JSON-API Base

Basic application elements for JSON-API projects.

Offers means for quickly scaffolding JSON-API compliance for Laravel applications.

This does NOT provide the means to set up the API or the means for user authorisation.

Version Compatibility

Installation

Via Composer

$ composer require pixelindustries/laravel-jsonapi

Add the JsonApiServiceProvider to your config/app.php:

Pixelindustries\JsonApi\Providers\JsonApiServiceProvider::class,

Publish the configuration file.

php artisan vendor:publish

Exceptions

In your App\Exceptions\Handler, change the render() method like so:

<?php

    public function render($request, Exception $exception)
    {
        if (is_jsonapi_request() || $request->wantsJson()) {
            return jsonapi_error($exception);
        }
        
        // ...

This will render exceptions thrown for all JSON-API (and JSON) requests as JSON-API error responses.

Middleware

To enforce correct headers, add the Pixelindustries\JsonApi\Http|Middleware\JsonApiHeaders middleware to the middleware group or relevant routes. You can do this by adding it to your App\Http\Kernel class:

<?php
    protected $middlewareGroups = [
        'api' => [
            // ... 
            \Pixelindustries\JsonApi\Http\Middleware\RequireJsonApiHeader::class,
        ],
    ];

Note that this will block access to any consumers of your API that do not conform their HTTP header use to the JSON-API standard.

Documentation

Request Data

Request Query String Data

JSON-API suggests passing in filter and page data using GET parameters, such as:

{API URL}?filter[id]=13&page[number]=2

This package offers tools for accessing this information in a standardized way:

Using the jsonapi_query() global helper function. This returns the singleton instance of Pixelindustries\JsonApi\Support\Request\RequestParser.

<?php
    // Get the full filter data associative array.
    $filter = jsonapi_query()->getFilter();
    
    // Get a specific filter key value, if it is present (with a default fallback).
    $id = jsonapi_query()->getFilterValue('id', 0);
    
    // Get the page number.
    $page = jsonapi_query()->getPageNumber();

You can ofcourse also instantiate the request parser yourself to access these methods:

<?php
    // Using the interface binding ...
    $jsonapi = app(\Pixelindustries\JsonApi\Contracts\Support\Request\RequestQueryParserInterface::class);
    
    // Or by instantiating it manually ...
    $jsonapi = new \Pixelindustries\JsonApi\Support\Request\RequestQueryParser(request());
    
    // After this, the same methods are available
    $id = $jsonapi->getFilterValue('id');

Request Body Data

For PUT and POST requests with JSON-API formatted body content, a special FormRequest is provided to validate and access request body data (\Pixelindustries\JsonApi\Http\Requests\JsonApiRequest).

This class may be extended and used as any FormRequest class in Laravel.

There is also a global help function jsonapi_request(), that returns an instance of this class (and thus mimics Laravel's request()).

<?php
    // Get validated data for the current request
    $jsonApiType = jsonapi_request()->getType();
    $jsonApiId   = jsonapi_request()->getId();

Encoding

This package offers an encoder to generate valid JSON-API output for variable input content.

With some minor setup, it is possible to generate JSON output according to JSON-API specs for Eloquent models and errors.

Eloquent models, single, collected or paginated, will be serialized as JSON-API resources.

More information on encoding and configuring resources.

Custom Encoding & Transformation

To use your own transformers for specific class FQNs for the content to be encoded, map them in the jsonapi.transform.map configuration key:

<?php
    'map' => [
        \Your\ContentClassFqn\Here::class => \Your\TransformerClassFqn\Here::class,        
    ],

This mapping will return the first-matched for content using is_a() checks. More specific matches should be higher in the list.

As a last resort, you can always extend and/or rebind the Pixelindustries\JsonApi\Encoder\Factories\TransformerFactory to provide your own transformers based on given content type.
