In Node.js, how to import functions from another JavaScript file?

In Node.js, how to import functions from another JavaScript file like source common.sh in Bash?

In the .js file to be imported such as ‘common.js’, organize functions to be exported like

module.exports = {
  func1: function () {
    // func1 impl
  },
  func2: function () {
    // func2 impl
  }
};

In the other .js files, you can “include” the ‘common.js’ by

var common = require('./common');

In the following code, the functions can be used like

common.func1();
