Dash and Standard Webapp

Hi community,
I am currently using 13.4V of Dataiku where I don’t have access to the API services.
About my Agent Code:
I have created a multi-agent system in Python where each agent performs a specific task sequentially:
Agent 1 – Searches for relevant content based on user input.
Agent 2 – Extracts the required context from the searched data.
Agent 3 – Summarizes the extracted context.
Agent 5 – Validates the response for quality.
Each agent runs one after another, and I want to show progress updates in real-time on the frontend (like a progress bar or message saying “Agent 1 working...” etc.).
Example:
While Agent 1 is working, I want the UI to show: Agent 1 is working... [25%]
Then, once it completes, the progress bar should update: Agent 1 completed.
I tried implementing a live progress bar using a Dash Webapp, but I ran into limitations. Since Dash doesn't fully support asynchronous mechanisms, I attempted workarounds using Interval, dcc.Store, and Python threading, but none gave me the desired result. I'm not sure what’s going wrong.
Now, I am exploring the Standard Webapp instead. But since I can't use backend APIs(like @app.route or dataiku.webapp), I’m struggling to show these updates live in the UI. Currently, the frontend only shows the final result after all agents finish.
My question is:
- Is it possible to implement a live progress bar in a Standard Webapp without using API services? Or do we absolutely need backend API support (e.g., dataiku.webapp or @app.route) to achieve this?
- In Dash webapp - is it possible to use live progress bar?
- Any other ways?
I'd love to hear if anyone has achieved something similar without relying on APIs. Any insights or alternate approaches are welcome!
Thanks in advance
