Node Architecture

This lesson is part of Node.js · All levels

Summary

The architecture uses a single-threaded event loop pattern to handle many connections at once without creating new threads per request. While blocking operations like file reading or DNS lookup are delegated to the thread pool in libuv. This model makes Node efficient for I/O-based applications. (Node.js)

Key points

One main thread runs an event loop that handles many requests
Libuv provides event loops and thread pools for blocking calls
The event emitter pattern separates producer and consumer event
Modular structure based on CommonJS or ES Modules
