Routing

Goal

This snapshot advances Rivergate Market by teaching you to register shop routes for catalog, cart, and health.

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

Named routes keep template links stable when URLs change.

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

Walkthrough

Add home, about, health, and placeholder catalog routes.

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

@page "/"
public class IndexModel : PageModel { }

Run and verify

Enter 02-Routing, 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/02-Routing
cp .env.example .env
dotnet restore
dotnet ef database update
dotnet run --urls http://0.0.0.0:5082

Troubleshooting

A 404 usually means the verb or URI does not match the router table.

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 a named /contact route and link it from the layout.

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
