Grunt plugin for running Google PageSpeed Insights.

grunt-pagespeed

Grunt plugin for running Google PageSpeed Insights

Run mobile and desktop performance tests for your deployed site using Google PageSpeed Insights, uses psi and gpagespeed.

This plugin is developed for Grunt 0.4.1 and is not tested for backward compatibility with Grunt 0.3.x.

Install this grunt plugin with the following command:

npm install grunt-pagespeed --save-dev

Add this to your project's Gruntfile.js gruntfile:

grunt.loadNpmTasks('grunt-pagespeed');

Or, add this to your project's Gruntfile.coffee gruntfile:

grunt.loadNpmTasks 'grunt-pagespeed'

Alternatively use load-grunt-tasks to load your plugins.

require('load-grunt-tasks')(grunt);

By default we recommend using the nokey option to test-drive PageSpeed Insights. This doesn't require any extra work on your part nor an API key.

For a production-level build process, registering for an API key is recommended from the Google Developer Console in order to use this module.

Run this task with the grunt pagespeed command.

This task is a multi task so any targets, files and options should be specified according to the multi task documentation.

###Usage Example

pagespeed: {
  options: {
    nokey: true,
    url: "https://developers.google.com"
  },
  prod: {
    options: {
      url: "https://developers.google.com/speed/docs/insights/v1/getting_started",
      locale: "en_GB",
      strategy: "desktop",
      threshold: 80
    }
  },
  paths: {
    options: {
      paths: ["/speed/docs/insights/v1/getting_started", "/speed/docs/about"],
      locale: "en_GB",
      strategy: "desktop",
      threshold: 80
    }
  }
}
