Need Help?

If you wonder how to install or use this plugin, or even Grunt itself, you should check out our "Discover Grunt" book.

It starts at the very beginning (including how to properly set-up your command-line on Windows and Mac OS X), and goes beyond the official Getting Started guide.

Getting Started

This plugin requires Grunt ~0.4.1

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-http-upload --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:


The "http_upload" task


In your project's Gruntfile, add a section named http_upload to the data object passed into grunt.initConfig().


  http_upload: {
    your_target: {
      options: {
        url: '<%= config.apiKey %>',
        method: 'PUT',
        data: {
          someKey: 'some value'
      src: '<%= yeoman.dist %>/',
      dest: 'myField'




Type: String Default value: ''

This is the full URL to which you can upload a file. You can append some variables, like an API token.


Type: String Default value: 'POST'

The HTTP method to use to upload the file. Look in the API documentation you want to use, this is usually POST or PUT.

Type: Object DefaultValue: {}

Any form data fields to be sent in addition to the file upload


Type: String Default value: ''

The local path of the file you wish to upload, using the current working directory as a reference. You can upload only 1 file at a time.


Type: String Default value: ''

The field name of the file to be uploaded, on the API side.

Usage Examples

Default Options

In this example, the default POST method is used to upload the local picture ./images/status.jpg to Basecamp. Their API can be accessed through the URL (using Basic Auth). When creating an attachment in Basecamp, the "dest" field name is not important, so you can set it to anything (img in this case). method is set to "POST", but could have been omitted as this is the default value.

  http_upload: {
    basecamp: {
      options: {
        url: '',
        method: 'POST'
      src: 'images/status.jpg',
      dest: 'img'


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.

You should fork this repo, and issue a Pull Request with your proposed changes.

Roadmap ideas

For now the upload is limited to 1 file per target. This could change if I find a scenario needing it. Also, it is not possible to add additional payload (no custom data). A lot of API require the Authentication to be sent through the Headers, so this might be one of the next improvement.
