Installation

You can install it from chrome store

Development

  1. You will need npm (install node.js for this) and gulp (npm install -g gulp) installed
  2. Clone this repo and run npm i to install dependencies
  3. Run gulp to build extension and watch for changes (to auto-rebuild) or gulp build to build without watching. Other available commands:
  • gulp eslint Checks js code (except 3rd-party files) with eslint
  • gulp package Builds extension and creates zip-archive which can be uploaded to chrome store
  1. In chrome navigate to chrome://extensions/, tick "Developer mode" checkbox and press "Load unpacked extension". Select dist folder.

All code that can be changed is in src directory. Files in src, such as background.js, content.js and popup.js, will be processed with webpack and babel, so ES6 syntax and imports can be used. Utils and config directories contain modules which can be imported. Static directory contains files that should be copied into dist without processing (like manifest, images or 3rd-party files). Look into gulpfile for details.
