Community Sprinkles

One great thing about the Sprinkle system is its ability to wrap complete functionality inside a single package. This makes it a great tool to write your website isolated from the core UserFrosting code. It also means it's super easy to share sprinkles between projects... and with other members of the UserFrosting community! That's what we call a community sprinkle.

Finding Sprinkles

The best place to look for community sprinkles is on GitHub. We recommend tagging your community sprinkles with the userfrosting-sprinkle topic. This will make it easier for people to find your community sprinkle using GitHub search bar.

Distributing your Sprinkle

If you want to distribute your sprinkle, there's no real requirements that need to be met. You should at least make sure your sprinkle contains a valid composer.json file. This file is required to add any sort of class and PSR-4 definition to your sprinkle, so the chances are good you already have one. Make sure it contains up-to-date information, like your name and licence details, it's always welcome. Oh, and make sure the type key is defined as userfrosting-sprinkle in your sprinkles composer.json file !

You should also make sure your Sprinkle is up to date with the latest version of UserFrosting. Providing documentation and examples in a README file will encourage dev to use your sprinkle. If your sprinkle is interacting with the database, make sure your bundle a working migration with your sprinkle. That's pretty much it!

Sprinkles and Composer

When sharing a community sprinkle, we highly recommend publishing it on GitHub and adding it to Packagist. Since the app/sprinkles.json file is actually interpreted by Composer the same way a composer.json file is when running composer update, you can add any sprinkles available in the require key of your sprinkles.json file. For example:

    "require": {
        "foo/bar" : "^1.0.2"
    "base": [

When executing composer update with the above example, composer will automatically load foo/bar (version 1.0.2 or above) into your /app/sprinkles directory, as long as foo/bar is defined as userfrosting-sprinkle type in its own composer.json file. That's where the magic happens! This works just like any normal Composer dependency. You can also add non-Packagist sprinkles the same way you would do with any Composer dependencies, as long as the type is set to userfrosting-sprinkle in the repo composer.json. Otherwise, composer will load the package to app/vendor as usual. And don't forget to add bar to the list of sprinkle after!

Other sprinkles can also be defined as your sprinkle's dependencies in your own composer.json.

By default, Composer will load into app/sprinkles/ every dependency marked as a type userfrosting-sprinkle in a folder with the same name as the Packagist or GitHub repository inside app/sprinkles. In the above example, the foo/bar package would be downloaded to the app/sprinkles/bar directory. If you want to install your sprinkle in a different directory, you can use the installer-name key in your composer.json file.

For example, to install foo/bar as app/sprinkles/AwesomeBar/:

    "name": "foo/bar",
    "type": "userfrosting-sprinkle",
    "extra": {
        "installer-name": "AwesomeBar"

See Composer Installers documentation for more information on this.
