Profiles and Media

Show author profiles and accept constrained avatar uploads.

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
