![]() ![]() ![]() The server starts processing it and when there is a blocking IO operation, it does not wait until it completes and instead registers a callback function. Basically the server consists of one thread processing one event after another.Ī new request coming in is one kind of event. No Buffering – Node.js applications never buffer any data. There is an Active and vibrant community for the Node.js framework – The active community always keeps the framework updated with the latest trends in the web development. Hence, development in Node.js becomes easier for a developer who knows JavaScript. The majority of developers are already well-versed in JavaScript. Node.js library uses JavaScript – This is another important aspect of Node.js from the developer's point of view. Traditional servers create limited threads to handle requests while Node.js creates a single thread that provides service to much larger numbers of such requests. However, this does not block other operations. The response from these events may or may not reach the server immediately. ![]() Single Threaded but Highly Scalable – Node.js uses a single thread model for event looping. Node has a wrapper over the JavaScript engine which makes the runtime engine much faster and hence processing of requests within Node.js also become faster. Thus it will not wait for the response from the previous requests.įast in Code execution – Node.js uses the V8 JavaScript Runtime engine, the one which is used by Google Chrome. This feature means that if a Node receives a request for some Input/Output operation, it will execute that operation in the background and continue with the processing of other requests. What are the key features of Node.js?Īsynchronous and Event driven – All APIs of Node.js are asynchronous. ![]()
