How To Seed JSON Data in Laravel 10 Example Tutorial

Seeding a Laravel database with JSON data is an important step in web development since it allows you to populate your database with organised, predetermined data. Laravel, a versatile and resilient PHP framework, provides quick methods for seeding your database with JSON data, a popular and adaptable data storage format.

Database seeding is the process in which we feed test data to tables. We can insert data either using Faker library, manual data or means of some more data sources like CSV, JSON.

In this video, we will walk you through the process of seeding JSON data in Laravel 10, giving you the knowledge and tools you need to properly manage your database.

Let’s get started.

Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

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.

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

Create Model and Migration

Open project terminal and run this command to create model and migration file,

php artisan make:model Country -m

It will create two files –

• Model – Country.php inside /app/Models folder
• Migration file – xxx_create_countries_table inside /database/migrations folder.

Open file and write this complete code into it,

<?php

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

return new class extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up(): void
    {
        Schema::create('countries', function (Blueprint $table) {
            $table->increments('id');
            $table->string('sortname');
            $table->string('name');
            $table->string('phonecode');
        });
    }

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

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

<?php

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 migrate migration files.

php artisan migrate

This command will create tables inside database. It will create countries table in database.

Prepare JSON Data File (A Set of Data)

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

You have 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.

Create Laravel Data Seeder

Next, you need to create a seeder file.

php artisan make:seeder CountrySeeder

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

Open file and write this complete code into it.

<?php

namespace Database\Seeders;

use Illuminate\Database\Console\Seeds\WithoutModelEvents;
use Illuminate\Database\Seeder;
use App\Models\Country;
use File;

class CountrySeeder extends Seeder
{
    /**
     * Run the database seeds.
     */
    public function run()
    {
        //Country::truncate();

        $json = File::get(public_path("data/countries-data.json"));
        $countries = json_decode($json);
        
        foreach ($countries->countries as $key => $value) {
            Country::create([
                "sortname" => $value->sortname,
                "name" => $value->name,
                "phonecode" => $value->phoneCode
            ]);
        }

    }
}

Laravel Data Seeding

Open project terminal and run this artisan command

php artisan db:seed --class=CountrySeeder

It will seed countries data into table.

Successfully, you can see we have imported JSON data into database table using Laravel Data Seeding Concept.

That’s it.
