Usage

#API Responses

This used for manipulating API JSON responses for success/fail calls

  • You can simply use for like:
<?php

use InnoFlash\LaraStart\Traits\APIResponses;

class ClassName
{
    use APIResponses;
  • Usage on all your controllers
<?php

namespace App\Http\Controllers;

use InnoFlash\LaraStart\Traits\APIResponses;
...

class Controller extends BaseController
{
    use AuthorizesRequests, DispatchesJobs, ValidatesRequests;
    use APIResponses;
}

Calling the functions

$this->successMessege('{optional :message here}')

and this gets you a response with status 200

{
  "success": true,
  "message": "status message",
  "data": [] //optional
}

ExceptionsTrait

This is to override Laravel error logging do that we sent all type of errors to our API clients

  • You can simply set it up by using the ExceptionsTrait in your Exceptions\Handler class
<?php

namespace App\Exceptions;

use Exception;
use InnoFlash\LaraStart\Traits\ExceptionsTrait;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;

class Handler extends ExceptionHandler
{
    use ExceptionsTrait;
  • Now override the render function
    public function render($request, Exception $exception)
    {
        return $this->apiExceptions($request, $exception);
    }
  • This overrides all errors and format
{
    "exception": "Illuminate\\Validation\\ValidationException", //error-class
    "statusCode": 422,   //error-status-code
    "message": "The password field is required." //error-message
}

If you want the default error rendering

return $this->apiExceptions($request, $exception, true); //true triggers the default error

#AuthService

  • This one helps handle logging in and fetching the user access token.
  • Works really well with JWT

SETUP

In the .env file you will need to add JWT secret key. Run the command below to get the key into your .env file

php artisan jwt:secret

By default JWT tokens live for 60 minutes so if you want to alter the lifespan add the following in the .env file

JWT_TTL => time_in_minutes

Then in your AuthenticationController you will need to inject the AuthService class in it

use InnoFlash\LaraStart\Services\AuthService;

class AuthController extends Controller
{
    private $authService;
    public function __construct(AuthService $authService)
    {
        $this->authService = $authService;
    }

USAGE

  • This is how simple you will call when you need the our desired results
  • You can make the same call if you want login the user after registering
    function login(LoginRequest $request)
    {
        return $this->authService->attemptLogin();
    }

If you are using multi-auth you will need to pass the guard you are using for authentication

function login(LoginRequest $request)
    {
        return $this->authService->attemptLogin([], 'your-guard);
    }

OUTPUT

{
    "user": {
        "id": 1,
        "first_name": "first_name",
        "last_name": "last_name",
        "email": "email",
        "email_verified_at": "_date_"
    },
    "token": {
        "access_token": "~access token~",
        "expires_in": "expires_in",
        "type": "bearer"
    }
}

CUSTOMIZATION

If you want to customize the the results you need to publish the config file

php artisan vendor:publish --tag=larastart-config

and this copies the larastart.php into you config folder

  • Edit the file to suit your needs
return [
    /**
     * Replace this login resource with your own if you have it
     */
    'resource' => \InnoFlash\LaraStart\Http\Resources\User::class,

    /**
     * Sets the default limit for paginated items
     */
    'limit' => 15,

    /**
     * Sets the default guard you want to use in the auth service
     */
    'guard' => 'api',

    /**
     * Sets whether or not all CRUD ops should return json or object.
     */
    'return_object'       => false,
];

CRUD Service

This is meant to simplify the most CRUD operations and its best done by generating some service classes in the app/Services directory. The services handle basic

  • Create
  • Update
  • Delete
  • Select

SETUP

Just create run an artisan command to create the ServiceClass and customize all you want if the boilder plate is not sufficient for you

php artisan make:service {ServiceName} --model={ModelName}
  • Almost done, you now need to inject your service class into the controller as follows
class ModelController extends Controller
{
    private $modelService;
    function __construct(ModelService $modelService)
    {
        $this->modelService = $modelService;
    }

Alternatively you can inject the service directly into your controller functions.

  • If you are going to use the ModelService in more than one class ie. the controller (and you wanna use it in requests and resources and wherever) you will have to add the ModelService into the AppServiceProvider as a singleton so that the app does not have rerun querying the model
//your app/Providers/AppServiceProvider.php

public function register()
{
    $this->app->singleton(ModelService::class);
}

Good to go, now let`s see how to run crud functions here

Please note that for all CRUD Ops (except destroy) you can pass a boolean flag of true if you want to return the object and skip responding as JSON.

Also keep in mind that the services are wired in such a way that they can fetch route-model-bound models.

SELECT QUERY
    /**
     * How to get the selected model
     */
    return $this->modelService->getModel();

    /**
     * Query for multiple results
     *
     * You are still open to run default model query like
     */
    return Model::all();
DELETE QUERY
public function delete(DeleteRequest $request)
{
    /**
     * Since the service is injected into the controller it
     * knows exactly what model to target so calling destroy
     * automates a precise delete
     *
     * You can pass a custom delete message or leave as is
     */
    return $this->modelService->destroy('custom delete message');
}
UPDATE QUERY
public function update(UpdateRequest $request)
{
    /**
     * You just have to sent the right model id and the
     * service finds the model and updates the model
     *
     * $params is highly likely to be the validated input
     *
     * You can override the update success message by adding
     * a message param as a second param
     * return {
     *              success: true,
     *              message: 'model updated'
     *        }
     */
    return $this->modelService->update($params);
}
CREATE QUERY
public function create(CreateRequest $request)
{
    /**
     * the create method takes an array for params so we are just gonna
     * set the validated values from our request
     *
     * This return the a default response
     * {
     *      success: true,
     *      message: "model created"
     * }
     */
    return $this->modelService->create($request->validated());

    /**
     * You can override the output message by passing a second parameter
     */
    return $this->modelService->create($request->validated(), 'custom message');

    /**
     * If you want to get the created object you must add another boolean param and set it to true to get the object
     * This returns the object as is
     */
        return $this->modelService->create($request->validated(), 'custom message', true);
}
SPECIAL CREATE QUERY

Oftenly we would wanna create models based on a model they belong to. You will need to override the getParentRelationship() in the ModelService::class (overriding the CRUDService class method)

/**
     * Attaches a parent to the current model
     */
    function getParentRelationship()
    {
        /**
         * For example you want to create a comment for a post
         * You will need to initialize the post($parentObject)
         *  and call the relationship it has to the current model(relationshipToModel)
         */
        return [
            ParentModel::class, //parent model of the model to be created
            'relationshipName', //relationship name in parent model
            'foreign_key', //OPTIONAL fK in new model or default is used
        ];

        /**
         * Mainly i have been using to attach a relationship to the
         * authenticated user
         * If you already have the parent object call the relationship
         * for this as shown in the example below
         */
        return auth('guard')->user()->relationshipToModel();
    }

When the service is setup now you can do the create function

    public function create(CreateRequest $request)
    {
        //where $params is the validated input
        return $this->taskService->createFromParent($params, 'Task created!');
    }
