Layout and UI

Goal

This snapshot advances Stonequay Market by teaching you to build a shared Tailwind layout and product card shell.

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+, and Docker for MySQL stages.

Port 8005 must be free. Copy .env.example before database stages.

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

Concepts

One layout owns navigation, flash banners, and the cart badge.

Twig escapes output by default; Tailwind styles the storefront; Doctrine owns persistence and voters enforce ownership.

Walkthrough

Compose the storefront chrome with sample product cards before persistence exists.

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

{% extends 'base.html.twig' %}
{% block body %}{% include 'product/_card.html.twig' %}{% endblock %}

Run and verify

Enter 03-Layout-And-UI, composer install, copy .env, migrate, seed, build assets, and serve on port 8005.

Open http://127.0.0.1:8005. From data lessons onward, Ada and Grace use password123.

git clone https://github.com/michaeldunga1/fcc-symfony-ecommerce.git
cd fcc-symfony-ecommerce/03-Layout-And-UI
composer install
npm install
cp .env.example .env
php bin/console doctrine:migrations:migrate -n
php bin/console app:seed
npm run build
symfony server:start --port=8005 --no-tls
# or: php -S 0.0.0.0:8005 -t public

Troubleshooting

Missing Tailwind classes after edits usually mean assets were not rebuilt.

For database failures, confirm Docker and the stone_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

Add an empty-state message when the sample product list is empty.

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
