json-api

Easy JSON:API integration.

Installation

Composer

composer require juliangut/json-api

symfony/yaml to parse yaml files

composer require symfony/yaml

Usage

Require composer autoload file

require './vendor/autoload.php';

use Jgut\JsonApi\Manager;
use Jgut\JsonApi\Configuration;
use Neomerx\JsonApi\Schema\Error;

$configuration = new Configuration([
    'sources' => ['/path/to/resource/files'],
]);

$jsonApiManager = new Manager($configuration);

// Get encoded errors
$jsonApiManager->encodeErrors(new Error());

// Get encoded resources
$jsonApiManager->encodeResources(new MyClass(), new ServerRequestInstance());

Configuration

• sources must be an array containing arrays of configurations to create MappingDriver objects:
  • type one of \Jgut\JsonApi\Mapping\Driver\DriverFactory constants: DRIVER_ATTRIBUTE, DRIVER_PHP, DRIVER_JSON, DRIVER_XML, DRIVER_YAML or DRIVER_ANNOTATION if no driver, defaults to DRIVER_ATTRIBUTE
  • path a string path or array of paths to where mapping files are located (files or directories) REQUIRED if no driver
  • driver an already created \Jgut\JsonApi\Mapping\Driver\DriverInterface object REQUIRED if no type AND path
• attributeName name of the PSR-7 Request attribute that will hold query parameters for resource encoding, defaults to 'JSON_API_query_parameters'
• schema class name implementing \Jgut\JsonApi\Schema\MetadataSchemaInterface (\Jgut\JsonApi\Schema\MetadataSchema by default)
• prefix prefix for generated URLs
• metadataResolver an instance of \Jgut\Mapping\Metadata\MetadataResolver. It is highly recommended to provide a PSR-16 cache to metadata resolver on production
• encodingOptions global encoding options, an instance of \Jgut\JsonApi\Encoding\OptionsInterface
• jsonApiVersion none by default
• jsonApiMeta optional global metadata

Middleware

Use PSR-15 middleware Jgut\JsonApi\Middleware\JsonApiMiddleware in order to validate request being a valid JSON:API specification request

use Jgut\JsonApi\Manager;
use Jgut\JsonApi\Middleware\JsonApiMiddleware;
use Psr\Http\Message\ResponseFactoryInterface;

/** @var ResponseFactoryInterface $responseFactory */
/** @var Manager $jsonApiManager */

$middleware = new JsonApiMiddleware($responseFactory, $jsonApiManager);

// Add the middleware to any PSR-15 compatible library/framework, such as Slim, Mezzio, etc 

Console command

use Symfony\Component\Console\Application;
use Jgut\Slim\PHPDI\Command\ListCommand;

/** @var \Slim\App $app */
$container = $app->getContainer();

$cli = new Application('Slim CLI');
$cli->add(new ListCommand($container));

$app->run();

List container definitions

List defined container definitions supporting searching

Resource mapping

Resources can be defined in two basic ways: by writing them down in definition files of various types or directly defined in attributes on classes

Attributes

ResourceObject (Class level)

Identifies each JSON:API resource. Its presence is mandatory in each resource class

Accepts an optional "name" that overrides default (class name with lowercase first letter)

use Jgut\JsonApi\Mapping\Attribute\ResourceObject;
use Jgut\JsonApi\Mapping\Attribute\ResourcePrefix;
use Jgut\JsonApi\Mapping\Attribute\ResourceSchema;

#[ResourceObject(
    name: 'company',
    prefix: 'resourcePrefix',
    schema: 'customSchemaClass',
    meta: ['meta1' => 'value'],
)]
class Company
{
}

• name, optional, resource name, lowercase first letter class name by default
• prefix, optional, resource url prefix when links are included
• schema, optional, class name implementing \Jgut\JsonApi\Schema\MetadataSchemaInterface. Override default one

Identifier (Property level)

The resource identifier

use Jgut\JsonApi\Mapping\Attribute\Getter;
use Jgut\JsonApi\Mapping\Attribute\Identifier;
use Jgut\JsonApi\Mapping\Attribute\ResourceObject;
use Jgut\JsonApi\Mapping\Attribute\Setter;

#[ResourceObject]
class Owner
{
    #[Identifier(
        name: 'identifier',
        getter: 'getIdentifier',
        setter: 'setIdentifier',
        meta: ['meta1' => 'value'],
    )]
    protected string $id;
}

