How To Execute Windows Shell Commands (Cmd.exe) with Node JS

I would like to

C:\>ACommandThatGetsData > save.txt

But instead of parsing and saving the data in the console, I would like to do the above command with Node.JS

How to execute a shell command with Node.JS?

You could also try the node-cmd package:

const nodeCmd = require('node-cmd');
nodeCmd.get('dir', (err, data, stderr) => console.log(data));

On newer versions of the package, the syntax changed a little:

const nodeCmd = require('node-cmd');
nodeCmd.run('dir', (err, data, stderr) => console.log(data));

It does not support Promises directly, but you can easily wrap them inside one:

const nodeCmd = require('node-cmd');
const promise = new Promise((resolve, reject) => {
    nodeCmd.run('dir', (err, data, stderr) => {
        if (err) {
            reject(err);
        } else {
            resolve(data, stderr);
        }
    });
});
