Here is the command to create a laravel project-

$ composer create-project --prefer-dist laravel/laravel blog

To start the development server of Laravel –

$ php artisan serve


Assuming laravel already installed inside your system.

Create Database & Connect

To create a database, either we can create via Manual tool of PhpMyadmin or by means of a mysql command.

CREATE DATABASE laravel_app;

To connect database with application, Open .env file from application root. Search for DB_ and update your details.


Create Model & Migration

Open project into terminal and run this command to create model & migration file.

$ php artisan make:model Post -m

It will create two files –

  • Model – Post.php at /app/Models folder
  • Migration file – 2021_07_25_123805_2021_08_10_120110_create_posts_table at /database/migrations folder.

Open Migration file and write this complete code into it.


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

class CreatePostsTable extends Migration
     * Run the migrations.
     * @return void
    public function up()
        Schema::create('posts', function (Blueprint $table) {
            $table->string("title", 50);

     * Reverse the migrations.
     * @return void
    public function down()

Open model file Post.php and write this complete code into it.


namespace App\Models;

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

class Post extends Model
    use HasFactory;

    public $timestamps = false;

Run Migration

Next, we need to create table inside database.

$ php artisan migrate

Create Factory

Next, we need to create a factory file in which we will use faker library which generates fake data.

$ php artisan make:factory PostFactory --model=Post

It will create a file PostFactory.php at /database/factories folder.

Open PostFactory.php and write this complete code into it.


namespace Database\Factories;

use App\Models\Post;
use Illuminate\Database\Eloquent\Factories\Factory;

class PostFactory extends Factory
     * The name of the factory's corresponding model.
     * @var string
    protected $model = Post::class;

     * Define the model's default state.
     * @return array
    public function definition()
        return [
            'title' => $this->faker->title,
            'description' => $this->faker->text,

Create Seeder

Next, we need to create a seeder file.

$ php artisan make:seeder PostSeeder

It will create a file PostSeeder.php at /database/seeders folder.

Open PostSeeder.php and write this complete code into it.


namespace Database\Seeders;

use Illuminate\Database\Seeder;
use App\Models\Post;

class PostSeeder extends Seeder
     * Run the database seeds.
     * @return void
    public function run()
