JsonApiBundle For Symfony

JsonApiBundle is a Symfony bundle. It is the fastest way to generate API based on JsonApi using woohoolabs/yin Library.

Installing

1. Install symfony

   composer create-project symfony/skeleton YOUR_PROJECT
   

2. Install the maker bundle

   composer require symfony/maker-bundle --dev
   

3. Install the bundle

   composer require paknahad/jsonapi-bundle
   

4. Add below line to config/bundles.php

   Paknahad\JsonApiBundle\JsonApiBundle::class => ['all' => true],
   

Usage

1. Use below command to generate entities one by one:

   bin/console make:entity
   

   for example, Book and Author entity is as follows:

   class Book
   {
       /**
        * @ORM\Id()
        * @ORM\GeneratedValue()
        * @ORM\Column(type="integer")
        */
       private $id;
   
       /**
        * @ORM\Column(type="string", length=255)
        */
       private $title;
   
       /**
        * @ORM\Column(type="string", length=20, nullable=true)
        */
       private $isbn;
   
       /**
        * @ORM\ManyToMany(targetEntity="App\Entity\Author", inversedBy="books")
        */
       private $authors;
    
       ... 

   class Author
   {
       /**
        * @ORM\Id()
        * @ORM\GeneratedValue()
        * @ORM\Column(type="integer")
        */
       private $id;
   
       /**
        * @ORM\Column(type="string", length=255)
        * @Assert\NotBlank()
        * @Assert\Length(min=3)
        */
       private $name;
   
       /**
        * @ORM\ManyToMany(targetEntity="App\Entity\Book", mappedBy="authors")
        */
       private $books;
    
       ...

2. Generate CRUD API:

   bin/console make:api
   

3. You can find the generated "collection" for postman in the following path and then test the API:

   postman/api_collection.json
   

Features

1. Pagination

   http://example.com/books?page[number]=5&page[size]=30
   

2. Relationships

   http://example.com/books?include=authors
   

   multiple relationships

   http://example.com/books?include=authors.phones,publishers
   

3. Search

   This request will return all the books that author's name begin with hamid

   http://example.com/books?filter[authors.name]=hamid%
   

   Below line has additional condition: books which have "php" in their title.

   http://example.com/books?filter[title]=%php%&filter[authors.name]=hamid%
   

4. Validation

   Error on validating associations

   {
       "jsonapi": {
           "version": "1.0"
       },
       "errors": [
           {
               "detail": "Invalid value for this relation",
               "source": {
                   "pointer": "/data/relationships/authors",
                   "parameter": "1"
               }
           }
       ]
   }

   Validate attributes if you have defined validators on entities.

   {
       "jsonapi": {
           "version": "1.0"
       },
       "errors": [
           {
               "detail": "This value is too short. It should have 3 characters or more.",
               "source": {
                   "pointer": "/data/attributes/name",
                   "parameter": "h"
               }
           }
       ]
   }

5. Error handler

   • Internal server error (500)
   • Not found (404)
   • Access denied (403)
