A set of libs for building standardized JSON responses in CakePHP 3.x REST APIs

cakephp-jsonapi

Set of libraries for building standardized JSON responses in CakePHP 3.x REST APIs, _(*1)

WHY? I needed a consistent way to get REST reponses back from my API controllers. Additionally, there's a few basic setup steps that a Controller needs in order to properly handle JSON request/responses., _(*2)

HOW? Just add the JsonControllerTrait to turn any Controller into a JSON-friendly controller. Add the JsonResponseTrait to expose a number of response functions (detailed below)., _(*3)

Requirements

• PHP 5.4+
• CakePHP 3.x

Plugin Installation

1. Composer Install
2. Manual Install
   1. Loading the plugin in your app
   2. Setting up the namespace / autoloader

Composer Install

This plugin is on Packagist which means it can be easily installed with Composer., _(*4)

composer require cwbit/cakephp-jsonapi:dev-master

Then simply load the plugin normally in your config/bootstrap.php file, _(*5)

# in ../config/bootstrap.php - right after Plugin::load('Migrations') is fine!
Plugin::load('JsonApi');

Manual Install

You can also manually load this plugin in your App., _(*6)

:warning: Installing the plugin without the use of Composer is not officially supported. You do so at your own risk., _(*7)

loading the plugin in your app

Add the source code in this project into plugins/JsonApi, _(*8)

Then configure your App to actually load this plugin, _(*9)

# in ../config/bootstrap.php
Plugin::load('JsonApi');

setting up the namespace / autoloader

Tell the autoloader where to find your namespace in your composer.json file, _(*10)

    (..)
    "autoload": {
        "psr-4": {
           (..)
            "JsonApi\\": "./plugins/JsonApi/src"
        }
    },
    (..)

Then you need to issue the following command on the commandline, _(*11)

    php composer.phar dumpautoload

If you are unable to get composer autoloading to work, add 'autoload' => true line in your bootstrap.php Plugin::load(..) command (see loading section), _(*12)

Usage

The easiest way to get this set up is to simply add an Api namespace to your App. This way you can control exactly what your API does., _(*13)

To set up an Api namespace, add the following to your routes.php, _(*14)

# in routes.php
Router::prefix('api', function ($routes) {
    $routes->fallbacks('InflectedRoute');
});

Then, create an Api controller inside src/Controller/Api, _(*15)

<?php

namespace App\Controller\Api;

use App\Controller\AppController as Controller;
use JsonApi\Controller\JsonControllerTrait;
use JsonApi\Controller\JsonResponseTrait;

class AppController extends Controller
{

    use JsonControllerTrait;
    use JsonResponseTrait;

}

That's it! Now any of your controllers inside the Api namespace can automatically accept and respond to JSON calls, _(*16)

<?php
namespace App\Controller\Api;

use App\Controller\Api\AppController;

class FoosController extends AppController
{
    public function view()
    {
        # if no ID passed, respond with error 400
        if (!$this->request->data('id')) :
            return $this->respondWithBadRequest('Foo id is required');
        endif;

        # .. etc
    }
}

Response Methods

The JsonResponseTrait exposes the following response functions, _(*17)

• respondWith($statusCode, $message, $data)
• SUCCESS
• respondWithOK($message, $data) - Status 200 - OK
• respondWithCreated($message, $data) - Status 201 - CREATED
• respondWithNoContent($message, $data) - Status 204 - NO CONTENT
• REDIRECTION
• respondWithMovedPermanently($message, $data) - Status 301 - MOVED PERMANENTLY
• respondWithMovedTemporarily($message, $data) - Status 302 - MOVED TEMPORARILY
• respondWithSeeOther($message, $data) - Status 303 - SEE OTHER
• CLIENT ERROR
• respondWithBadRequest($message, $data) - Status 400 - BAD REQUEST
• respondWithUnauthorized($message, $data) - Status 401 - UNAUTHORIZED
• respondWithForbidden($message, $data) - Status 403 - FORBIDDEN
• respondWithNotFound($message, $data) - Status 404 - NOT FOUND
• respondWithMethodNotAllowed($message, $data) - Status 405 - METHOD NOT ALLOWED
• respondWithConflict($message, $data) - Status 409 - CONFLICT
• SERVER ERROR
• respondWithInternalServerError($message, $data) - Status 500 - INTERNAL SERVER ERROR
