An Ethereal Package
Easy way to implement API formatted json responses.
Format:
{ "data": {...}, "errors": [], "success": true, "status_code": 200, "token": null }
Setup
Install:
composer require kevupton/laravel-json-response
Add the service provider to your app config:
\Kevupton\LaravelJsonResponse\Providers\LaravelJsonResponseProvider::class,
Add the middleware to your app\Http\Kernel.php
Either:
// Formats all responses in json. Catches errors listed in config and JsonResponseErrorExceptions Kevupton\LaravelJsonResponse\Middleware\OutputJsonResponse, // Extends the OutputJsonResponse to catch all errors, to keep the JSON output Kevupton\LaravelJsonResponse\Middleware\CatchAllExceptions,
Config
Publish the config by using the command:
php artisan vendor:publish
Examples
Example returning the data
Usage:
Route::get('test', function () { return ['hello' => true]; });
Output:
{ "data": { "hello": true }, "errors": [], "success": true, "status_code": 200 }
Example manipulating the JSON directly
You can also set data and tokens directly from this method.
Usage:
Route::get('test', function () { json_response()->error('This an example error message') ->setStatusCode(\Illuminate\Http\Response::HTTP_BAD_REQUEST); });
Output:
{ "data": [], "errors": [ "This an example error message" ], "success": false, "status_code": 400 }
Example returning a model
Models are added onto the data using snake_case.
Usage:
Route::get('test', function () { return \App\Models\TestModel::find(2); });
Output:
{ "data": { "test_model": { "id": 2 } }, "success": false, "status_code": 400 }
Example returning an Arrayable
Arrayable objects have toArray methods, which are merged with the data.
Usage:
Route::get('test', function () { return \App\Models\TestModel::paginate(); });
Output:
{ "data": { "current_page": 1, "data": [ { "id": 1 }, { "id": 2 }, ... ], "first_page_url": "http://url/api/test?page=1", "from": 1, "last_page": 3, "last_page_url": "http://url/api/test?page=3", "next_page_url": "http://url/api/test?page=2", "path": "http://url/api/test", "per_page": 10, "prev_page_url": null, "to": 10, "total": 24 }, "errors": [], "success": true, "status_code": 200 }
Example with validation errors
Usage:
Route::get('test', function () { throw new \Illuminate\Validation\ValidationException(\Validator::make([], ['test' => 'required'])); });
Output:
{ "data": [], "errors": { "test": [ "The test field is required." ] }, "success": false, "status_code": 422 }
Example Exception
NOTE: APP_DEBUG=true
will display a stack trace
Usage:
Route::get('test', function () { throw new Exception('test'); });
Output:
{ "data": [], "errors": [ "test message", { "file": "C:\\Users\\kevin\\Projects\\laravel\\vendor\\laravel\\framework\\src\\Illuminate\\Routing\\Route.php", "line": 172, "function": "runCallable", "class": "Illuminate\\Routing\\Route", "type": "->", "args": [] }, {...}, {...}, {...}, {...}, ... ], "success": false, "status_code": 500 }
Exception Handling
Exceptions can be caught by using the config file:
<?php use Illuminate\Database\Eloquent\ModelNotFoundException; use Illuminate\Http\Response; use Illuminate\Validation\ValidationException; use Kevupton\LaravelJsonResponse\JsonResponse; return [ 'exceptions' => [ /** * Show model not found when receiving this error */ ModelNotFoundException::class => 'Model not found', // OR ModelNotFoundException::class => ['NOT_FOUND', 'Model not found'], // OR ModelNotFoundException::class => [ 'error' => 'Model not found', // these are functions on the JsonResponse, being dynamically invoked 'setStatusCode' => Response::HTTP_NOT_FOUND ], /** * Add all the errors from the validation and continue */ ValidationException::class => function (ValidationException $e, JsonResponse $json) { $json ->mergeErrors($e->errors()) ->setStatusCode(Response::HTTP_UNPROCESSABLE_ENTITY); } ] ];
