Login and Session Cart

Goal

This snapshot advances Quaycart Market by teaching you to authenticate users and keep a session shopping cart.

Every numbered folder is a complete app. Run this stage independently, then compare it with the previous folder.

Prerequisites

Use PHP 8.2+, Composer, Node.js 20+, npm, and Docker for MySQL stages.

Port 8004 must be free. Copy .env.example before database stages.

• PHP and Composer
• Node.js and npm
• Docker from part 4 onward

Concepts

The session guard restores the user; the cart lives in session as product id to quantity until checkout.

Livewire keeps interactive UI on the server with components; Tailwind styles the storefront; Eloquent owns persistence and authorization checks.

Walkthrough

Add login/logout Livewire actions and an Add to Cart component that updates session state.

Read the example, then open the matching snapshot. The repository includes validation, CSRF, and the surrounding structure.

$cart = session()->get('cart', []);
$cart[$productId] = ($cart[$productId] ?? 0) + 1;
session()->put('cart', $cart);

Run and verify

Enter 07-Login-And-Cart, install PHP and Node dependencies, copy .env.example, migrate, seed, build assets, and serve on port 8004.

Open http://127.0.0.1:8004. From data lessons onward, Ada and Grace use password123.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-laravel-ecommerce.git
cd fcc-laravel-ecommerce/07-Login-And-Cart
composer install
npm install
cp .env.example .env
php artisan key:generate
php artisan migrate --seed
php artisan storage:link
npm run build
php artisan serve --host=0.0.0.0 --port=8004

Troubleshooting

A changed APP_KEY invalidates sessions; clear cookies and try again.

For database failures, confirm Docker and the quaycart_NN name. Never commit .env, vendor, or node_modules.

• Read the first exception first
• Rebuild assets after Tailwind class changes
• Never commit secrets

Try this

Log in as Ada, add two items, refresh, and confirm the cart badge persists.

Test a happy path and one invalid or unauthorized request.

• Make one small change
• Test it in the browser
• Compare with the next snapshot only after it works
