Posts CRUD and Ownership

Goal

This snapshot advances Stellar Press 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 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

Authorization compares session user id with post.authorId.

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

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.author_id) return new Response('Forbidden', { status: 403 })

Run and verify

Enter 09-Posts-CRUD-And-Ownership, 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/09-Posts-CRUD-And-Ownership
npm install
cp .env.example .env
npm run dev -- --port 4321

Troubleshooting

UI hiding is not authorization.

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

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
