library0.4.0jsnpmunverified

Grunt plugin wrapping esperanto for transpiling ES6 modules to AMD, CommonJS, or UMD. Version 0.4.0 (last release) supports esperanto's `amdName` option. Designed for use with Grunt ~0.4.5. Key differentiator: integrates esperanto into Grunt build pipeline, providing file-based bundling with configurable output formats. No longer actively maintained; esperanto itself is deprecated in favor of rollup or other bundlers. Release cadence: sporadic, no releases since 2015.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

grunt.loadNpmTasks
✓ grunt.loadNpmTasks('grunt-esperanto');
✗ grunt.loadNpmTasks('esperanto');
Must use package name, not the underlying library.
esperanto task configuration
✓ grunt.initConfig({ esperanto: { ... } });
✗ grunt.initConfig({ esperanto: { options: { type: 'umd' } } });
Task name coincides with package name; no require() needed for the plugin itself.

Shows a minimal Gruntfile that loads the plugin, configures the task to transpile a module to UMD, and sets it as default.

// Install: npm install grunt-esperanto --save-dev // Gruntfile.js module.exports = function(grunt) { grunt.loadNpmTasks('grunt-esperanto'); grunt.initConfig({ esperanto: { options: { type: 'umd', separator: '\n' }, build: { files: { 'dist/bundle.js': ['src/module.js'] } } } }); grunt.registerTask('default', ['esperanto']); };
grunt --version
Debug
Known issues
deprecatedPackage is deprecated; esperanto is unmaintained. Use rollup or webpack instead.
fix
Migrate to rollup with @rollup/plugin-commonjs for similar functionality.
affects: >=0.0.0
gotchaThe task configuration key must be exactly 'esperanto'. Using any other name (e.g., 'esperanto2') will cause Grunt to ignore the configuration silently.
fix
Ensure the task name in initConfig matches the package name.
affects: >=0.0.0
gotchaThe 'type' option defaults to 'amd'; not setting it explicitly may produce unexpected output if you expect CJS or UMD.
fix
Always set options.type to the desired format.
affects: >=0.0.0
Errors
Common errors & fixes
Warning: Task "esperanto" not found. Use --force to continue.
grunt.loadNpmTasks('grunt-esperanto') missing or misspelled.
fix
Add grunt.loadNpmTasks('grunt-esperanto'); to your Gruntfile.
Fatal error: Cannot find module 'esperanto'
Esperanto library not installed. grunt-esperanto depends on it as a peer dependency.
fix
Run npm install esperanto --save-dev
Running "esperanto:build" (esperanto) task Warning: Unable to write "dest/bundle.js" file (Error code: ENOENT).
Destination directory does not exist.
fix
Ensure the dest folder exists or create it before running Grunt.
