How justpy handle websocket?

[kimgiftww]

I found this tutorial is very amazing as well as all of justpy. Never seen any python web framework so interesting as this. My question is how do I learn more about what justpy is doing under the hood such that we can implements websocket this easy? And so, hopefully, I could contribute something in the future.

I wonder whether we could do real-time streaming to update ag-grid with justpy? How do we implement pushing data to update the ag-grid instead of a justpy webpage? Is this the right question to ask here?

I'm currently using Dash which I considering replacing it with justpy for my team work on dashboarding with pure python instead of traditional BI tools. Dash AG-Grid is a dash enterprise component compared to the community offer in justpy. (Although many killing feature in AG Grid require enterprise license such as pivot and row grouping as well as charts)

Also not sure is whether updating AG Grid from justpy would invlove something like this:

@kimgiftww sorry for the late reply - i have been "on the road" in the past few days.
You are most welcome to collaborate in this project. Did you manage to run all the tutorial examples in a docker container?
Ther are also a-grid examples available. Justpy does the "websocket"- magic for you. If you'd like to dig into the technical details you are most welcome to do so. E.g. #483 might be interesting for you.

Hi wf,

Thanks for your reply.
I am trying to study how justpy work and so far I love it and think I could use it but just still don't understand how it work yet.
First of all, I found that #483 you suggested is indeed interesting and could help me understand what justpy is doing.
However, it is a bit beyond what I intend to use justpy with for now.

Specifically, what I am looking is how do we use justpy websocket to update ag-gird with particularly only the updated data. Is this what #138 trying to achieve or related to these 2 links ?

I could get most of the tutorial up and running with out docker and I even use Jupyter to run them.
However, more instruction here would be much appreciated for me to try justpy with docker.

Moreover, I think something is missing from the instruction in these below links
https://justpy.io/blog/vue_comparison/
https://github.com/justpy-org/justpy/blob/master/docs/blog/vue_comparison.md
https://github.com/justpy-org/justpy/tree/master/examples/blog/vue_comparison
for the Vue examples to work? as I only these empty buttons.

Lastly, it would be nice if examples/blog/tutorial could somehow be combined and indexed to align with their counterpart (docs/codes) for more convenient reference.
