How to execute PowerShell script from Node.js?

Spread the love

To execute PowerShell script from Node.js, we call the spawn function.

For instance, we write

const spawn = require("child_process").spawn;
const child = spawn("powershell.exe", ["c:\\temp\\helloworld.ps1"]);
child.stdout.on("data", (data) => {
child.stderr.on("data", (data) => {
child.on("exit", function () {
  console.log("Powershell Script finished");

to call spawn to run powershell.exe with the path to the PowerShell script.

We listen for output by calling child.stdout.on to listen for data events.

We listen for errors by calling child.stderr.on to listen for data events.

And we call child.on with 'exit' to listen for process exit.
