This guide walks you through the process of building a Laravel 8 application that uses Livewire and PowerGrid DataTable.

What You Will build

You will build a Laravel application with quick datatable fully configurable.

What You Need

• A favorite text editor or IDE
• PHP >= 7.3
• Composer
• Node.js
• Npm

Setup A New Project

Create a new Laravel project by using Composer:

composer create-project laravel/laravel laravel-8-livewire-powergrid-datatable
cd laravel-8-livewire-powergrid-datatable
php artisan serve

Installing Livewire

composer require livewire/livewire

Installing PowerGrid

composer require power-components/livewire-powergrid

Installing Tailwind

PowerGrid use Tailwind or Bootstrap to style the datatable, in this tutorial we use tailwind.

npm install -D tailwindcss@latest postcss@latest autoprefixer@latest

Generate the tailwind.config.js file:

npx tailwindcss init

This will create a tailwind.config.js file at the root of your project, configure the purge option:

module.exports = {
   purge: [],
   purge: [
     './resources/**/*.blade.php',
     './resources/**/*.js',
     './resources/**/*.vue',
   ],
    darkMode: false, // or 'media' or 'class'
    theme: {
      extend: {},
    },
    variants: {
      extend: {},
    },
    plugins: [],
  }

In your webpack.mix.js, add tailwindcss as a PostCSS plugin:

  mix.js("resources/js/app.js", "public/js")
    .postCss("resources/css/app.css", "public/css", [
     require("tailwindcss"),
    ]);

Open the ./resources/css/app.css and the @tailwind directive to include Tailwind’s base, components, and utilities styles, replacing the original file contents:

@tailwind base;
@tailwind components;
@tailwind utilities;

Finalizing The Installation

npm install
npm run dev

Configure Database

go to you .env file & update the database variables

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE= #you_database_name
DB_USERNAME= #your_username
DB_PASSWORD= #your_password

Setup The Product Model

Create a new model using the Artisan CLI's command, -mf flag to create a migration and a factory for the product model

php artisan make:model Product -mf

Update The Migration Class

Go to the file database/migrations/xxxx_xx_xx_xxxxxx_create_products_table.php and update the table columns

/**
 * Run the migrations.
 *
 * @return void
 */
public function up()
{
    Schema::create('products', function (Blueprint $table) {
        $table->id();
        $table->string('name');
        $table->double('price', 8, 2);
        $table->boolean('active');
        $table->timestamps();
    });
}

Update The Models

Go to the file app/Models/Product.php and update the product model class

<?php

namespace App\Models;

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

class Product extends Model
{
    use HasFactory;
    protected $fillable = ['name', 'price', 'active'];
}

Update The Product Factory Class

Go to the file database/factories/ProductFactory.php and update the factory class

<?php

namespace Database\Factories;

use Illuminate\Database\Eloquent\Factories\Factory;

class ProductFactory extends Factory
{
    /**
     * Define the model's default state.
     *
     * @return array
     */
    public function definition()
    {
        return [
            'name' => $this->faker->word(),
            'price' => $this->faker->randomNumber(2),
            'active' => $this->faker->boolean()
        ];
    }
}

Create New Records With Tinker

Before start creating the records, you should migrate the product table using Artisan CLI's command

php artisan migrate

• Run the tinker Artisan command
• Create the product records

php artisan tinker 
App\Models\Product::factory()->count(50)->create();

Create PowerGrid Product Table View

To create a PowerGrid table, run the following command:

 > php artisan powergrid:create

 What is the name of your new ⚡ PowerGrid Table (E.g., UserTable)?:
 > ProductTable

 Create Datasource with [M]odel or [C]ollection? (Default: Model):
 > M

 Enter your Model path (E.g., App\Models\User):
 > App\Models\Product

 Create columns based on Model's fillable property? (yes/no) [no]:
 > yes

⚡ ProductTable.php was successfully created at [App/Http/Livewire/].
⚡ Your PowerGrid can be now included with the tag: <livewire:product-table/>

Now open the file resources/views/welcome.blade.php and update it:

<!DOCTYPE html>
<html lang="{{ str_replace('_', '-', app()->getLocale()) }}">

<head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Laravel 8 - Livewire PowerGrid Datatable</title>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <link href="{{ asset('css/app.css') }}" rel="stylesheet">
    {{-- styles --}}
    @livewireStyles
    @powerGridStyles
</head>

<body>
    <div class="min-h-screen bg-gray-100">
        <div class="py-12">
            <div class="max-w-7xl mx-auto sm:px-6 lg:px-8">
                <div class="bg-white overflow-hidden shadow-xl sm:rounded-lg p-5">

                    {{-- Product PowerGrid Tag --}}
                    <livewire:product-table />

                </div>
            </div>
        </div>
    </div>
    {{-- scripts --}}
    @livewireScripts
    @powerGridScripts
</body>

</html>

Testing your application

Generally speaking, tests are a "control check" to guarantee that your application does what it is intended to do. Tests give you confidence that everything is working as it should.

Running tests is also very helpful when we must refactor our code or upgrade a framework version.

To get started, you need to install Pest PHP with the Laravel and the Livewire Plugin.

Run each of the 4 commands below:

composer require pestphp/pest --dev --with-all-dependencies

composer require pestphp/pest-plugin-laravel --dev

php artisan pest:install

composer require pestphp/pest-plugin-livewire --dev

At this point, you are ready to create your test.

Run the command below:

php artisan make:test ProductTableTest --pest

You should now have a new file named: tests/Feature/ProductTableTest.php.

Open the file and replace its content with:

<?php
use App\Models\Product;
use function Pest\Livewire\livewire;

test('Database has products', function () {
    $products = Product::all();

    expect($products->count())->toBeGreaterThan(0);
});

test('Product table renders successfully', function () {
    $this->get('/')
        ->assertOK()
        ->assertSeeLivewire('product-table');
});

The first test is verifying that the database has products.

The second test verifies (assert) that your home page can be rendered without errors (assertOK) and that it contains the Livewire components product-table.

Now, you can run your tests with the command and verify if both tests will ✅ Pass:

php artisan test

Serve your project

First run the the command bellow for compiling new assets

npm run dev

We are ready to run our application

php artisan serve

Now you can open the URL bellow on your browser ``` localhost:8000

Summary

Congratulations 🎉 ! You have create quick datatable using Laravel 8. You did it without having to write a single line of code and that is with the help of PowerGrid Datatable.
