Lesson 3: Backend Logic with Node.js and AI Automation

Backends require strict security and clean data handling. We use [Node.js] with [Express] to create lightweight servers. AI excels at generating database models for [Prisma] or Mongoose. Example Code: app.post('/api/data', (req, res) => { /* AI-generated logic here */ }); This setup allows you to focus on system architecture rather than repetitive CRUD code. Refer to the Node.js Official Documentation for security best practices. [API] testing is critical here. ### FAQs 1. Is Node.js still relevant? Yes, it powers 70% of modern stacks. 2. Can AI debug errors? Yes, paste the stack trace into your chat window. 3. What database should I use? PostgreSQL is recommended for 2026 standards.
