Use pty with ssh2 in node to execute command with sudo

Question

I need to launch a command with sudo over ssh using npm ssh2 module for node.js; only reading module's documentation I can't figure out how to use the pty option:

ssh.on('ready', function() {

    //not working sudo command:
    ssh.exec('cd /var/www/website && sudo mkdir myDir', { pty: true }, function(err, stream) {
        if (err) throw err;

        stream.on('exit', function(code, signal) {

            console.log('exit code: ' + code + ' signal: ' + signal);

            ssh.end();
        });
    });

}).connect({
    host: configuration.sshAddress,
    port: 22,
    username: configuration.sshUser,
    password: configuration.sshPass
});

Can someone explain the correct use of this?

You have to parse the stream output for the sudo prompt. At that point, you have to stream.write(password + '\n');. The alternative to doing all of that is to modify /etc/sudoers so that the logged in user can execute sudo for a specific program/script/whatever without a password.

I can't get this to work. How/where do I add the `stream.write(password + '\n');` – user1513388 Nov 03 '17 at 17:01

I think you should place the stream.write(password + '\n'); right after the stream.on('exit',.... line.
