Profiles and Media

Goal

This snapshot advances Driftwood Daily by teaching you to show author profiles and accept constrained avatar uploads.

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

Prerequisites

Use Node.js 20+, npm, and the Wrangler CLI. You should recognize async functions and HTTP verbs.

Port 8787 must be free. Copy .env.example before starting database stages.

• Node.js and npm
• A code editor and terminal
• Wrangler from part 4 onward

Concepts

Upload endpoints must check type and size and store safe data in D1.

Keep handlers thin: routes accept input, D1 queries enforce rules, and Hono JSX escapes output by default.

Walkthrough

Protect profile editing and serve avatars from a dedicated route.

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

if (!['image/jpeg','image/png','image/webp'].includes(type)) return c.text('Bad type', 400);

Run and verify

Enter 08-Profiles-And-Media, install dependencies, copy .env.example when present, and start Wrangler on port 8787.

Open http://127.0.0.1:8787. Watch the terminal for validation and database errors.

git clone https://github.com/michaeldunga1/fcc-hono-blog.git
cd fcc-hono-blog/08-Profiles-And-Media
npm install
cp .env.example .env
npm run dev

Troubleshooting

Confirm multipart enctype and field name.

For D1 failures, confirm Wrangler is running and the driftwood_NN binding matches this folder. Never commit .env or .wrangler secrets.

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

Try this

Upload a valid image, then reject a text file.

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
