What is the process for defining the host in a websocket connection?

When working on my page, I establish a websocket connection to the server using ws://127.0.0.1:5000/ws in development and ws://www.mymachine.com/ws when deployed to production. Is there a more efficient way to handle this so that I don't have to manually adjust the URI from 127.0.0.1:5000 to www.mymachine.com every time I deploy?

I attempted to use ws://ws but it was unsuccessful. My goal is to achieve similar functionality as a standard URL where you can simply use /index and be directed to either 127.0.0.1:5000/index or www.mymachine.com/index based on the environment it is running in.

Answer №1

Dealing with a comparable issue, I found a solution that worked for me:

 let url = window.location.host + window.location.pathname + 'socket'
  if (window.location.protocol === 'http:') {
    mySocket.connect('ws://' + url);
  } else {
    mySocket.connect('wss://' + url);
  }

Answer №2

Consider adding a single variable at the beginning of your script for initialization purposes. For additional functionality, explore the benefits of utilizing the File API - A URL for Blob and File.

The File API specification introduces URLs in the format:
blob:550e8400-e29b-41d4-a716-446655440000#aboutABBA.

These URLs are stored in a designated URL store, allowing browsers to potentially have their own embedded mini HTTP server for usage in CSS, image sources, and even XMLHttpRequest.

To implement this within your initialization script, consider using an if/else statement to construct your URL object and add it to the store. For more guidance, refer to this answer. (Additionally, compatibility concerns may be less relevant when utilizing web sockets.)

Hopefully, these insights inspire new ideas for your project.
