Is it possible to execute command line/powershell commands from a svelte backend?

I'm looking to get a list of windows services on a machine on my network. Running a powershell command would be how I achieve this normally, but can I do this from a backend of a sveltekit app? Perhaps a server or api file? If so, how?

You can execute any valid code for the given backend, which by default should be NodeJS. So it is just a question of how to do that in Node.

The module child_process has various functions for starting new processes, e.g.

// +page.server.js
const { exec } = await import('child_process')

export const load = async () =>
{
	const computerName = 'localhost'
	const stdout = await new Promise((resolve, reject) =>
	{
		exec(
			`powershell -command "Get-Service -ComputerName ${computerName}` +
				'| Where-Object -Property Status -EQ -Value Running' +
				'| Select-Object -Property Name"',
			(err, stdout) => err ? reject(err) : resolve(stdout)
		);
	});

	const items = stdout.split('\n')
		.map(x => x.trim())
		.filter(x => x)
		.slice(2); // removes table header

	return { items };
}
