Overview

While Node has a native http module, most developers use frameworks like Express.js for easier routing and middleware.

Code Example

// Optional Node.js ecosystem example — Express.js\nimport express from "express";\nconst app = express();\napp.get("/", (req, res) => res.json({ ok: true }));

Web Development Context

In modern web development, understanding Web Frameworks (Express) is crucial. Node.js is widely used for building APIs, real-time applications, and microservices. Mastery of this concept allows you to build efficient, scalable, and secure backend systems.

Common Mistakes

• Blocking the event loop with heavy synchronous tasks.
• Exposing secrets in code instead of environment variables.
• Forgetting to handle promise rejections.
