How to Create API using Laravel

Step 1 − Visit the following URL and download composer to install it on your system.

https://getcomposer.org/download/

Step 2 − After the Composer is installed, check the installation by typing the Composer command in the command prompt as shown in the following screenshot.

Step 3 − Create a new directory anywhere in your system for your new Laravel project. After that, move to path where you have created the new directory and type the following command there to install Laravel.

composer create-project laravel/laravel api

Step 4 − The above command will install Laravel in the current directory. Start the Laravel service by executing the following command.

php artisan serve

Step 5 – Create database in PhpMyAdmin and configure with env file in laravel

Step 6 – Create Migration(tables)

php artisan make:migration create_employees_table

<?php

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateEmployeesTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('employees', function (Blueprint $table) {
            $table->id();
            $table->string('name');
            $table->string('address');
            $table->string('mobile');
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('employees');
    }
}

Step 7 – php artisan migrate

Step 8 – Create Controller

php artisan make:controller EmployeeController

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Employee;

class EmployeeController extends Controller
{
    public function index()
    {
        $employees = Employee::all();
        return response()->json($employees);
    }  
    public function store(Request $request)
    {
        $employees = new Employee([
            'name' => $request->input('name'),
            'address' => $request->input('address'),
            'mobile' => $request->input('mobile'),
        ]);
        $employees->save();
        return response()->json('Employee created!');
    }
    public function show($id)
    {
        $contact = Employee::find($id);
        return response()->json($contact);
    }
    public function update(Request $request, $id)
    {
       $employees = Employee::find($id);
       $employees->update($request->all());
       return response()->json('Employee updated');
    }
    public function destroy($id)
    {
        $employees = Employee::find($id);
        $employees->delete();
        return response()->json(' deleted!');
    }
}

Step 9 – Create model

php artisan make:model Employee

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Employee extends Model
{
    protected $table='employees';
    protected $primaryKey='id';
    protected $fillable=['name','address','mobile'];
    use HasFactory;
}

Step – 10 Crete Routes in api.php

<?php

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Route;
use App\Http\Controllers\EmployeeController;



Route::get('/employees',[App\Http\Controllers\EmployeeController::class, 'index']);

Route::post('/save',[App\Http\Controllers\EmployeeController::class, 'store']);

Route::put('/update/{id}',[App\Http\Controllers\EmployeeController::class, 'update']);

Route::delete('/delete/{id}',[App\Http\Controllers\EmployeeController::class, 'destroy']);

Route::middleware('auth:sanctum')->get('/user', function (Request $request) {
    return $request->user();
});

Now API created you can test on browser
