title: NodeJS: Is there a way by which i can save the value returned by a promise and can access this variable from another file
body: <p>I have a asynchronous function (a promise), which reads an xml file and give a map of keys and value, if the promise is resolved. I need this map throughout my project. So i want to read this xml file only once, probably at the start of my project and save the map in a variable. And i want to use the variable in different files of my project. Is there any way by which i can achieve this?</p>
