If you wish to design a mobile application utilizing Laravel as a backend, some steps more or less are; Firstly, you need to set the appropriate structure for the Laravel project, the definition of the appropriate API routes, implementation of user’s authentication and integration of the Laravel backend project to a mobile frontend project. For the sake of clarity in this comprehensive tutorial, each step will be comprehensively explained concerning how you can use Laravel solutions in mobile app development. However, the goal of this work is to provide you with a non-strict recipe with clear and understandable step-by-step instructions on each part of the process, to maximize the usage of Laravel’s potential for mobile application development.
Why Choose Laravel for Mobile Application Backends?
Laravel’s Strengths for Mobile App Backends
Laravel is among the most used PHP frameworks in web development and has been pulled off for a good reason. When building the backend for a mobile app, Laravel offers several advantages:
- Robust API Support: Laravel comes with the framework to implement integrated RESTful API and as it is well known, REST API is the way how mobile applications and backends communicate with each other. This makes it easier for you to work on the development of the mobile app as you leave behind the complicated business of backend.
- Authentication: Sanctum and Passport are some of the Laravel tools that have made it easy to perform the authentication for APIs and tokens which are important for almost all mobile applications.
- Database Management: Laravel comes up with its own tool called Eloquent ORM that lays down a fluent, elegant and very easy to use interface for the database. Models, relationships, and even queries can be declared using a rather small amount of code, which makes the tool preferable for working with the data of your mobile app.
- Scalability and Flexibility: That way while still being perfect for launching your start-up, Laravel also allows you to scale up as the number of your users and levels of data interaction increase without a significant reduction in performance.
- Security: Laravel comes preloaded with security features like Cross-Site Request Forgery (CSRF) protection, SQL injection, and password hashed protection, all of which are useful when developing mobile apps for the safety of the user data.
Now, let’s look into how to build a mobile app with the help of Laravel in detail.
Step 1: Setting Up Your Laravel Project
Before you begin, ensure you have the following installed on your machine:
- PHP (7.4+ recommended)
- Composer (for managing PHP dependencies)
- A database like MySQL or PostgreSQL
- Laravel (via Composer)
1.1 Install Laravel
Start by installing a fresh Laravel project. Navigate to your project directory and run:
composer create-project –prefer-dist laravel/laravel mobile-backend
This will create a new Laravel project in a folder called mobile-backend.
1.2 Configure Your Database
After that, you can set up how your Laravel application should interact with your database. Open the .env file in the root of your project directory and set up your database credentials:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=mobile_app_db
DB_USERNAME=root
DB_PASSWORD=secret
Run the following command to test your database connection:
php artisan migrate
This should work without any issues if your database is correctly configured.
Step 2: Build the API for the Mobile App
Laravel is good for developing mobile application backends because that dictates that the backends need to have APIs which the mobile fronts can call. These APIs work CRUD on the data API where we can use these APIs depending on the features of that software.
2.1 Setting Up Routes
In Laravel, routes are all used to determine how HTTP application requests are processed. Most mobile applications communicate with the backend through APIs and therefore, you will be mostly dealing with the routes/api.php file.
Start by defining a route for testing:
use Illuminate\Support\Facades\Route;
Route::get(‘/test’, function () {
return response()->json([‘message’ => ‘Laravel API is working’]);
});
Now, if you access the route http://your-laravel-site/api/test, you’ll see a response indicating that the API is working.
2.2 Create the Models and Migrations
Next, let’s create a model for an entity in the mobile app. For example, let’s create a Product model that the app will manage.
Run the following command to generate the model and migration file:
php artisan make:model Product -m
This command generates a model (Product.php) and a migration file in the database/migrations folder.
Edit the migration file to define the structure of your products table. For example:
public function up()
{
Schema::create(‘products’, function (Blueprint $table) {
$table->id();
$table->string(‘name’);
$table->text(‘description’);
$table->decimal(‘price’, 8, 2);
$table->timestamps();
});
}
After editing the migration file, run the migration:
php artisan migrate
This will create the products table in your database.
2.3 Create Controller for API Endpoints
Next, generate a controller that will handle the logic for your API routes:
php artisan make:controller ProductController
In ProductController.php, implement methods to handle CRUD operations. Here’s an example for retrieving all products and creating a new product:
use App\Models\Product;
use Illuminate\Http\Request;
class ProductController extends Controller
{
public function index()
{
return response()->json(Product::all());
}
public function store(Request $request)
{
$validated = $request->validate([
‘name’ => ‘required|string’,
‘description’ => ‘required|string’,
‘price’ => ‘required|numeric’,
]);
$product = Product::create($validated);
return response()->json($product, 201);
}
}
2.4 Define API Routes
Finally, define the API routes in routes/api.php that will correspond to the controller methods:
use App\Http\Controllers\ProductController;
Route::get(‘products’, [ProductController::class, ‘index’]);
Route::post(‘products’, [ProductController::class, ‘store’]);
These routes will allow mobile applications to fetch and add products.
