Available generators:


Sets up a new Chrome Extension, generating all the boilerplate you need to get started.

yo chrome-extension

gulp tasks


The generator supports ES 2015 syntax through babel transforming. You may have a source files in script.babel if your project has been generated without --no-babel options. While developing, When those of source has been changed, gulp babel should be run before test and run a extension on Chrome.

gulp babel

If you would like to have a continuous transforming by babel you can use watch task


Watch task helps you reduce your efforts during development extensions. If the task detects your changes of source files, re-compile your sources automatically or Livereload(chromereload.js) reloads your extension. If you would like to know more about Live-reload and preview of Yeoman? Please see Getting started with Yeoman and generator-webapp for your understanding.

gulp watch

Build and Package

It will build your app as a result you can have a distribution version of the app in dist. Run this command to build your Chrome Extension app.

gulp package


  • --no-babel

    If you wouldn't use Babel ES2015 transpiler.

  • --test-framework=[framework]

    Defaults to mocha. Can be switched for another supported testing framework like jasmine.

  • --all-permissions

    All of permissions of chrome extension will be shown.

ES2015 and babel

ES2015 is the default option in the generator that means you can use es2015 now for developing the Chrome extensions. However, at this moment, you need to execute babel task of gulp to compile to test and run your extension on Chrome, because ES2015 is not full functionality on Chrome as yet.

The sources written by es2015 is located at scripts.babel and runnable sources are will be at script after compiling by gulp babel. May you don't want to use babel and ES2015 use --no-babel option when scaffolding a new project.

yo chrome-extension --no-babel


This generator supports sass through --sass options and generate scss boilerplate files at styles.scss that those of scss files will be compiled to styles via gulp style task. To do this, libsass is featured in the generator. Please see this for further information.

yo chrome-extension --sass
