README

A simple and human-friendly library for api servers (php serving json).

It allows you to generate json output according to the JSON:API v1.1 standard, while being easy to understand for people without knowledge of the jsonapi standard.

The JSON:API standard makes it easy for clients to fetch multiple resources in one call and understand the relations between them. Read more about it at jsonapi.org.

Installation

Use Composer require to get the latest stable version:

composer require alsvanzelf/jsonapi

Upgrading from v1

If you used v1 of this library, see UPGRADE_1_TO_2.md on how to upgrade.

Getting started

A small resource example

use alsvanzelf\jsonapi\ResourceDocument;

$document = new ResourceDocument($type='user', $id=42);
$document->add('name', 'Zaphod Beeblebrox');
$document->add('heads', 2);
$document->sendResponse();

Which will result in:

{
	"jsonapi": {
		"version": "1.1"
	},
	"data": {
		"type": "user",
		"id": "42",
		"attributes": {
			"name": "Zaphod Beeblebrox",
			"heads": 2
		}
	}
}

A collection of resources

use alsvanzelf\jsonapi\CollectionDocument;

$document = new CollectionDocument();
$document->add('user', 42, ['name' => 'Zaphod Beeblebrox']);
$document->add('user', 1, ['name' => 'Ford Prefect']);
$document->add('user', 2, ['name' => 'Arthur Dent']);
$document->sendResponse();

Which will result in:

{
	"jsonapi": {
		"version": "1.1"
	},
	"data": [
		{
			"type": "user",
			"id": "42",
			"attributes": {
				"name": "Zaphod Beeblebrox"
			}
		},
		{
			"type": "user",
			"id": "1",
			"attributes": {
				"name": "Ford Prefect"
			}
		},
		{
			"type": "user",
			"id": "2",
			"attributes": {
				"name": "Arthur Dent"
			}
		}
	]
}

Turning an exception into jsonapi

use alsvanzelf\jsonapi\ErrorsDocument;

$exception = new Exception('That is not valid', 422);

$document = ErrorsDocument::fromException($exception);
$document->sendResponse();

Which will result in:

{
	"jsonapi": {
		"version": "1.1"
	},
	"errors": [
		{
			"status": "422",
			"code": "Exception",
			"meta": {
				"class": "Exception",
				"message": "That is not valid",
				"code": 422,
				"file": "README.md",
				"line": 107,
				"trace": []
			}
		}
	]
}

Examples for all kind of responses are in the /examples directory.

Features

This library supports v1.1 of the JSON:API specification.

It has support for generating & sending documents with:

• single resources
• resource collections
• to-one and to-many relationships
• errors (easily turning exceptions into jsonapi output)
• v1.1 extensions via profiles
• v1.1 @-members for JSON-LD and others

Also there's tools to help processing of incoming requests:

• parse request options (include paths, sparse fieldsets, sort fields, pagination, filtering)
• parse request documents for creating, updating and deleting resources and relationships

Next to custom extensions, the following official extensions are included:

• Cursor Pagination (example code, specification)

Plans for the future include:

• validate request options (#58)
• validate request documents (#57)
