## Installation
Use [Composer](https://getcomposer.org) to install the package:
```
composer require nilportugues/laravel5-json-api
```
Now run the following artisan command:
```
php artisan vendor:publish
```
## Configuration (Laravel 5 & Lumen)
For the sake of having a real life example, this configuration will guide you on how to set up **7 end-points** for two resources, `Employees` and `Orders`.
Both `Employees` and `Orders` resources will be **Eloquent** models, being related one with the other.
Furthermore, `Employees`will be using an Eloquent feature, `appended fields` to demonstrate how it is possible to make the most of Eloquent and this package all together.
### Configuration for Laravel 5
#### Step 1: Add the Service Provider
Open up `config/app.php` and add the following line under `providers` array:
```php
'providers' => [
//...
NilPortugues\Laravel5\JsonApi\Laravel5JsonApiServiceProvider::class,
],
```
#### Step 2: Defining routes
We will be planning the resources ahead its implementation. All routes require to have a name.
This is how our `app/Http/routes.php` will look:
```php
'Api'], function() {
Route::resource('employees', 'EmployeesController');
Route::get(
'employees/{employee_id}/orders', [
'as' => 'employees.orders',
'uses' => 'EmployeesController@getOrdersByEmployee'
]);
});
//...
```
#### Step 3: Definition
First, let's define the Models for `Employees` and `Orders` using Eloquent.
**Employees (Eloquent Model)**
```php
hasMany(Orders::class, 'employee_id')->limit(10);
}
/**
* @return string
*/
public function getFullNameAttribute()
{
return $this->first_name.' '.$this->last_name;
}
}
```
**Employees SQL**
```sql
CREATE TABLE `employees` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`company` varchar(50) DEFAULT NULL,
`last_name` varchar(50) DEFAULT NULL,
`first_name` varchar(50) DEFAULT NULL,
`email_address` varchar(50) DEFAULT NULL,
`job_title` varchar(50) DEFAULT NULL,
`business_phone` varchar(25) DEFAULT NULL,
`home_phone` varchar(25) DEFAULT NULL,
`mobile_phone` varchar(25) DEFAULT NULL,
`fax_number` varchar(25) DEFAULT NULL,
`address` longtext,
`city` varchar(50) DEFAULT NULL,
`state_province` varchar(50) DEFAULT NULL,
`zip_postal_code` varchar(15) DEFAULT NULL,
`country_region` varchar(50) DEFAULT NULL,
`web_page` longtext,
`notes` longtext,
`attachments` longblob,
PRIMARY KEY (`id`),
KEY `city` (`city`),
KEY `company` (`company`),
KEY `first_name` (`first_name`),
KEY `last_name` (`last_name`),
KEY `zip_postal_code` (`zip_postal_code`),
KEY `state_province` (`state_province`)
) ENGINE=InnoDB AUTO_INCREMENT=10 DEFAULT CHARSET=utf8;
INSERT INTO `employees` (`id`, `company`, `last_name`, `first_name`, `email_address`, `job_title`, `business_phone`, `home_phone`, `mobile_phone`, `fax_number`, `address`, `city`, `state_province`, `zip_postal_code`, `country_region`, `web_page`, `notes`, `attachments`)
VALUES
(10, 'Acme Industries', 'Smith', 'Mike', '[email protected]', 'Horticultarlist', '0118 9843212', NULL, NULL, NULL, '343 Friary Road', 'Manchester', 'Lancs.', 'M3 3DL', 'United Kingdom', NULL, NULL, NULL);
```
**Orders (Eloquent Model)**
```php
belongsTo(Employees::class, 'employee_id');
}
}
```
**Orders SQL**
```sql
CREATE TABLE `orders` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`employee_id` int(11) DEFAULT NULL,
`customer_id` int(11) DEFAULT NULL,
`order_date` datetime DEFAULT NULL,
`shipped_date` datetime DEFAULT NULL,
`shipper_id` int(11) DEFAULT NULL,
`ship_name` varchar(50) DEFAULT NULL,
`ship_address` longtext,
`ship_city` varchar(50) DEFAULT NULL,
`ship_state_province` varchar(50) DEFAULT NULL,
`ship_zip_postal_code` varchar(50) DEFAULT NULL,
`ship_country_region` varchar(50) DEFAULT NULL,
`shipping_fee` decimal(19,4) DEFAULT '0.0000',
`taxes` decimal(19,4) DEFAULT '0.0000',
`payment_type` varchar(50) DEFAULT NULL,
`paid_date` datetime DEFAULT NULL,
`notes` longtext,
`tax_rate` double DEFAULT '0',
`tax_status_id` tinyint(4) DEFAULT NULL,
`status_id` tinyint(4) DEFAULT '0',
PRIMARY KEY (`id`),
KEY `customer_id` (`customer_id`),
