Posts CRUD and Ownership

Goal

This snapshot advances Glasspoint Notes 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 — each snapshot uses a local SQLite file.

Port 3006 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.author_id.

Keep handlers thin: Express routes load data, Lit templates present escaped HTML, and mutations re-check authorization on the server.

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 (user.id !== post.author_id) return res.status(403).send('Forbidden')

Run and verify

Enter 09-Posts-CRUD-And-Ownership, install dependencies, copy .env.example, and start Express on port 3006.

Open http://127.0.0.1:3006. Watch the terminal for validation and database errors.

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

Troubleshooting

UI hiding is not authorization.

For database failures, delete glasspoint.db and restart so schema and seeds recreate. 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
