Laravel Installation

We will create laravel project using composer. So, please make sure your system should have composer installed. If not, may be this article will help you to Install composer in system.

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 Country -m

It will create two files –

  • Model – Country.php at /app/Models folder
  • Migration file – 2021_07_25_123805_create_countries_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 CreateCountriesTable extends Migration
     * Run the migrations.
     * @return void
    public function up()
        Schema::create('countries', function (Blueprint $table) {

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

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


namespace App\Models;

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

class Country extends Model
    use HasFactory;

    public $timestamps = false;

Run Migration

Next, we need to create table inside database.

$ php artisan migrate

Prepare JSON Data File

As we have table countries in which columns as id, name, sortname, phonecode.

We will take a JSON file in which properties of each object will be ID, Sortname, Name & Phonecode. Rest we need data into it.

When you will download the given file it will be in .txt format. Rename file into .json and place this countries-data.json file inside /public/data folder.

Open countries-data.json file, you should see –

Create Seeder

Next, we need to create a seeder file.

$ php artisan make:seeder CountrySeeder

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

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


namespace Database\Seeders;

use Illuminate\Database\Seeder;
use App\Models\Country;
use File;

class CountrySeeder extends Seeder
     * Run the database seeds.
     * @return void
    public function run()
        $json = File::get(public_path("data/countries-data.json"));
        $countries = json_decode($json);
        foreach ($countries->countries as $key => $value) {
                "sortname" => $value->sortname,
                "name" => $value->name,
                "phonecode" => $value->phoneCode
