some observations / enhancement request #3

Thanks for sharing this example.

I tried using your example code and have a few observations that I would like to share with you.

  1. I think we should make "offset" a user input.
  2. For the case when input "limit" is greater than the number of messages within the selected topic, the explorer is stuck in "Loading" state. I can see that it gets the messages from the backend, but since the messages are less than the requested limit, it just sits there for a timeout to occur and eventually error's out.

Please let me know your thoughts.

Based on your feedback, I am looking forward to add a few things to this example and will be happy to share an updated version with the community.

BTW I am using the latest versions of the following packages. "@loopback/authentication": "^5.0.0", "@loopback/authentication-jwt": "^0.5.0", "@loopback/authorization": "^0.6.4", "@loopback/boot": "^2.4.1", "@loopback/core": "^2.9.3", "@loopback/extension-health": "^0.4.11", "@loopback/extension-metrics": "^0.3.11", "@loopback/repository": "^2.11.0", "@loopback/rest": "^6.0.0", "@loopback/rest-crud": "^0.8.11", "@loopback/rest-explorer": "^2.2.8", "@loopback/service-proxy": "^2.3.6", "kafka-node": "^5.0.0",

@argupta23 Maybe you should checkout https://github.com/spirAde/loopback4-kafkajs-extension

Thanks for sharing. It looks interesting but is still in the very initial stages.

Pls. don't get me wrong. One of the concerns with extensions is that many a times they are not updated, so you are kind of stuck. I will continue to keep an eye on that package.

One of the things I want to do is to add support for socketio to your current example. I will try to take a stab at it over the weekend and will reachout to you for help.

If you already have something along the lines of Kafka + Socketio integrated together, I would he happy to use that and not start from scratch.

Thanks

@argupta23 I agree that your scenario is not uncommon. We have been exploring possible LoopBack extensions to support the messaging related use cases.

Unfortunately the progress has been slow due to our constrained bandwidth.

Appreciate the pointers I will look into them. I am willing to help you folks out by integrating some of the many silos that exist today.

Please let me know how I can help the team out.

Relative to the initial ask, I have already taken care of point 1. Can you please share some thoughts on how one would deal with point 2?

Thanks
