![]() Node.js is a good solution to perform data-intensive tasks or real-time analytics since it has asynchronous architecture and non-blocking I/O features. Therefore, the event loop will only move to the next one if the previous task is finished. In comparison, synchronous architecture software performs one task at a time. ![]() Since Node.js uses a single-threaded event loop, it can deal with multiple requests simultaneously with faster execution times, and less resource usage. The event loop will finish all prior and current requests before executing a callback function to send the server’s response to the client. Once it has received a response from the previous API call, it puts the reply in the event queue. On the asynchronous architecture, the event loop operates in an event-driven manner. Asynchronous ArchitectureĪs previously discussed, the Node.js thread doesn’t wait for a response and moves on to process a subsequent request. That said, Node.js is not suitable for CPU-intensive tasks as they could prevent the main thread from handling other requests, effectively blocking it. ![]() This way, it can handle a massive amount of concurrent requests. Instead of blocking the thread and wasting CPU resources by waiting for a response, Node.js will continue working on the next task. Node.js employs non-blocking I/O operations – when a client sends a request to the web server, the single-threaded event loop picks it up and sends it to a worker thread for processing. A thread is a set of instructions that need to be performed by the server. It operates as a single process, which means it doesn’t create a new thread for every request. How Does Node.js Work?Ĭompared to other platforms, Node.js has a particular workflow. It is open-source software to build real-time and scalable network applications. ![]() Node.js is a single-threaded, cross-platform runtime environment built on Chrome’s V8 JavaScript engine. ![]()
