Node JS Installation

[Music] welcome back aliens my name is Devin Reggie and in this video we'll see how to install node.js and Visual Studio code on windows machine now see you can do this code on different OS you if you are using Linux or Mac or Windows it works on all the systems so no J's and vias code works on all different platforms and first of all for the if you want to continue with the CDs if you want to see how the basics of node.js you can use any IDE which you prefer I will be using visual vs code which works perfectly for nodejs so you can use that and it also has some extensions you can use now first need to verify in your system do you have no jails see the thing is when you install when you work on some projects or when you have when you install some software there might be a chance that those projects or the software's need nodejs as a dependency so maybe in your machine you might be having node.js by default so how do you verify so you can just go to CMD Oil comment or maybe terminal or command prompt and here you can simply search for node V which is version so if it is giving you the version that means no DS installed so you can continue with that otherwise it will show node is not recognized that's perfect right so in this machine I don't have notice now the thing is even if you have not installed in your machine it might be a old version and we want to work on the new version so at least the second-last was and not the latest so let's install node or let's upgrade note if you have so the best option is if you already have not in your machine just remove it so that you can you can do a fresh installation so what we will do is to install node let's go to the official website of node.js so let's go to browser and search for node.js and this and it will give you a list of websites and of course we need to go to the official one which is node.js dot o-r-g and if you can go there before installation I just want to show you the website it tells you a lot of things the first thing it says is no J's is a JavaScript runtime ok so which we have talked about this in the earlier video built on Chrome's create Joseph's engine so it is built on v8 as we have discussed and and if you go to the about a section of node.js you can see it gives you a sample example it explains the concept it supports why it is even true and why it is a synchronous and you can have a look on look look at those things but we want to go to the back to the home and you can see we have an option of download for Windows now depend upon what OS you have if you are using linux mac and windows it works on all the different OS and if you can just click on the Downloads tab it will give you different options there are two things actually here with one is LTS and second is current LTS is long-term support whenever you go go with the latest version that means it will having a longer support we want to go for the current one and while you are learning you can choose any one right you can choose a latinas or you can use into c-can't one but yes when you when you are going for a production software when you are building the the DL projects then you have to think about these versions now when you click on current of course depend upon which also you have you can choose I'm using Windows and 64-bit so I'll be using 64-bit MSI so you can just click on this and it will download the node.js for you so as you can see I have the node.js set up in my machine and we just have to install this now do you install it it's very simple right you just have took the level click it and it will give you some options we have to say next you don't know about and we don't have a choice we have to accept the agreement say next and this is a path you have to mention of course the default works say next nothing much here it says add to the path yes it will be adding to the path let's do that ok now this is important this is important tab so so it says automatically install the necessary tools and note that this will also install chocolaty chocolaty is npm for for windows and we have talked about npm before right so it's a very handy tool so it's like i would recommend you to take this and say installation it might take more time so when you say take and it will not download a lot of different tools for no chairs and if you are serious about this make sure that you have all those tools available with you say next and click on install yes let me take some time for the installation now as you can see this setup is complete you just have to click on finish now since I'm doing this for the second time it has not given me extra prompts which I got in the first installation so you might get those prompt about installing the chocolaty and it will take more space so you just have to say yes and click on install now once you click on finish you can see oh it is still continuing but that's the prompt I was talking about okay so it is downloading the extra tools so first it will get the latest version of chocolaty and by the time it gets the installation let's head towards the website of chocolaty so let's go to the website of chocolaty now a chocolaty this is a website so it's a package manager for Windows so we can use this tool for the extra modules you want okay so everything is done it has installed this software click on enter and I guess we have the setup ready now but how do you verify this and for this you have to go to go back to a command prompt and say node V and oh it is still not installed maybe have to restart my CMD command prompt and let's say we and you can see that we got the node version so note version is 13 point I didn't which then which is the current release so you can use that ok now once you've got node and I mean depend upon when you are watching this video maybe have take after one year you might be having a new version so even if you have a new version it might work the thing is it goes for three different releases and not three different version systems in fact we'll talk about that in detail later but we have the bug fixes which so the last part will change depending on the bug fixes the middle part will change based on the money increments and the first part will change depend upon the measure increments and whenever you get a minor increment or patches it will not change much in the system but yes if you have a major version it might be having some new features it might remove the old features so you need to check those things as well okay now once you got node of course we want to write some code we want to run the first code of course whenever you learn a new language a new framework or a new tool the first thing you do is you don't hello world we want to do that here first but of course will not be doing that in this video but we need some Sophos for that where do you like your code and for that you need a editor you can use notepad as well okay but we'll be using some advanced editors which is one of them is vs code in this machine I do have vs code and if you want to install vs code just go to Google search movius code that's the website download this setup it's very easy to install the Avs will actually click on download for windows and it will do the installation now how it looks like so I do have the vs code set up here let me open that and that's how vs code looks like which is visual studio code this this is where you can create folders you can create files and you can run it in fact you can use envious code for all different programming's for all different frameworks it supports majority of them so you can use it so that's it from this video if you have talked about how to install node and how to install vs code in fact they are not in this relation of BS code do you know how it works so that's it from this video in the next video we will see the first code or will write a lot of oil we'll do some addition of two numbers just to understand how this Tool Works so that should be one bye bye see you next video
