Let’s get started.

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

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 & Migration

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

$ php artisan make:model BrowserStat -m

It will create two files –

Model – BrowserStat.php at /app/Models folder
Migration file – 2021_05_04_145928_create_browser_stats_table.php 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 CreateBrowserStatsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('browser_stats', function (Blueprint $table) {
            $table->id();
            $table->string("name", 30);
            $table->float("total_usage");
        });
    }

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

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

<?php

namespace App\Models;

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

class BrowserStat extends Model
{
    use HasFactory;

    public $timestamps = false;
}

Run Migration

Next, we need to create tables inside database.

$ php artisan migrate

This command will create tables inside database.

Create Data Seeder

Next, creating a seeder files to seed some dummy data for table.

Run this command to terminal –

$ php artisan make:seeder BrowserStatSeeder

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

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

<?php

namespace Database\Seeders;

use Illuminate\Database\Seeder;

use App\Models\BrowserStat;

class BrowserStatSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $data = [
            array(
                "name" => "Chrome",
                "total_usage" => 64.02
            ),
            array(
                "name" => "Firefox",
                "total_usage" => 12.55
            ),
            array(
                "name" => "IE",
                "total_usage" => 8.47
            ),
            array(
                "name" => "Safari",
                "total_usage" => 6.08
            ),
            array(
                "name" => "Edge",
                "total_usage" => 4.29
            ),
            array(
                "name" => "Others",
                "total_usage" => 4.59
            )
        ];

        BrowserStat::insert($data);
    }
}

Run Seeder File

Run this command to terminal.

$ php artisan db:seed --class=BrowserStatSeeder

It will create test data into database table.

Create Controller

Next, we need to create a controller file.

$ php artisan make:controller BrowserController

It will create a file BrowserController.php at /app/Http/Controllers folder.

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

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Models\BrowserStat;

class BrowserController extends Controller
{
    public function index()
    {
        $browsers = BrowserStat::all();

        $dataPoints = [];

        foreach ($browsers as $browser) {
            
            $dataPoints[] = [
                "name" => $browser['name'],
                "y" => floatval($browser['total_usage'])
            ];
        }

        return view("pie-chart", [
            "data" => json_encode($dataPoints)
        ]);
    }
}

Create Blade Layout File

Go to /resources/views folder and create a file with name pie-chart.blade.php

Open pie-chart.blade.php and write this complete code into it.

Create Route

Open web.php from /routes folder and add this route into it.

# Add this to header
use App\Http\Controllers\BrowserController;

//...

Route::get('browser-usage', [BrowserController::class, 'index']);

Application Testing

Run this command into project terminal to start development server,

php artisan serve

URL: http://127.0.0.1:8000/browser-usage
