Node.js is a lean, fast server-side belvedere which is congenital on Google Chrome’s JavaScript Engine. It was accounting by Ryan Dahl in 2009 and its latest adaptation accessible is v0.10.36. The acceptation as supplied by its official affidavit is as follows.

It is a belvedere congenital on Chrome’s JavaScript runtime with a motive of simple architecture of fast and scalable arrangement applications. It adopts an event-driven, non-blocking I/O archetypal which makes it failing and efficient, and aswell absolute for data-intensive real-time applications run beyond altered broadcast devices.

It is declared as a JavaScript runtime ambiance which is both cross-platform and accessible – source. It advantageous for both servers and desktop applications.The applications are accounting application JavaScript, and they can run aural the Node.js runtime on the afterward OS X, Microsoft Windows, and Linux.

It aswell presents a well-equipped library of assorted JavaScript modules that abridge the development of web applications application the belvedere to a abundant extent.

Features of Node.js are as follows:

Non Blocking and focus is on the Event − All API’s of Node.js library are asynchronous, i.e. they are non-blocking. It originally agency a Node.js based server will never delay for an API to acknowledgment the data. The server again moves over to the next API afterwards calling it. It again application notification apparatus of Events of this belvedere helps the server to get a acknowledgment from the antecedent API call.

Very Fast - Since this belvedere is bogus on Google Chrome’s V8 JavaScript Engine, its library is actual fast in cipher execution.

Even admitting it is Individual Threaded yet it is Awful Scalable − This belvedere utilizes a individual threaded archetypal forth with accident looping. Accident apparatus aids the server to alternate in a non-blocking way and aswell makes the server awful scalable afraid to the acceptable servers which acclimated to actualize apprenticed accoutrement to handle the requests. It utilizes a affairs which is individual threaded and can align account to a abundant bigger amount of requests in allegory to the acceptable servers like Apache HTTP Server.

No Buffering - The applications of this belvedere never buffers any data. These applications artlessly accommodate achievement to the abstracts in chunks.

License – The authorization for Node.js was appear beneath the MIT license.

This belvedere is acclimated by the afterward Companies in its operations follows: eBay, General Electric, GoDaddy, Microsoft, PayPal, Uber, Wikipins, Yahoo!, and Yammer to name a few.

Following are the breadth in which Node.js is proves itself as an ideal abstruse partner.

• Adopts I/O apprenticed Applications

• Abstracts Streaming Applications

• Abstracts Intensive Real-time Applications (DIRT)

• JSON APIs based Applications

• Individual Page Applications
