Events in Node.js

  • Every action on a computer is an event.Like when a connection is made or a file is opened.
  • Objects in Node.js can fire events,like the readStream object fires events when opening and closing a file.
  • Node.js has a built-in module,called "Events",where you can create-,fire-,and listen for- your own events.
  • To include the built-in Events module use the require() method.
  • In addition,all event properties and methods are an instance of an EventEmitter object.
  • To be able to access these properties and methods,create an EventEmitter object.
  • example:emit()
