  • Are you always mystified, like me, whenever you come across words like Buffer, Stream, and binary data in Node.js?
  • When introducing Buffer, the official Node.js docs states in part… – … mechanism for reading or manipulating streams of binary data.
  • Extracting from that introduction, we could safely say: – The Buffer class was introduced as part of the Node.js API to make it possible to manipulate or interact with streams of binary data.
  • But… Buffer, streams, binary data… still many big words.
  • So from the original definition of a buffer (streams of binary data… in the context of… file system) this simply means binary data being moved in the file system.

  • Minute 3: Fork the SMS Handler SourcecodeNow that youve claimed your first MessageBird phone number, well walk you through the process of creating a handler that will respond to incoming SMS messages.
  • This function will receive events triggered by incoming SMS messages to your MessageBird number and will call other handlers a handler for incoming messages that contain the word more as their sole a not found handler.
  • If the incoming message can not be mapped to a named function (like more) this handler will be triggeredYou can test the outputs of your MessageBird hub for given input messages from your command line by running: – $ lib.
  • Minute 7: Testing YourHubTo test your new hub, simply send an SMS message to your claimed MessageBird number: – Some sample texts you can send to your new messagehubAnd thats it!
