You can use the child_process API.
if (filename === ".tgz") {
const { exec } = require("child_process");
exec("npm install --save ../test/datemodule.tgz");
}

How to restart a node.js server
(9 answers)
Closed 3 years ago.
I created a sample node function like hello world. After being executed using the command line node myfirst.js, hello world displayed in the browser. After installing the nodemon it re-execute on small changes, but some times it became stuck and failed to recompile on major changes which needs to restarted. Do i have to install any other npm packages?
Use nodemon
Nodemon is a tool that helps develop node.js based applications by automatically restarting the node application when file changes in the directory are detected.
Install it with npm install nodemon -g
Execute your app with:
nodemon myfirst.js
Instead of using node myfirst.js
The solution will refresh every time you save your edited code.
I'm not sure I fully get what you need but you could try to use nodemon --> https://www.npmjs.com/package/nodemon
Hope it helps!

I have node installed however in my main terminal I cant access it. I can run the "Node.js command prompt" and it will work fine but shouldn't I be able to run node in the terminal?
You have to add the node parent directory to the system $PATH variable.

I had installed the node js, express js and npm to manage my application.
i have created the app using express js. Now I want to the run my express js app in command line in linux. currently i'm using DEBUG=alpha-webtorrent:* npm start to run my app.
I also want to run my app in background for forever.
In your command line run npm install -g pm2 cd o your app,lication and run pm2 start app.js viola your server will run forever and restart if a crash occurs. Documentation for pm2 is here
install a package called forever
npm install forever -g
Go through the documentation to know more about it.
https://www.npmjs.com/package/forever
And then use
forever start filename.js

nodejs vs node on ubuntu 12.04
(21 answers)
Closed 8 years ago.
I am using ubuntu 14.04 and when i use node hello.js command on terminal nothing happens. I installed the packages using sudo apt-get command. I don't know what is wrong. No error message or anything. I searched for my problem but couldnt find anything.
The problem has to do with package naming. The node package in Debian/Ubuntu is not node.js, it's amateur packet radio software.
My suggestion is that if you want node.js, remove the existing node program (sudo apt-get purge node for Debian/Ubuntu) and follow the instructions here for your particular distro/platform. That should get you the latest stable version, which you should be able to verify with node -v.
