Execute Powershell script from Node.js

Question

I've been looking around the web and on Stackoverflow but hadn't found an answer to this question. How would you execute a Powershell script from Node.js? The script is on the same server as the Node.js instance.

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