• name, optional, identifier name, lowercase first letter property name by default
• getter, optional, method in the class that gives access to the property. By default, uppercase first letter property name prefixed by "is" for booleans or "get" for the rest of types
• setter, optional, method in the class that sets the value for the property, uppercase first letter property name prefixed by "set"
• meta, optional, list of optional array/value array of identifier metadata

Attribute (Property level)

A resource attribute

use Jgut\JsonApi\Mapping\Attribute\Attribute;
use Jgut\JsonApi\Mapping\Attribute\Getter;
use Jgut\JsonApi\Mapping\Attribute\ResourceObject;
use Jgut\JsonApi\Mapping\Attribute\Setter;

#[ResourceObject]
class Company
{
    #[Attribute(
        name: 'title',
        getter: 'getTitle',
        setter: 'setTitle',
        groups: ['view'],
    )]
    protected string $title;
}

• name, optional, attribute name, lowercase first letter property name by default
• getter, optional, method in the class that gives access to the property. By default, uppercase first letter property name prefixed by "is" for booleans or "get" for the rest of types
• setter, optional, method in the class that sets the value for the property, uppercase first letter property name prefixed by "set"
• groups, optional, array of groups to which the attribute belongs

Relationship (Property level)

A resource relationship

use Jgut\JsonApi\Mapping\Attribute\Relationship;
use Jgut\JsonApi\Mapping\Attribute\ResourceObject;

#[ResourceObject]
class Company
{
    #[Relationship(
        name: 'owner',
        getter: 'getOwner',
        setter: 'setOwner',
        groups: ['view'],
    )]
    protected Owner $companyOwner;
}

• name, optional, relationship name, lowercase first letter property name by default
• getter, optional, method in the class that gives access to the property. By default, uppercase first letter property name prefixed by "is" for booleans or "get" for the rest of types
• setter, optional, method in the class that sets the value for the property, uppercase first letter property name prefixed by "set"
• groups, optional, array of groups to which the relationship belongs

Links

use Jgut\JsonApi\Mapping\Attribute\Link;
use Jgut\JsonApi\Mapping\Attribute\LinkRelated;
use Jgut\JsonApi\Mapping\Attribute\LinkSelf;
use Jgut\JsonApi\Mapping\Attribute\ResourceObject;
use Jgut\JsonApi\Mapping\Attribute\Relationship;

#[ResourceObject]
#[LinkSelf(false)]
#[LinkRelated]
#[Link(
    href: 'http://...',
    title: 'example',
    meta: ['meta1' => 'value'],
)]
class Company
{
    #[Relationship]
    #[LinkSelf]
    #[LinkRelated(false)]
    #[Link(
        href: 'http://...',
        title: 'example',
        meta: ['meta1' => 'value'],
    )]
    protected Owner $companyOwner;
}

LinkSelf (Class level)

Determines whether self link is included in the response

LinkRelated (Class level)

Determines whether self link is included in the response when the resource is included as a relationship

Link (Class and Property level)

Adds as many custom link to the resource or field as needed

• href, required, href of the link
• title, optional, link title
• meta, optional, list of optional link metadata (see metadata section below)

Metadata

use Jgut\JsonApi\Mapping\Attribute\Attribute;
use Jgut\JsonApi\Mapping\Attribute\Meta;
use Jgut\JsonApi\Mapping\Attribute\Relationship;
use Jgut\JsonApi\Mapping\Attribute\ResourceObject;

#[ResourceObject]
#[Meta(key: 'meta1', value: 'value')]
class Company
{
    #[Identifier]
    #[Meta(key: 'meta2', value: 'value')]
    protected string $id;
    
    #[Relationship]
    #[Meta(key: 'meta3', value: 'value')]
    #[Meta(key: 'meta4', value: 'value')]
    protected Owner $owner;
}

There are two kinds of metadata:

Meta Attribute (Class and Property level)

Assign one or more metadata to a resource, identifier or relationship

• key, required, metadata key
• value, required, metadata value

Other metadata

Link attributes accept metadata as a key/value array

Definition files

Annotations

Annotations are deprecated and will be removed eventually. Use Attribute mapping when possible.

You need to require Doctrine's annotation package

composer require doctrine/annotations
