Alternatives

Some examples of alternatives to Node.js that we suggest are Ruby on Rails, Django, Laravel and Cake PHP. To see a complete list of alternatives, check out our website. Vertex , not a java script vm, but runs java script (and many others) on JVM, great alternative to nodejs … backed by Red hat.

 

Advantages

In general, any CPU intensive operation annuls all the throughput benefits Node offers with its event-driven, non-blocking I/O model because any incoming requests will be blocked while the thread is occupied with your number-crunching. As stated previously, Node.js is single-threaded and uses only a single CPU core.

 

Applications

  •         Speed (runs on Google JS engine)
  •         Non-blocking I/O paradigm.
  •         Data streaming (HTTP requests and responses as a single event)
  •         Real-time apps (client-side and server-side)

Certification

The advantage of the Node.js Certified Developer (NCD) program is to provide assurance that NCDs have the skills, knowledge, and competency to perform the responsibilities of an intermediate Node.js developer. The certification exam conducted through an online exam which requires good knowledge in Node js.

 

Definition

Node.js (Node) is an open source development platform for executing Java Script code server-side. … Node.js is intended to run on a dedicated HTTP server and to employ a single thread with one process at a time. Node.js applications are event-based and run asynchronously.

 

What is the definition of a node?

A node is a basic unit used in computer science. Nodes are devices or data points on a larger network. Devices such as a personal computer, cell phone, or printer are nodes. When defining nodes on the internet, a node is anything that has an IP address.

 

What is the node JS?

Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. Node.js is an open source, cross-platform runtime environment for developing server-side and networking applications.

 

Features

Asynchronous and Event Driven − All APIs of Node.js library are asynchronous, that is, non-blocking.

Very Fast − Being built on Google Chrome’s V8 JavaScript Engine, Node.js library is very fast in code execution.

 

History

Node.js was originally written by Ryan Dahl in 2009, about thirteen years after the introduction of the first server-side JavaScript environment, Netscape’s Live Wire Pro Web. The initial release supported only Linux and Mac OS X. Its development and maintenance was led by Dahl and later sponsored by Joyent.

 

Limitations

There are following limitations of Node.js: It doesn’t support multi-threaded programming. It doesn’t support very high computational intensive tasks. When it executes long running task, it will queue all the incoming requests to wait for execution, since it follows JavaScript event loop which is single threaded.

 

What is good about node js?

Not All Uses Are Good Uses for Node.js. Node.js is a server-side JavaScript environment. It uses an asynchronous event-driven model and is designed for writing scalable internet applications, notably web servers

 

Overview

Overview. Node.js is a runtime environment for JavaScript that runs on the server. Node.js is open source, cross platform, and since its introduction in 2009 it got hugely popular and now plays a significant role in the web development scene.

 

Purpose

Node.js is a platform built on Chrome’s JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven ,non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

 

Security

The Node.js Security project to bring vulnerability data into the Foundation, review and recommend processes for handling of security reports, recommend security improvements for the core Node.js project, facilitate and promote the expansion of a healthy security service and product provider ecosystem vulnerabilities.
