Node.JS Nodejs and Express

[new2Nodejs]

I'm beginning to learn JavaScript and determined that development is better with Nodejs. So, I got hold of "Jump Start Node.js" by Don Nguyen and started to work my way through it. I've installed Node.js on my Windows 10 system, organised a MongoDB on AWS, then I'm asked to do the following:

sudo npm install -g [email protected]

There was no indication whether this was to be done in Node or the command shell. I found that Node doesn't know what 'npm' is and the command shell doesn't know what 'sudo' is.

So, I'm lost. Can anyone help?

Hi there,

That is because sudo is a Unix/Linux based command to allow a user temporary admin/root privileges. Windows doesn't have that. You would have to right click the command prompt icon and select "run as administrator" and click on yes when the warning popup shows up.

Here's a very helpful guide on how to install node and npm on windows:

In this article, you'll learn how to work with JavaScript in the backend using Node on Windows. When you start working with JavaScript and discover that you can not only work with it in the frontend but also in the backend, a new world of possibilities seems to open up

Thanks for the reply. When I right-click to run the command prompt as admin, enter the command and press enter, it responds with 'sudo' is not recognised as an internal or external command, operable program or batch file.

Hey @new2Nodejs

What if you tried the command without using sudo? Does anything else pop up?

I think you misunderstood what I mentioned. I was saying that sudo, the command that gives a user temporary admin privileges, is not a Windows Batch/Command Prompt command. That is a command found in UNIX/Linux based systems. Windows way of getting privileges, is to right click on the icon and click on "run as administrator" and click ok on the warning pop up.

Thanks Antero360...I did read your response. I said 'admin' as a shortcut to 'administrator' which I used.

As for your 'freecodecamp' insert...excellent! I followed it and have Node, npm and Express installed. I have a test package.json sitting in VS, is it executable?

It should be

I agree, but nothing in the "Test" tab of VS does anything.

Did you try opening the developer terminal in VS, and doing "npm run"?

Thank you, that worked!

Thank you, that worked!

Glad to hear it's working as intended 🙂
