How old is node.js

It introduces a lot of innovative thinking and approaches for JavaScript server-side development that have already helped many developers. Believe it or not, Node. In this post, we draw the big picture of Node.

Well, after over 20 years of stateless-web based on the stateless request-response paradigm, we finally have web applications with real-time, two-way connections, where both the client and server can initiate communication, allowing them to exchange data freely.

This is in stark contrast to the typical web response paradigm, where the client always initiates communication. The things that we can do on the web nowadays with JavaScript running on the server, as well as in the browser, were hard to imagine just several years ago, or were encapsulated within sandboxed environments like Flash or Java Applets. Before digging into Node. As this is more a benefit of JavaScript than Node.

In Node. In one sentence: Node. Plus, they were run in isolation and often operated over non-standard ports, which may have required extra permissions and such. With all of its advantages, Node. The Node. In this Node. The main idea of Node. What it really means is that Node. And understanding this is absolutely essential. How it works under-the-hood is pretty interesting. Compared to traditional web-serving techniques where each connection request spawns a new thread, taking up system RAM and eventually maxing-out at the amount of RAM available, Node.

By avoiding all that, Node. There is, of course, the question of sharing a single thread between all clients requests, and it is a potential pitfall of writing Node. Secondly, developers need to be really careful not to allow an exception bubbling up to the core topmost Node.

The technique used to avoid exceptions bubbling up to the surface is passing errors back to the caller as callback parameters instead of throwing them, like in other environments. Even if some unhandled exception manages to bubble up, tools have been developed to monitor the Node. When discussing Node. The idea of NPM modules is quite similar to that of Ruby Gems : a set of publicly available, reusable components, available through easy installation via an online repository, with version and dependency management.

A full list of packaged modules can be found on the npm website , or accessed using the npm CLI tool that automatically gets installed with Node. The module ecosystem is open to all, and anyone can publish their own module that will be listed in the npm repository.

The list goes on. Your computer is now a server. Your computer is accessible on port A few examples of enterprise users of Node.
