Set Variable to result of Mongoose Find

Question

I\'m trying to do something like this

    function retrieveUser(uname) {
      var user = User.find({uname: uname}, function(err, users) {
        if(err)

Basically, MongoDB and NodeJS have asynchronous functions so we have to make it to synchronous functions then after it will work properly as expected.

router.get('/', async function(req, res, next) {

  var users = new mdl_users();
      var userData = []; // Created Empty Array
      await mdl_users.find({}, function(err, data) {
        data.forEach(function(value) {
          userData.push(value);
        });
      });
  res.send(userData);

});

In Example, mdl_users is mongoose model and I have a user collection(table) for user's data in MongoDB database and that data storing on "userData" variable to display it.In this find function i have split all documents(rows of table) by function if you want just all record then use direct find() function as following code.

router.get('/', async function(req, res, next) {

  var users = new mdl_users();
  var userData = await mdl_users.find();
  res.send(userData);

});
