Welcome to the real-time web!
For a Technologies’ Company, enhancing its knowledge base is of key importance. Synsoft Global continuously strives to expand its realm of knowledge through expert training sessions, hand-on, as well as deep-diving self-study and practice.
Why the growing popularity in Node.js?
Node.js gives developers the opportunity to work in non-blocking, event-driven environment. With Node.js, real-time web applications can use a 2-way communication paradigm and can push data to the client. This is indeed revolutionary! After being limited be the stateless-web, and being used to working on the stateless request-response model, we can finally have web applications where both the client and server can “initiate” communication, in contrast to the client initiated communication characteristic of the typical web response.
The Substance of Node.js
Node.js is Single-Threaded and uses only a single CPU core, but does asynchronous I/O. Having asynchronous I/O is good, as I/O is most expensive and why should we be waiting for I/O operations to complete when CPU is free. So if we make a database call in our code, Node will spawn it asynchronously, and continue to process other requests while the database operation takes its time. In this way, Node gives us the simplicity of synchronous code, while we still benefit from parallel processing, even without having to worry about it. Just by using callbacks while doing I/O guarantees that our code is never interrupted. And without having to experience the costs and complexity of multithreading in a request, we are ensured that our I/O will not block other requests.
So, while it very efficiently solves the I/O scaling problem, it is not the best choice for applications demanding heavy computations, or having blocking operations.
This extensive training session on Node.js and its Programming techniques gave Synsoft’s team an opportunity to enrich themselves by validating their Node.js skills in developing high performance web and mobile applications.
Synsoft’s team completed this 3 day training session and emerged keen and well-equipped, ready to put to use their knowledge in building fast and scalable network applications using Node.js and MongoDB.
