Introduction to Node.js Developers
To know what a Node.Js developer is and what it is for, we believe that you first have to talk about the definition of what Node.Js is.
With these elements, we can now enter the developer’s territory. Node.js shines in real-time web applications using push technology through Websockets.
Examples where Node.js should be needed:
It is the most typical real-time and multi-user application. From IRC (on the day), through many owners and open protocols spinning on non-standard ports, with the ability to instrument everything in Node.js with websockets running over standard port 80.
The chat app is really perfect for Node.js: it is light, it has high data intensive traffic (but low/compute processing) and it is an app that works on distributed devices. It is also a great use case for learning as it is too simple but at the same time it covers most of the tools you can use in a typical Node.js application.
On more traditional web platforms, HTTP requests and responses are treated as isolated events; in fact, they are really ordinary. This observation can be used in Node.js to build some cool features. For example, it is possible to process files while they are being uploaded, since the data enters through a stream, and can be processed in a fashionable line. This could be done in real time for audio or video encoding, as a proxy between different data sources (see next section).
Node PROXY.js is used as a proxy server which can handle a large number of simultaneous connections in a non-blocking mode. It is especially useful for proxying different services with different response times, or for collecting data from multiple points of origin.
Doing a great job description for a Node.js developer needs to be mindful of concerns. When you’re looking for an advanced Node.js developer, posting a generic description of the web developer in your job posting will bring in many people who may well be skilled in creating user interfaces, some web designers, but all with little knowledge about programming.
