Can we start using it in production?

[afidegnum]

Hi,

what's the status of this project? can we start to use it in production?

It's still in an "alpha" status. Things are pretty stable, runtime-wise, but we're still making significant changes, including those that change the API, and we cannot promise to keep things backward compatible at this point.

So, if you have an interest in using it, trying it out and reporting issues (from bugs to usability issues) is helpful. Whether you use it in production is up to you, but be aware that things might break and need changes when you update Flexx.

What's the milestore? what needs improving so if possible, i can contribute? how can this be integrate to other frameworks like flask, etc... ?

We don't have a 1.0 milestone yet. But with each release we should be closer to stable-ness.

Here are some issues that I think are important missing parts, or can potentially introduce API changes:

• There might be some API changes related to mouse/pointer events Make "mouse" events work on mobile devices #149
• PyScript performance should be improved (at least allow it to run real fast), probably no API changes though PyScript performance #104
• We've seen Flexx to not work on Chrome in certain cases because we use eval Formalize the communication protocol (no more eval) #65
• At the moment the support for the notebook is rather unstable.
• If you need to send (large) data to the client, that's still something we need to figure out Provide means to send large (binary) data between Python and JS #143
• We don't have an awful lot of widgets yet. We basically add them when needed. Mo widgets #111
• Better debugging support on the JS side. More detailed logging for "debug mode" #179

how can this be integrate to other frameworks like flask, etc... ?

Flexx runs on Tornado, so I suppose you'd do it in a similar way as integrating Tornado with flask. Though if you have a choice, the easiest approach might be to just use Tornado.

Small update: Flexx should get beta status with v0.6, though I'll try to get most things that cause severe backwards incompatibilities in v.0.5. With beta I mean we take better care of backwards incompatibilities and deprecation paths.

[afidegnum]

sure, still watching the update, i m very interested in it,

[afidegnum]

have you think of blending or adding ELM ? that will make interacting with Javascript painless.. you can look at it at Elm-Lang

[almarklein]

have you think of blending or adding ELM

No. Are you suggesting to transpile Python to Elm and then to JS? What would the advantage be?

Actually, TypeScript might be a better target in that case, I guess. Though when WebAssembly becomes available, I could see us target that.

[afidegnum]

no, rather Elm to Js

[almarklein]

But there is hardly any JS in Flexx. Everything is transpiled from Python :)

Closing this. Flexx is nearing a release that brings it to Beta status. Not quite "production ready", but a step closer to it.