KEY `employee_id` (`employee_id`),
KEY `id` (`id`),
KEY `shipper_id` (`shipper_id`),
KEY `tax_status` (`tax_status_id`),
KEY `ship_zip_postal_code` (`ship_zip_postal_code`),
KEY `fk_orders_orders_status1` (`status_id`),
CONSTRAINT `fk_orders_employees1` FOREIGN KEY (`employee_id`) REFERENCES `employees` (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION
) ENGINE=InnoDB AUTO_INCREMENT=82 DEFAULT CHARSET=utf8;
INSERT INTO `orders` (`id`, `employee_id`, `customer_id`, `order_date`, `shipped_date`, `shipper_id`, `ship_name`, `ship_address`, `ship_city`, `ship_state_province`, `ship_zip_postal_code`, `ship_country_region`, `shipping_fee`, `taxes`, `payment_type`, `paid_date`, `notes`, `tax_rate`, `tax_status_id`, `status_id`)
VALUES
(82, 10, NULL, '2015-03-12 00:00:00', '2015-03-12 00:00:00', NULL, NULL, '43, Borrowed Drive', 'New Oreleans', 'Louisiana', '4322', 'USA', 1.4000, 0.0000, NULL, NULL, NULL, 0, NULL, 0);
```
Follow up, we'll be creating Transformers. One Transformer is required for each class and it must implement the `\NilPortugues\Api\Mappings\JsonApiMapping` interface.
We will be placing these files at `app/Model/Api`:
**EmployeesTransformer**
```php
'surname',
];
}
/**
* List of properties in the class that will be ignored by the mapping.
*
* @return array
*/
public function getHideProperties()
{
return [
'attachments'
];
}
/**
* Returns an array of properties that are used as an ID value.
*
* @return array
*/
public function getIdProperties()
{
return ['id'];
}
/**
* Returns a list of URLs. This urls must have placeholders
* to be replaced with the getIdProperties() values.
*
* @return array
*/
public function getUrls()
{
return [
'self' => ['name' => 'employees.show', 'as_id' => 'id'],
'employees' => ['name' => 'employees.index'],
'employee_orders' => ['name' => 'employees.orders', 'as_id' => 'id']
];
}
/**
* Returns an array containing the relationship mappings as an array.
* Key for each relationship defined must match a property of the mapped class.
*
* @return array
*/
public function getRelationships()
{
return [];
}
}
```
Same goes for `Orders`, these files will also be placed at `app/Model/Api`:
**OrdersTransformer**
```php
['name' => 'orders.show', 'as_id' => 'id'],
'employee' => ['name' => 'employees.show', 'as_id' => 'employee_id'],
];
}
/**
* {@inheritDoc}
*/
public function getRelationships()
{
return [];
}
/**
* List the fields that are mandatory in a persitence action (POST/PUT).
* If empty array is returned, all fields are mandatory.
*/
public function getRequiredProperties()
{
return [];
}
}
```
#### Step 4: Usage
Create file `config/jsonapi.php`. This file should return an array returning all the class mappings.
```php
### Configuration for Lumen
#### Step 1: Add the Service Provider
Open up `bootstrap/app.php`and add the following lines before the `return $app;` statement:
```php
$app->register(\NilPortugues\Laravel5\JsonApi\Laravel5JsonApiServiceProvider::class);
$app->configure('jsonapi');
```
Also, enable Facades by uncommenting:
```php
$app->withFacades();
```
#### Step 2: Defining routes
We will be planning the resources ahead its implementation. All routes require to have a name.
This is how our `app/Http/routes.php` will look:
```php
group(
['namespace' => 'Api'], function($app) {
$app->get(
'employees', [
'as' => 'employees.index',
'uses' =>'EmployeesController@index'
]);
$app->post(
'employees', [
'as' => 'employees.store',
'uses' =>'EmployeesController@store'
]);
$app->get(
'employees/{employee_id}', [
'as' => 'employees.show',
'uses' =>'EmployeesController@show'
]);
$app->put(
'employees/{employee_id}', [
'as' => 'employees.update',
'uses' =>'EmployeesController@update'
]);
$app->patch(
'employees/{employee_id}', [
'as' => 'employees.patch',
'uses' =>'EmployeesController@update'
]);
$app->delete(
'employees/{employee_id}', [
'as' => 'employees.destroy',
'uses' =>'EmployeesController@destroy'
]);
$app->get(
'employees/{employee_id}/orders', [
'as' => 'employees.orders',
'uses' => 'EmployeesController@getOrdersByEmployee'
]);
}
);
//...
