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.
