Layout and UI

Goal

This snapshot advances Rivergate 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 .NET 8 SDK and Docker for Postgres stages.

Port 5082 must be free. Copy .env.example before database stages.

• .NET 8 SDK
• A code editor and terminal
• Docker from part 4 onward

Concepts

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

Razor Pages keep handlers close to markup; cookie auth owns the session; EF Core persists catalog and orders.

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.

<partial name="_ProductCard" model="product" />

Run and verify

Enter 03-Layout-And-UI, copy .env.example, restore, migrate, and dotnet run on port 5082.

Open http://127.0.0.1:5082. From data lessons onward, Ada and Grace use password123.

git clone https://github.com/michaeldunga1/fcc-aspnet-ecommerce.git
cd fcc-aspnet-ecommerce/03-Layout-And-UI
cp .env.example .env
dotnet restore
dotnet ef database update
dotnet run --urls http://0.0.0.0:5082

Troubleshooting

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

For database failures, confirm Docker and the river_NN name. Never commit .env, bin/, obj/, or secrets.

• 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