```
#### Step 3: Definition
Same as Laravel 5.
#### Step 4: Usage
Same as Laravel 5.
## JsonApiController
Whether it's Laravel 5 or Lumen, usage is exactly the same.
Let's create a new controller that extends the `JsonApiController` provided by this package, as follows:
**Lumen users must extends from `LumenJsonApiController` not `JsonApiController`**.
```php
getPage();
if (!$page->size()) {
$page->setSize(10); //Default elements per page
}
$resource = new ListResource(
$this->serializer,
$page,
$apiRequest->getFields(),
$apiRequest->getSort(),
$apiRequest->getIncludedRelationships(),
$apiRequest->getFilters()
);
$totalAmount = function() use ($request) {
$id = (new Orders())->getKeyName();
return Orders::query()
->where('employee_id', '=', $request->employee_id)
->get([$id])
->count();
};
$results = function() use ($request) {
return EloquentHelper::paginate(
$this->serializer,
Orders::query()
->where('employee_id', '=', $request->employee_id)
)->get();
};
$uri = route('employees.orders', ['employee_id' => $request->employee_id]);
return $resource->get($totalAmount, $results, $uri, Orders::class);
}
}
```
And you're ready to go. Yes, it is **THAT** simple!
## Examples: Consuming the API
### GET
This is the output for `EmployeesController@getAction` being consumed from command-line method issuing: `curl -X GET "http://localhost:9000/employees/1"`.
**Output:**
```
HTTP/1.1 200 OK
Cache-Control: private, max-age=0, must-revalidate

},
"employee_orders": {
"href": "http://localhost:9000/employees/1/orders"
}
},
"jsonapi": {
"version": "1.0"
}
}
```
### POST
POST requires all member attributes to be accepted, even those hidden by the mapper.
For instance, `attachments` member was hidden, but it is required, so it needs to be passed in with a valid value. On the other hand, `full_name` member value must not be passed in as an attribute or resource creation will fail.
Passing and `id` is optional and will be used instead of a server-side generated value if provided.
Sending the following data to the server using `POST`to the following URI `http://localhost:9000/employees`:
```json
{
"data": {
"type": "employee",
"attributes": {
"company": "NilPortugues.com",
"surname": "Portugués",
"first_name": "Nil",
"email_address": "[email protected]",
"job_title": "Web Developer",
"business_phone": "(123)555-0100",
"home_phone": "(123)555-0102",
"mobile_phone": null,
"fax_number": "(123)555-0103",
"address": "Plaça Catalunya 1",
"city": "Barcelona",
"state_province": "Barcelona",
"zip_postal_code": "08028",
"country_region": "Spain",
"web_page": "http://nilportugues.com",
"notes": null,
"attachments": null
}
}
}
```
Will produce:
```
HTTP/1.1 201 Created
Cache-Control: private, max-age=0, must-revalidate
Content-type: application/vnd.api+json
Location: http://localhost:9000/employees/10
```
Notice how 201 HTTP Status Code is returned and Location header too. Also `attachments` is not there anymore, and `full_name` was displayed.
```json
{
"data": {
"type": "employee",
"id": "10",
"attributes": {
"company": "NilPortugues.com",
"surname": "Portugués",
"first_name": "Nil",
"email_address": "[email protected]",
"job_title": "Web Developer",
"business_phone": "(123)555-0100",

}
}
},
"links": {
"employees": {
"href": "http://localhost:9000/employees"
},
"employee_orders": {
"href": "http://localhost:9000/employees/10/orders"
}
},
"jsonapi": {
"version": "1.0"
}
}
```
### PUT
PUT requires all member attributes to be accepted, just like POST.
For the sake of this example, we'll just send in a new `job_title` value, and keep everything else exactly the same.
It's important to notice this time we are required to pass in the `id`, even if it has been passed in by the URI, and of course the `id` values must match. Otherwise it will fail.
