-module-transpiler v0.3.0. Legacy plugin for Grunt 0.4.x with no updates since 2013. Key differentiator: allowed early ES6 module transpilation in Grunt builds but is now outdated; replaced by modern tools like Babel. Requires peer dependency grunt ~0.4.1. Not maintained.

Common errors

error Warning: Task "transpile" not found ↓

cause Missing grunt.loadNpmTasks('grunt-es6-module-transpiler') in Gruntfile.

fix

Add grunt.loadNpmTasks('grunt-es6-module-transpiler'); after initConfig.

error TypeError: Cannot read property 'files' of undefined ↓

cause Missing files configuration in the transpile target.

fix

Ensure each target has a files array with src and dest (or expand pattern).

Warnings

deprecated Package unmaintained since 2013. Use modern tooling like Babel or esbuild. ↓

fix Migrate to a current transpiler (e.g., @babel/preset-env with Grunt or standalone).

breaking v0.5.0 removed transpile:enable task due to es6-module-transpiler v0.3.0 changes. ↓

fix Remove usage of transpile:enable; the feature no longer exists.

gotcha Strict mode is enforced; Chai's arguments.callee usage will cause errors. ↓

fix Use expect.js or other assertion libraries that don't rely on non-strict features.

Imports

Gruntfile config
wrong
```
const transpile = require('grunt-es6-module-transpiler')
```
correct
```
grunt.initConfig({ transpile: { ... } })
```
Plugin is loaded via grunt.loadNpmTasks, not imported directly. Configuration is set in Gruntfile.

Quickstart

Gruntfile configuration that transpiles ES6 modules from lib/ to AMD format in tmp/.

module.exports = function(grunt) {
  grunt.initConfig({
    transpile: {
      main: {
        type: 'amd',
        files: [{
          expand: true,
          cwd: 'lib/',
          src: ['**/*.js'],
          dest: 'tmp/'
        }]
      }
    }
  });
  grunt.loadNpmTasks('grunt-es6-module-transpiler');
  grunt.registerTask('default', ['transpile']);
};