Step 3: Implement Authentication for Mobile Users
The goal of an exercise in a mobile application is to assign an authentication process to the user in order to limit access to some of the resources. Laravel provides two main options for API authentication: Laravel Sanctum Vs Laravel Passport. If we are going to have basic usage, the only access control we will be using is Sanctum, which is actually a much simpler version built for SPA and mobile apps.
3.1 Install Sanctum
To install Sanctum, run:
composer require laravel/sanctum
Publish Sanctum’s configuration files:
php artisan vendor:publish –provider=”Laravel\Sanctum\SanctumServiceProvider”
Add Sanctum’s middleware to your app/Http/Kernel.php file, inside the ‘api’ middleware group:
‘api’ => [
\Laravel\Sanctum\Http\Middleware\EnsureFrontendRequestsAreStateful::class,
‘throttle:api’,
\Illuminate\Routing\Middleware\SubstituteBindings::class,
],
3.2 Create Authentication Routes
In your routes/api.php, add routes for user registration, login, and token management. Here’s an example:
use App\Models\User;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Route;
Route::post(‘register’, function (Request $request) {
$request->validate([
‘name’ => ‘required|string’,
’email’ => ‘required|email|unique:users’,
‘password’ => ‘required|string|min:6’,
]);
$user = User::create([
‘name’ => $request->name,
’email’ => $request->email,
‘password’ => bcrypt($request->password),
]);
return response()->json($user);
});
Route::post(‘login’, function (Request $request) {
$request->validate([
’email’ => ‘required|email’,
‘password’ => ‘required|string’,
]);
if (Auth::attempt($request->only(’email’, ‘password’))) {
$user = Auth::user();
$token = $user->createToken(‘MobileAppToken’)->plainTextToken;
return response()->json([‘token’ => $token]);
}
return response()->json([‘message’ => ‘Invalid credentials’], 401);
});
Route::middleware(‘auth:sanctum’)->post(‘logout’, function () {
Auth::user()->tokens->delete();
return response()->json([‘message’ => ‘Logged out’]);
});
In this setup:
- Register creates a new user.
- Login authenticates a user and provides a token.
- Logout invalidates the user’s token.
3.3 Protect Routes with Authentication
For any routes that require authentication, add the auth:and how to config its sanctum middleware so that only authorized users can use the APIs. For example, you can protect the product routes like so:
Route::middleware(‘auth:sanctum’)->get(‘products’, [ProductController::class, ‘index’]);
Route::middleware(‘auth:sanctum’)->post(‘products’, [ProductController::class, ‘store’]);
Step 4: Testing the API
Once your backend is ready, you should test it using tools like Postman or Insomnia to simulate API requests.
- Testing Registration: Send a POST request to http://your-laravel-site/api/register with user details.
- Testing Login: Send a POST request to http://your-laravel-site/api/login with the user’s credentials to receive a token.
- Testing Protected Routes: Add the token in the Authorization header when accessing routes like /api/products.
Step 5: Connect the Mobile Frontend
At this stage of your application, your backend is built for a connection to a mobile frontend that could be created with React Native, Flutter or native applications. Here’s an outline of how to connect the mobile app with the backend:
- Mobile App Sends HTTP Requests: In React Native you could use libraries like Axios or fetch while for Flutter, there is a native http library to call the Laravel API.
- Handle Authentication: After login, the mobile app should pass the token received as a Bearer token in the request header for any of the protected API.
- Display Data: The information received from the backend of the mobile app (for instance, products list) should be used to display the UI.
Conclusion
Building a mobile application to hire offshore Laravel developers involves several key steps: when installing Laravel, creating databases and models, defining the API and implementing authentication, as well as testing the API. Sanctum for authentication, Eloquent for ORM, and routing for API are Laravel’s inbuilt for which it is perfect for the mobile app backends.
Once your backend is ready, integration with the mobile front-end using libraries like Axios or Flutter HTTP package will enable one to make it easy for users using the mobile App. In this tutorial you should learn how to implement a full-featured backend for your mobile application using Laravel.
