As an asynchronous event driven JavaScript runtime, Node is designed to build scalable network applications. In the following 'hello world' example, many connections can be handled concurrently. Upon each connection the callback is fired, but if there is no work to be done, Node 64 bit will sleep.
This is in contrast to today's more common concurrency model where OS threads are employed. Thread-based networking is relatively inefficient and very difficult to use. Furthermore, users of Nodejs are free from worries of dead-locking the process, since there are no locks. Almost no function in the app directly performs I/O, so the process never blocks. Because nothing blocks, scalable systems are very reasonable to develop in Node.
Node.js is similar in design to, and influenced by, systems like Ruby's Event Machine or Python's Twisted. It takes the event model a bit further. It presents an event loop as a runtime construct instead of as a library. In other systems there is always a blocking call to start the event-loop. Typically behavior is defined through callbacks at the beginning of a script and at the end starts a server through a blocking call like EventMachine::run(). In Node js there is no such start-the-event-loop call. It simply enters the event loop after executing the input script. The tool exits the event loop when there are no more callbacks to perform. This behavior is like browser JavaScript — the event loop is hidden from the user.
HTTP is a first class citizen in Nodejs, designed with streaming and low latency in mind. This makes Node js well suited for the foundation of a web library or framework.
Just because Nodejs is designed without threads, doesn't mean you cannot take advantage of multiple cores in your environment. Child processes can be spawned by using child_process.fork() API, and are designed to be easy to communicate with. Built upon that same interface is the cluster module, which allows you to share sockets between processes to enable load balancing over your cores.

- Install Node.js binary distribution
Jul 25, 2019 Node.js is a free and open source server-side JavaScript environment that uses an asynchronous event-driven model. Moreover, Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Installing Node.js® and NPM on Mac. Homebrew has to download some files and install them. But that’s it. Make sure you have Node and NPM installed by running simple commands to see what version of each is installed: Test Node. To see if Node is installed, type node -v in Terminal. There are several ways to install Node.js and NPM on the Mac, including using a prebuilt packaged installer, or by using Homebrew. This tutorial will cover both, and either approach should work find on any modern version of MacOS system software.

Node.js installation is a simple task. We just need the right steps. In this tutorial, we shall learn to setup environment for Node.js and the prerequisites to start developing Node.js applications.
JavaScript programming language is used for Node.js Application Development. The source files of Node.js applications have extension of “.js”. Any text editor is sufficient to write Node.js code and save it as .js file. To interpret the instructions written in the source .js files, Node.js interpreter is required. The Node.js is available as a binary distribution.

Install Node.js binary distribution
Download the latest binary distribution from https://nodejs.org/download/release/latest/. Based on the Operating System and Architecture, download a suitable package. The size would be less than 20MB.
Following are the latest packages available at the time of writing this tutorials (for x64) :
OS | Package |
Linux | node-v8.4.0-linux-x64.tar.gz |
MacOS | node-v8.4.0-darwin-x64.tar.gz |
Windows | node-v8.4.0-win-x64.zip |
SunOS | node-v8.4.0-sunos-x64.tar.gz |
For linux kernel based OS like Ubuntu/MacOS/SunOS

Once the download is complete, extract the package and include it in the system path variable.
Go to the downloaded folder, Open a Terminal from there and execute the following commands.
Unzip the compressed package
Make nodejs directory in
/usr/local/
. Replace the file name, if it is different from what you have downloaded.Move the extracted nodejs package to
/usr/local/nodejs/
. Provide user password if asked.~$ sudo mv node-v8.4.0-linux-x64/*/usr/local/nodejs/ |
Add the path
/usr/local/nodejs/bin
to PATH environment variable. Provide user password if asked.Node 8 Download
Open
.bashrc
file and append the nodejs’ path at the end. To edit .bashrc, open a terminal and run the following command :Add the following line at the end of
.bashrc
file. $ export PATH=$PATH:/usr/local/nodejs/bin |
Once after adding the line, close the terminal and reopen again.

To verify if nodejs path has been added to PATH environment variable, run the following command :
For Windows OS, the value echoed back should have
/usr/local/nodejs/bin
.For installing Node.js on Windows Operating System, double click on the .msi file and follow the prompt step by step. Finishing the prompt should install Node.js with PATH added to the environment variables.
Verify Node.js installation
Using a Text Editor, create a sample file with name
verifyNode.js
and copy paste the following content to that file.And run the following command in Command prompt or Terminal from the directory of
verifyNode.js
script file.Run Node.js File
Following is the syntax to run a Node.js file using node command line interface :
