I tried writing my first NodeJS program on Ubuntu. Since I am learning Ubuntu and Linux in my free time. You can start writing your first Hello World program in Node JS as shown in the video below: Ubuntu based Linux Distribution: After Installation NodeJS can be installed by using the installers which can be downloaded from the below page:Īlternatively you can install NodeJS from package manager as mentioned in the below articles. Lets get started and get our hands dirty with some non stop fun. That’s enough of the introduction about the NodeJS. Node’s event loop and “non blocking” IO don’t allow Node to do multiple things at one time, it just allows node to schedule things later. Node JS is single threaded application.There can be synchronous and asynchronous tasks added to the node js file, The event loop takes care of the asynchronous tasks and keeps checking if there are more tasks to be completed,.Each part or tick consists of the Node JS continuously checking if there is anything else to process. The event loop is an infinitily completing task which starts as soon as it completes.In fact it first initializes the process called event loop and then it initializes the initial parts of your JS file and then it processes the event loop. The above command does not simply sends the script file to V8 engine.Script processor is simply called by the name of the script file and executed by node.Node JS now presents itself as two applications: a script processor and a REPL (Read Eval Print Loop).Node js is C++ application that embeds the V8.Node JS packages the javascript file and sends them to V8 engine.Node JS is server side JS runtime environment built on chrome’s V8 JavaScript Engine.Parsing the Query String, HTTP Method, request Path and payload for NodeJS.Simple Trick to create a NodeJS Server on Windows/Ubuntu.Writing my first Hello World program in Node JS.This is the First article in the series for NodeJS free article on this blog: But slowly and steadily the language made its inroads in the technology and internet world.Īnd today it is one of the most used server side language along with MEAN stack. Ryan Dahl first proposed the language in 2009 but there were not many takers of this server side JavaScript programming language. Lets have a look at the history of this programming language. But before going further and writing first Hello World program in NodeJS. I this article I will help you to understand you first hello world program in Node JS. And I would say that Node.JS is not quite new. Hello Friends, We are hearing a lot about the JavaScript programming on the server side with the help of Node.JS.
