Master Node.js Core: Event Loop, Streams, Clusters & More
This article reviews the essential Node.js core concepts—including the event loop, global and process objects, event emitters, streams and buffers, clustering, asynchronous error handling, and creating C++ addons—to help developers solidify their understanding and fill knowledge gaps.
Having used Node.js for a long time, how well do you actually understand its core functionalities?
Event Loop: the key to non‑blocking I/O
Global and process: accessing more runtime information
Event emitters: the event model
Streams and buffers: efficient data handling
Clusters: multi‑process model
Handling async errors: asynchronous error handling
C++ addons: how to use your own C++ modules
Seeing all these terms can be overwhelming, but don’t worry—read on to explore each concept in depth, and even seasoned developers can review to fill any gaps.
