Get return of asynchronous callback insince module export nodejs- Nodejs

Server:

require('./MovimientoJugador')();
var camino4=MoverJugador(startX,startY,endX,endY,mapa2); 
console.log("Camino: " + camino4);

ClientMovimientoJugador:

module.exports = function() { 
  var Camino="uno";
 this.MoverJugador = function(startX,startY,endX,endY,mapa) {
easystar.findPath(startX, startY, endX, endY,function( path ) {
Camino=JSON.stringify(path);
 console.log("C:" + Camino)
 return Camino;
}}

Console:

Camino= uno
C=(X:1,Y1)(X2:Y2) etc...

The variable Camino has the value of one when declared. At the time that the server shows it, it does not give you time to show the last return value.

How could I turn this into a promise or make a wait of x seconds?
