Execute Powershell script from Node.js

You can just spawn a child process "powershell.exe" and listen to stdout for command output and stderr for errors:

var spawn = require("child_process").spawn,child;
child = spawn("powershell.exe",["c:\\temp\\helloworld.ps1"]);
child.stdout.on("data",function(data){
    console.log("Powershell Data: " + data);
});
child.stderr.on("data",function(data){
    console.log("Powershell Errors: " + data);
});
child.on("exit",function(){
    console.log("Powershell Script finished");
});
child.stdin.end(); //end input

The newer way to do this

const { exec } = require('child_process');
exec('command here', {'shell':'powershell.exe'}, (error, stdout, stderr)=> {
    // do whatever with stdout
})

In addition to the accepted answer, there is a Node.JS Library called Edge.js that allows various langugages to be executed from within Node. Including C#, J#, .Net, SQL, Python, PowerShell and other CLR languages.

Note that Edge.js requires PowerShell 3.0 & only works on Windows (many of the other features work on Mac and Linux too).

Or you can just use Node-PowerShell.

Node-PowerShell taking advantage of two of the simplest, effective and easy tools that exist in the today technology world. On the one hand, NodeJS which made a revolution in the world of javascript, and on the other hand, PowerShell which recently came out with an initial open-source, cross-platform version, and by connecting them together, gives you the power to create any solution you were asked to, no matter if you are a programmer, an IT or a DevOps guy.
