Profiles and Media

Goal

This snapshot advances Harborline Digest 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 Docker for Postgres stages.

Port 3003 must be free. Copy .env.example before starting database stages.

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

Concepts

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

Keep server routes thin: pages present data, server handlers enforce rules, and templates escape output by default.

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 (!['image/jpeg','image/png','image/webp'].includes(type)) throw createError({ statusCode: 400 })

Run and verify

Enter 08-Profiles-And-Media, install dependencies, copy .env.example, and start Nuxt on port 3003.

Open http://127.0.0.1:3003. Watch the terminal for validation and database errors.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-nuxt-blog.git
cd fcc-nuxt-blog/08-Profiles-And-Media
npm install
cp .env.example .env
npm run dev -- --port 3003

Troubleshooting

Confirm multipart enctype and field name.

For database failures, confirm Docker/Wrangler and the harborline_NN name when applicable. Never commit .env 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
