ESLint Plugin and Config for the Google JavaScript Style Guide

Closure Linter - ESLint Plugin and Config for the Google JavaScript Style Guide

A heavily customized ESLint config and plugin for JavaScript following the Google JavaScript style guide.

Check out the demo page.

Google Style Guide Specific Features

• Recognizes goog.scope as an immediately invoked function expression (IIFE) that doesn't increase the indent.

  goog.scope(function() {
  var noIndent = 2;
  });

• Recognizes goog.provide and goog.require.

  goog.provide('my.module');
  goog.require('other.module');
  
  my.module.Foo = other.module.Bar;

• Avoids flagging typedef, export and other type-related tags as unused.

  /** @export {number} */
  my.module.foo = 2;

See the Google JavaScript style guide for the rest of the rules.

Developing

Pull requests are always welcome. To get started, install Bazel, Google's open-source build system, and Yarn, an NPM replacement.

A typical development flow looks like this:

1. make develop to download dependencies from NPM and to link the projects together.
2. make test to ensure everything works first.
3. Add a feature or fix a bug.
4. make test
5. git commit
6. git push
