Node.js exec event not firing inside Promise

I have this simple code which is a promise as you can see:

var exec = require('child_process').exec;

return new Promise(function(resolve, reject) {

        var x = exec(`cd /maps && ls -la`, {}, function(err, stdout, stderr) {

            if (err || stderr) {

              reject(err + stderr);
            }

            resolve(stdout);
          });

          x.stdout.on('data', function (data) {
            console.log(data);
          });
    });

The on event is never fired while if i remove promise from around everything works

do you have any clue?

Try moving your resolve out of your callback function, and call it after console.log(data).

The reason may have been because you were resolving your promise too early.
