Tips and tricks

Let's talk about some tips and tricks that you can use while making an application.

• Using JSON:

  The JSON format is an easily readable format in JavaScript. It is always good to transfer data in the JSON format.

• Object-based structure for WebSockets:

  Normally, in any application where we have to transfer different data sets, it is always preferred that we finalize a proper structure for the messages. Take the example of a chatting application: if we finalize a structure, it is better to handle the message. Here is a sample structure:

    {
      type: "message"
      data : {
        from: "varun"
        to : "user1"
        data : "hello"
             }
    }

• Using ArrayBuffer:

  There is another way to send data using ArrayBuffer; you can also send a Binary Large Object (BLOB). Here is an example of the same:

  var array = new Float32Array(5);
    for(var i = 0; i < array.length; ++i) {
      array[i] = i / 2;
    }
    ws.send(array, { binary: true, mask: true });

These kinds of structures can help in...
