How to execute shell commands in Javascript

Working in Javascript apps, you might have to use shell commands to retrieve some informations or execute some treatments.

So here is the snippet to do it!

Code

const childProcess = require('child_process');

async function sh(cmd_to_execute) {
    return new Promise(function (resolve, reject) {
        childProcess.exec(cmd_to_execute, (err, stdout, stderr) => {
            if (err) {
                reject(err);
            } else {
                resolve({stdout, stderr});
            }
        });
    });
}

You can use this function which will return you the result of the command.
