Routing

Goal

This snapshot advances Saltmarsh Daily by teaching you to organize page routes.

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

Prerequisites

Use Deno 2+ and a code editor. No Docker is required — each snapshot uses its own SQLite file.

Port 8003 must be free. Copy .env.example before starting database stages.

• Deno runtime
• A code editor and terminal

Concepts

File routes map URLs to handlers and JSX pages.

Keep handlers thin: routes present data, server logic enforces rules, and Fresh escapes JSX output by default.

Walkthrough

Add home, about, and health routes.

Read the example, then open the matching snapshot. The repository includes the surrounding setup and error handling.

export default function About() {
  return <main><h1>About Saltmarsh Daily</h1></main>;
}

Run and verify

Enter 02-Routing, install deps, copy .env.example, and start Fresh on port 8003.

Open http://127.0.0.1:8003. Watch the terminal for validation and database errors.

git clone https://github.com/michaeldunga1/fcc-fresh-blog.git
cd fcc-fresh-blog/02-Routing
deno install
cp .env.example .env
deno task start

Troubleshooting

A missing route file leaves the path as 404.

For SQLite failures, confirm DATABASE_PATH and write permissions. Never commit .env or the .db file.

• Read the first error first
• Restart after environment changes
• Never commit secrets

Try this

Add a /contact plain-text route.

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
