Node.js Architecture Explained

Node.js has changed backend development by allowing developers to build scalable applications using JavaScript.

How Node.js Works

Node.js runs JavaScript using the V8 engine and handles operations through an event-driven architecture.

Event Driven Model

Instead of creating separate threads for every request, Node.js uses asynchronous operations to handle many connections efficiently.

Main Components

Node.js applications include:

• Event Loop
• Call Stack
• APIs
• Callback Queue

Benefits

Node.js is commonly used for APIs, real-time applications, and microservices.

Final Thoughts

Understanding Node.js architecture helps developers create faster and more scalable backend systems.
