node powershell

To execute PowerShell commands using Node.js, you can make use of the node-powershell module. Here is an explanation of each step involved in using this module:

1. Install the node-powershell module by running the following command in your Node.js project directory:

npm install node-powershell

This command will install the module and its dependencies.

1. Require the node-powershell module in your Node.js script:

const PowerShell = require('node-powershell');

This line imports the node-powershell module and assigns it to the PowerShell variable.

1. Create a new instance of the PowerShell class:

const ps = new PowerShell();

By creating a new instance of the PowerShell class, you can interact with PowerShell commands.

1. Execute PowerShell commands using the addCommand() method:

ps.addCommand('Get-Process');

This line adds the Get-Process command to the PowerShell instance. You can add multiple commands by calling the addCommand() method multiple times.

1. Invoke the invoke() method to execute the added commands:

ps.invoke()
  .then(output => {
    console.log(output);
  })
  .catch(err => {
    console.error(err);
  });

The invoke() method performs the execution of the added commands. It returns a promise that resolves with the output of the execution. In this example, the output is logged to the console. Any errors that occur during the execution are caught and logged as well.

1. Finally, close the PowerShell instance:

ps.dispose();

This line closes the PowerShell instance and frees up any resources it was using.

These steps outline the process of using the node-powershell module in a Node.js script to execute PowerShell commands.
