Registration

Goal

This snapshot advances Stellar Press by teaching you to validate accounts and store bcrypt hashes.

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 for SQLite stages.

Port 4321 must be free. Copy .env.example before starting database stages.

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

Concepts

Registration normalizes email, checks uniqueness, and stores a one-way hash.

Keep server endpoints thin: pages present data, API routes enforce rules, and Astro escapes output by default.

Walkthrough

Accept a form POST, validate password length, hash, and save.

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

const hash = await bcrypt.hash(password, 10)
db.prepare('INSERT INTO users ...').run(...)

Run and verify

Enter 06-Registration, install dependencies, copy .env.example, and start Astro on port 4321.

Open http://127.0.0.1:4321. Watch the terminal for validation and database errors.

git clone https://github.com/michaeldunga1/fcc-astro-blog.git
cd fcc-astro-blog/06-Registration
npm install
cp .env.example .env
npm run dev -- --port 4321

Troubleshooting

Duplicate email should return a clear form error.

For database failures, confirm Docker/Wrangler and the *.db name when applicable. Never commit .env, *.db, or node_modules.

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

Try this

Try a short password and a duplicate email.

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
