Registration

Goal

This snapshot advances Emberquay Journal 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 Docker for Postgres stages.

Port 3007 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

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

Keep server functions thin: loaders read, actions mutate, and Solid components present escaped values.

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 hash(password)
await db.insert(users).values({ email, passwordHash: hash })

Run and verify

Enter 06-Registration, install dependencies, copy .env.example, and start SolidStart on port 3007.

Open http://127.0.0.1:3007. Watch the terminal for validation and database errors.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-solid-blog.git
cd fcc-solid-blog/06-Registration
npm install
cp .env.example .env
npm run dev -- --port 3007

Troubleshooting

Duplicate email should return a clear form error.

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