//sensor1.js
var distance = 0
function getDistance(){ return distance }
module.exports = { getDistance : getDistance}
in your server.js
var sensor1 = require('./sensor1.js')
sensor1.getDistance()
don't call it class, it is not a class. even with the constructor function.
we have a name for it, it's module. modules have scope: everything defined
in them with var of function statement is private, everything you
add/assign to module.exports object is public. all functions defined in the
module share the module scope and cann read/manipulate things in this scope
(pretty much like class scope)
if you need more than one instance of your module, export a constructor or
factory function and wrap the instance vars in it:
//sensor1_notSingleton.js
function Cons(){
this.distance = 0
}
Cons.prototype.getDistance = function getDistance(){ return this.distance }
module.exports = Cons
