Wizards Technologies' PHP REST API Library

A framework agnostic PHP library based on fractal to help you craft beautiful REST APIs.

Goals

The main goal is to provide an easy to use and powerful REST API library that seamlessly integrates with modern frameworks.

The paradigm reads as follow:

• A method will ask for a given resource (usually a controller), sending over an http request that we Parse to find standardized parameters. A resource is a data object, that you can fetch from a data store - as a collection or as an entry. Thoses resources can have relationships, can be filtered, can be modified, ....
• The library will fetch the resource(s) according to the given Object Manager (something like an orm, odm) and request
• It then transforms the data into standardized resource(s) given the provided Object Reader (there are many ways to configure resources, such as doctrine annotations, configuration files, ...)
• It sends the found resources to fractal with the appropriate Transformer for serialization on the given output format.

Installation

composer require wizards/rest-api

Usage

The library's conventions are based on the jsonapi ones.

Query Paramters

The RestQueryParser will expect those query parameters:

• Collection

  • sort
    • name to sort by ascending name
    • -name to sort by descending name
    • Example: ?sort=-date
  • filter to filter resources by values.
    • multiple values for filters should be provided coma-separated.
    • Example: ?filter[name]=dupont,dupond&filter[surname]=thomas
  • filteroperator
    • to change the default filter opetator from = to something else.
    • available operators: <, >, <=, >=, !=, in.
    • Example: ?filter[age]=18&filteroperator[age]=>=
  • include to include relationships data.
    • Example: /books?include=author,editor
  • limit: how many results you want to see by page.
  • page: the page number. Starts at 1.

• Single resource

  • include to include relationships data. Example: /books/1?include=author,editor

Examples

Plain ol' PHP

<?php

namespace App\Controller;

use Psr\Http\Message\ServerRequestInterface;
use WizardsRest\ObjectManager\ArrayObjectManager;
use WizardsRest\CollectionManager;
use WizardsRest\Provider;
use WizardsRest\Serializer;
use WizardsRest\ObjectReader\ArrayReader;
use WizardsRest\Paginator\ArrayPagerfantaPaginator;
use Symfony\Component\Routing\RouterInterface;
use WizardsRest\Transformer\ArrayTransformer;

Class BookController {
    private $source = [
        ['name' => 'Book 1', 'author' => 'Author 1', 'editor' => 'Editor 1'],
        ['name' => 'Book 2', 'author' => 'Author 2', 'editor' => 'Editor 2'],
    ];

    // Books controller. Somehow, this is called
    public function getBooks(RouterInterface $router, ServerRequestInterface $request) {
        // Fetch
        $objectManager = new ArrayObjectManager();
        $paginator = new ArrayPagerfantaPaginator($router);
        $collectionManager = new CollectionManager($paginator, $objectManager);
        $collection = $collectionManager->getPaginatedCollection($this->source, $request);

        // Transform
        $fractalManager = new \League\Fractal\Manager();
        $reader = new ArrayReader();
        $provider = new Provider(new ArrayTransformer(), $fractalManager, $reader);
        $resource = $provider->transform($collection, $request, null, 'books');

        // Serialize
        $serializer = new Serializer($fractalManager, 'https://mysite.com');
        return $serializer->serialize($resource, Serializer::SPEC_DATA_ARRAY, Serializer::FORMAT_ARRAY);
    }
}

Laravel

We are actively looking for laravel developers to support it !

Future plans

• Add more tests
• Add the sparse fieldset feature
• Add advanced filter operators such as like or between
• Optimize how the data are fetched from the source.
• Think about serialization groups.
