Installation of Laravel Application

Laravel Installation can be done in two ways.

  • Laravel Installer
  • By using composer

Laravel Installer

To install Laravel via Laravel installer, we need to install it’s installer first. We need to make use of composer for that.

$ composer global require laravel/installer

This command will install laravel installer at system. This installation is at global scope, so you type command from any directory at terminal. To verify type the given command –

$ laravel

This command will open a command palette of Laravel Installer.

To create ad install laravel project in system,

$ laravel new blog

With the name of blog a laravel project will be created at your specified path.

By using composer

Alternatively, we can also install Laravel by Composer command create-project. If your system doesn’t has Composer Installed, Learn Composer Installation Steps. Here is the complete command to create a laravel project-

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

After following these steps we can install a Laravel application into system.

To start the development server of Laravel –

$ php artisan serve

This command outputs –

Starting Laravel development server: http://127.0.0.1:8000

Assuming laravel already installed at 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.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravel_app
DB_USERNAME=root
DB_PASSWORD=root

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.

<?php

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->id();
            $table->string("title", 50);
            $table->text("description");
        });
    }

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

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

<?php

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.

<?php

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.

<?php

namespace Database\Seeders;

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

class PostSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Post::factory()->count(50)->create();
    }
}

Data Seeding

Open project into terminal and run this artisan command

$ php artisan db:seed --class=PostSeeder

It will seed countries data into table.
