Reference error on node.js while include file

Question

I\'m new to node.js. i have two files. they are index.js and db.js

my index.js is

var connection =          


        

Answer 1

if you want something from the db module to be accessible in other modules, you need to expose it, by using module.exports

add to the end of your db.js file:

module.exports = {
  appModel : appModel,
  Device : Device
};

and then in your index.js you can do:

device = new connection.Device({
  id: 93,
  name: 'test1'
});

Answer 2

node.js treats every file as a module. so to include any source file into another you need to export it at the source end and import it using require at the importing file.