Sending the following data to the server using `PUT`to the following URI `http://localhost:9000/employees/10`:
```json
{
"data": {
"type": "employee",
"id": 10,
"attributes": {
"company": "NilPortugues.com",
"surname": "Portugués",
"first_name": "Nil",
"email_address": "[email protected]",
"job_title": "Full Stack Web Developer",
"business_phone": "(123)555-0100",
"home_phone": "(123)555-0102",
"mobile_phone": null,
"fax_number": "(123)555-0103",
"address": "Plaça Catalunya 1",
"city": "Barcelona",
"state_province": "Barcelona",
"zip_postal_code": "08028",
"country_region": "Spain",
"web_page": "http://nilportugues.com",
"notes": null,
"attachments": null
}
}
}
```
Will produce:
```
HTTP/1.1 200 OK
Cache-Control: private, max-age=0, must-revalidate
Content-type: application/vnd.api+json
```
```json
{
"data": {
"type": "employee",
"id": "10",
"attributes": {
"company": "NilPortugues.com",
"surname": "Portugués",
"first_name": "Nil",
"email_address": "[email protected]",
"job_title": "Full Stack Web Developer",
"business_phone": "(123)555-0100",
"home_phone": "(123)555-0102",
"mobile_phone": null,
"fax_number": "(123)555-0103",
"address": "Plaça Catalunya 1",
"city": "Barcelona",
"state_province": "Barcelona",
"zip_postal_code": "08028",
"country_region": "Spain",
"web_page": "http://nilportugues.com",
"notes": null,
"full_name": "Nil Portugués"
},
"links": {
"self": {
"href": "http://localhost:9000/employees/10"
},
"employee_orders": {
"href": "http://localhost:9000/employees/10/orders"
}
}
},
"included": [],
"links": {
"employees": {
"href": "http://localhost:9000/employees"
},
"employee_orders": {
"href": "http://localhost:9000/employees/10/orders"
}
},
"jsonapi": {
"version": "1.0"
}
}
```
### PATCH
PATCH allows partial updates, unlike PUT.
We are required to pass in the `id` member, even if it has been passed in by the URI, and of course the `id` values must match. Otherwise it will fail.
For instance, sending the following data to the server using the following URI `http://localhost:9000/employees/10`:
```json
{
"data": {
"type": "employee",
"id": 10,
"attributes": {
"email_address": "[email protected]"
}
}
}
```
Will produce:
```
HTTP/1.1 200 OK
Cache-Control: private, max-age=0, must-revalidate
Content-type: application/vnd.api+json
```
```json
{
"data": {
"type": "employee",
"id": "10",
"attributes": {
"company": "NilPortugues.com",
"surname": "Portugués",
"first_name": "Nil",
"email_address": "[email protected]",
"job_title": "Full Stack Web Developer",
"business_phone": "(123)555-0100",
"home_phone": "(123)555-0102",
"mobile_phone": null,
"fax_number": "(123)555-0103",
"address": "Plaça Catalunya 1",
"city": "Barcelona",
"state_province": "Barcelona",
"zip_postal_code": "08028",
"country_region": "Spain",
"web_page": "http://nilportugues.com",
"notes": null,
"full_name": "Nil Portugués"
},
"links": {
"self": {
"href": "http://localhost:9000/employees/10"
},
"employee_orders": {
"href": "http://localhost:9000/employees/10/orders"
}
}
},
"included": [],
"links": {
"employees": {
"href": "http://localhost:9000/employees"
},
"employee_orders": {
"href": "http://localhost:9000/employees/10/orders"
}
},
"jsonapi": {
"version": "1.0"
}
}
```
### DELETE
DELETE is the easiest method to use, as it does not require body. Just issue a DELETE to `http://localhost:9000/employees/10/` and `Employee` with `id 10` will be gone.
It will produce the following output:
```
HTTP/1.1 204 No Content
Cache-Control: private, max-age=0, must-revalidate
Content-type: application/vnd.api+json
```
And notice how response will be empty:
```
```
## GET Query Params: include, fields, sort and page
According to the standard, for GET method, it is possible to:
- Show only those fields requested using `fields`query parameter.
- &fields[resource]=field1,field2
For instance, passing `/employees/10?fields[employee]=company,first_name` will produce the following output:
```json
{
"data": {
"type": "employee",
"id": "10",
"attributes": {
"company": "NilPortugues.com",
"first_name": "Nil"
},
"links": {
"self": {
"href": "http://localhost:9000/employees/10"
},
"employee_orders": {
"href": "http://localhost:9000/employees/10/orders"
}
}
},
"links": {
"employees": {
"href": "http://localhost:9000/employees"
},
"employee_orders": {
"href": "http://localhost:9000/employees/10/orders"
}
},
"jsonapi": {
"version": "1.0"
}
}
```
- Show only those `include` resources by passing in the relationship between them separated by dot, or just pass in list of resources separated by comma.
