A Grunt plugin which acts as a wrapper for google-cloud.

Getting Started

This plugin requires Grunt ^1.0.1
If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:
npm install grunt-google-cloud --save-dev

Once the plugin has been installed, it may be enabled as so inside your Gruntfile:

Supported Services

The first version of this plugin current only supports Google Cloud Storage.

Google Cloud Storage

Uploads files to the specified bucket.


In your project's Gruntfile, add a section named gcs to the data object passed into grunt.initConfig().
  gcs: {
    options: {
      keyFilename: 'googlecloud.json',
      project: 'my-project-id',
      bucket: 'my-bucket-name',
      gzip: true,
      headers: {
        cacheControl: 'public, max-age=600'
      metadata: {
        'surrogate-key': 'gcs'
    dist: {
      cwd: 'dist',
      src: '**'

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
To aid in development, create a file named local-options.json with the following contents:
  "project": "",
  "bucket": "",
  "keyFilename": "",
  "testFiles": ""
This file will be read by Grunt and not be tracked by Git.
