Posts CRUD and Ownership

Create, edit, and delete posts with owner authorization.

Goal

This snapshot advances Beaconrock Digest by teaching you to create, edit, and delete posts with owner authorization.

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 3005 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

Authorization compares session user id with post.authorId.

Keep the server boundary visible: routeLoader$ reads trusted data; routeAction$ validates input and re-checks authorization before mutations.

Walkthrough

Return 403 when another account mutates.

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

if (userId !== post.authorId) {
  fail(403, { message: 'Forbidden' })
}

Run and verify

Enter 09-Posts-CRUD-And-Ownership, install dependencies, copy .env.example, and start Qwik City on port 3005.

Open http://127.0.0.1:3005. Watch the terminal for validation and database errors.

docker compose up -d
git clone https://github.com/michaeldunga1/fcc-qwik-blog.git
cd fcc-qwik-blog/09-Posts-CRUD-And-Ownership
npm install
cp .env.example .env
npm run dev

Troubleshooting

UI hiding is not authorization.

For database failures, confirm Docker is running and the beaconrock_NN name matches the snapshot. Never commit .env or node_modules.

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

Try this

Log in as Ada and confirm Grace's post returns 403 on delete.

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
