Syncs a local project with the Mozu Developer Center.

Getting Started

This plugin requires Grunt.

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-mozu-appdev-sync --save-dev

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


The "mozusync" task


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

  mozusync: {
    options: {
      // Task-specific options go here.
      applicationKey: 'namespace.applicationname.1.0.0.Release',
      context: {
        developerAccount: {
          emailAddress: ''
        developerAccountId: 2
      noclobber: true
    upload: {
      // Target-specific file lists and/or options go here.
      src: ['./assets/dist/**/*']
    del: {
      // If you're using the grunt-contrib-watch adapter,
      // a separate task for deletion is usually necessary.
      // The delete task does not use the `files` array.
      options: {
        action: 'delete'
      src: ['./assets/dist/**/*'],
      remove: []

A Common Way To Do It

The above depicted configuration is nice and simple, but it does hardcode specific Mozu environment information into the Gruntfile. You may be moving your project work from theme to theme in your Mozu account, or sharing your work with other developers. It's best to keep your Mozu environment information separate from the Gruntfile itself.

If you used the Mozu Yeoman theme generator to scaffold your theme project folder, or you are familiar with the Mozu Node SDK, you know that it likes to store credentials in a file called mozu.config.json. You can maintain this file, and then hook it up to the Grunt task, using the following pattern, which takes advantage of Grunt's template interpolation:


  mozuconfig: require('./mozu.config.json'),

  mozusync: {
    options: {
      applicationKey: '<%= mozuconfig.workingApplicationKey %>',
      context: '<%= mozuconfig %>',
      noclobber: true
    // individual mozusync task config below


The Yeoman theme generator will put this in a Gruntfile for you, either by creating a new one or modifying your existing one.

You can also install the Mozu App generator and use it to create a mozu.config.json file.

To install the generator, run

npm install -g generator-mozu-app

And then, in any directory, you can create or modify your mozu.config.json environment file by running:

yo mozu-app --config



Type: String Required

The application key of the application, theme, or extension you are working on in Developer Center.


Type: Object Required

A context object to use to create a Mozu Node SDK client. It should include:

  • developerAccountId: a developer account ID. You can see your developer account ID in the Mozu Launchpad when you select which Dev Center to login to. This is required.
  • developerAccount: an object representing your user login. Unless you are supplying this information at the command line as described below, this is required. It should be an object with an emailAddress property containing your user email, as shown above. You can also supply a password here to avoid being prompted, but be careful not to put a plaintext password in your Gruntfile. You could, for instance, use process.env to assign the value of an environment variable.
  • baseUrl: a URL representing the Mozu environment. Unless you have special access to an internal preproduction Mozu environment, you don't need to provide this.


Type: Boolean Default value: false

The task will normally prompt you for your password and then store authentication tokens in your home directory using Multipass. It never stores passwords in plaintext. However, if you want to manage your authentication manually instead, you can remove this behavior by setting noStoreAuth to true.


Type: String Default value: 'upload'

A string value describing the type of sync action to take. The default is 'upload', which both creates and updates files. The full set of options is:

  • 'upload' -- create and/or update files in Developer Center
  • 'delete' -- delete files in Developer Center
  • 'deleteAll' -- delete all files in Developer Center
  • 'rename' -- rename files in Developer Center

The different actions use slightly different configuration, so you can think of them as different tasks, though they will share common options.


Use normal Grunt file specification formats, including globbing.

For the upload action, only a src is necessary. The dest doesn't make sense, since the file destination is Developer Center.

For the delete action, the files collection won't work. Grunt automatically filters the runtime files array for files that exist. The delete action is often run in the context of a file watch, so by the time the action runs, the relevant files don't exist anymore! For this reason, the delete action looks for an array of strings representing filenames under the property remove.

For the rename action, populate a files object with src/dest mappings of each file you want to rename. You will probably not configure this manually in your Gruntfile. You'll want to configure a grunt-contrib-watch adapter to do it dynamically.

For the deleteAll action, the files object is irrelevant. They're all doomed.


Type: Boolean Default value: false for the upload and rename actions, true for the delete and deleteAll actions

Some actions are destructive, such as delete and deleteAll, so this options serves as a safety measure: the task will only run if it was called directly from the command line, as in grunt mozusync:del, instead of as part of a grouped task, such as grunt or grunt build.


Type: Boolean Default value: false

This option applies to the upload action. If this is set to true, then the uploads will include a last modified date from your local file system. If you attempt to upload a file that is older than the one in Developer Center, the upload will fail. If it is set to false, then all uploads will override regardless of modified date.


Type: Boolean Default value: false

This option applies to the upload action. By default, this action will use checksums to determine if the local file and the remote file are identical, and will skip the upload if they are. Set this to true to override this behavior.

Authentication with command line arguments

By default, the task will pause Grunt execution and prompt the user to input a password in the terminal. If Grunt is running on a continuous integration server and/or you are using this task in an automated deployment, it would be more appropriate to supply a password as part of the scripted environment. You can provide username and password information as command-line arguments to Grunt instead.

Assuming that you have configured a mozusync task target called upload, as in the example above, you can supply the username and password like this:


Or, you can set the developerAccount.emailAddress in mozu.config.json and supply only the password:

grunt mozusync:upload:my_password_123

Note that you must run the mozusync task separately to use command-line authentication; you cannot run it as part of an aggregate task or default build, to avoid exposing password information to untrusted code. If mozusync is part of your default task, just configure a separate aggregate task that doesn't include mozusync, and configure your CI server to run that task, before running grunt mozusync separately with the provided authentication.

Using with grunt-contrib-watch and other watch plugins

The grunt-contrib-watch is useful for filesystem watching and synchronizing on save. One common problem is that the watch task can only run other tasks, and other tasks are not aware of which files changed, so by default they will run on all files. The task already checks with the Mozu App Dev APIs and compares file checksums to avoid unnecessary uploads, but the act of checking this for every file in your theme is itself slow.

Earlier versions of this plugin had "watch adapters", meant to hook directly in to grunt-contrib-watch. This had a number of disadvantages, so it has been removed. The new recommendation is to use the grunt-newer plugin in conjunction with grunt-contrib-watch and grunt-mozu-appdev-sync, which will optimize your workflow by only uploading necessary files.

An example optimal workflow:

    watch: {
      javascript: {
        files: [
        tasks: [
      sync: {
        files: [
        tasks: [


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.