- &include=resource1
- &include=resource1.resource2,resource2.resource3
For instance, `/employees?include=order` will only load order type data inside `include` member, but `/employees?include=order.employee` will only load those orders related to the `employee` type.
- Sort results using `sort` and passing in the member names of the main resource defined in `data[type]` member. If it starts with a `-` order is `DESCENDING`, otherwise it's `ASCENDING`.
- &sort=field1,-field2
- &sort=-field1,field2
For instance: `/employees?sort=surname,-first_name`
- Pagination is also defined to allow doing page pagination, cursor pagination or offset pagination.
- &page[number]
- &page[limit]
- &page[cursor]
- &page[offset]
- &page[size]
For instance: `/employees?page[number]=1&page[size]=10`
## POST/PUT/PATCH with Relationships
The JSON API allows resource creation and modification and passing in `relationships` that will create or alter existing resources too.
Let's say we want to create a new `Employee` and pass in its first `Order`too.
This could be done issuing 2 `POST` to the end-points (one for Employee, one for Order) or pass in the first `Order` as a `relationship` with our `Employee`, for instance:
```json
{
"data": {
"type": "employee",
"attributes": {
"company": "Northwind Traders",
"surname": "Giussani",
"first_name": "Laura",
"email_address": "[email protected]",
"job_title": "Sales Coordinator",
"business_phone": "(123)555-0100",
"home_phone": "(123)555-0102",
"mobile_phone": null,
"fax_number": "(123)555-0103",
"address": "123 8th Avenue",
"city": "Redmond",
"state_province": "WA",
"zip_postal_code": "99999",
"country_region": "USA",
"web_page": "http://northwindtraders.com",
"notes": "Reads and writes French.",
"full_name": "Laura Giussani"
},
"relationships": {
"order": {
"data": [
{
"type": "order",
"attributes": {
"customer_id": "28",
"order_date": "2006-05-11 00:00:00",
"shipped_date": "2006-05-11 00:00:00",
"shipper_id": "3",
"ship_name": "Amritansh Raghav",
"ship_address": "789 28th Street",
"ship_city": "Memphis",
"ship_state_province": "TN",
"ship_zip_postal_code": "99999",
"ship_country_region": "USA",
"shipping_fee": "10.0000",
"taxes": "0.0000",
"payment_type": "Check",
"paid_date": "2006-05-11 00:00:00",
"notes": null,
"tax_rate": "0",
"tax_status_id": null,
"status_id": "0"
}
}
]
}
}
}
}
```
Due to the existance of this use case, we'll have to ajust our Controller implementation overwriting some methods provided by the **JsonApiController**: `createResourceCallable`, `updateResourceCallable` and `patchResourceCallable`.
Here's how it would be done for `createResourceCallable`.
```php
$model->getKey()]);
Orders::create($attributes);
}
}
};
return function (array $data, array $values, ErrorBag $errorBag) use ($createOrderResource) {
$attributes = [];
foreach ($values as $name => $value) {
$attributes[$name] = $value;
}
if (!empty($data['id'])) {
$attributes[$this->getDataModel()->getKeyName()] = $values['id'];
}
DB::beginTransaction();
try {
$model = $this->getDataModel()->create($attributes);
$createOrderResource($model, $data);
DB::commit();
return $model;
} catch(\Exception $e) {
DB::rollback();
$errorBag[] = new Error('creation_error', 'Resource could not be created');
throw $e;
}
};
}
}
```
It is important, in order to use Transactions, do define in `Eloquent` models the `$fillable` values.
Here's how `Employees` and `Orders` look like with `$fillable` defined.
**Employees (Eloquent Model) with $fillable**
```php
hasMany(Orders::class, 'employee_id')->limit(10);
}
/**
* @return string
*/
public function getFullNameAttribute()
{
return $this->first_name.' '.$this->last_name;
}
}
```
**Orders (Eloquent Model) with $fillable**
```php
belongsTo(Employees::class, 'employee_id');
}
}
```
## Custom Response Headers
Adding custom response headers can be done for multiple reasons: *versioning, setting expire headers, caching, setting private or public the served content...*
In order to do this, it's as simple as overwriting the JsonApiController `addHeaders` method. For instance, let's use the EmployeeController as an example:
```php
headers->set('X-API-Version', '1.0');
$response->setPublic();
$response->setMaxAge(60);
$response->setSharedMaxAge(60);
return $response;
}
}
```
Now all supported actions will include the added custom headers.
# Common Errors and Solutions
### "Undefined index: @type"
This usually happens because you did not write the namespace of your `Mapping` in `config/jsonapi.php`.
Double check, if missing, add it and refresh the resource. It should be gone!
