Download the PHP package spatie/fractalistic without Composer

A developer friendly wrapper around Fractal

Fractal is an amazing package to transform data before using it in an API. Unfortunately working with Fractal can be a bit verbose.

Using Fractal data can be transformed like this:

This package makes that process a tad easier:

There's also a very short syntax available to quickly transform data:

If you want to use this package inside Laravel, it's recommend to use laravel-fractal instead. That package contains a few more whistles and bells specifically targetted at Laravel users.

Install

You can pull in the package via composer:

Usage

In the following examples were going to use the following array as example input:

But know that any structure that can be looped (for instance a collection) can be used.

Let's start with a simple transformation.

This will return:

In all following examples it's assumed that you imported the Spatie\Fractalistic\Fractal at the top of your php file.

Instead of using a closure you can also pass a Transformer:

You can also pass the classname of the Transformer:

To make your code a bit shorter you could also pass the transform closure, class, or classname as a second parameter of the collection-method:

Want to get some sweet json output instead of an array? No problem!

A single item can also be transformed:

Using a serializer

Let's take a look again at the output of the first example:

Notice that data-key? That's part of Fractal's default behaviour. Take a look at Fractals's documentation on serializers to find out why that happens.

If you want to use another serializer you can specify one with the serializeWith-method. The Spatie\Fractalistic\ArraySerializer comes out of the box. It removes the data namespace for both collections and items.

You can also pass the serializer classname instead of an instantiation:

Changing the default serializer

You can change the default serializer by providing the classname or an instantiation of your favorite serializer in the config file.

Using includes

Fractal provides support for optionally including data on the relationships for the data you're exporting. You can use Fractal's parseIncludes which accepts a string or an array:

To improve readablity you can also use a function named include followed by the name of the include you want to... include:

Using excludes

Similar to includes Fractal also provides support for optionally excluding data on the relationships for the data you're exporting. You can use Fractal's parseExcludes which accepts a string or an array:

To improve readability you can also use a function named exclude followed by the name of the include you want to... exclude:

Including meta data

Fractal has support for including meta data. You can use addMeta which accepts one or more arrays:

This will return the following array:

Using pagination

Fractal provides a Laravel-specific paginator, IlluminatePaginatorAdapter, which accepts an instance of Laravel's LengthAwarePaginator and works with paginated Eloquent results. When using some serializers, such as the JsonApiSerializer, pagination data can be automatically generated and included in the result set:

Using a cursor

Fractal provides a simple cursor class, League\Fractal\Pagination\Cursor. You can use any other cursor class as long as it implements the League\Fractal\Pagination\CursorInterface interface. When using it, the cursor information will be automatically included in the result metadata:

Setting a custom resource name

Certain serializers wrap the array output with a data element. The name of this element can be customized:

Limit recursion

To increase or decrease the level of embedded includes you can use limitRecursion.

If you do not call limitRecursion a default value of 10 is used.

Quickly transform data with the short function syntax

You can also pass arguments to the fractal-function itself. The first arguments should be the data you which to transform. The second one should be a transformer or a closure that will be used to transform the data. The third one should be a serializer.
