Profiles and Media

Goal

This snapshot advances Glasspoint Notes by teaching you to show 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 a terminal. No Docker is required — each snapshot uses a local SQLite file.

Port 3006 must be free. Copy .env.example before starting database stages.

• Node.js and npm
• A code editor and terminal

Concepts

Upload endpoints must check type and size and store safe filenames.

Keep handlers thin: Express routes load data, Lit templates present escaped HTML, and mutations re-check authorization on the server.

Walkthrough

Protect profile editing and serve uploads.

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

if (!ALLOWED.includes(file.mimetype)) return res.status(400).send('Unsupported image type')

Run and verify

Enter 08-Profiles-And-Media, install dependencies, copy .env.example, and start Express on port 3006.

Open http://127.0.0.1:3006. Watch the terminal for validation and database errors.

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

Troubleshooting

Confirm multipart enctype and field name.

For database failures, delete glasspoint.db and restart so schema and seeds recreate. Never commit .env, *.db, or node_modules.

• 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
