working vega component that support altair charts and vega dict

[LeoGrosjean]

This is still work in progress

You can check @Alek99 my issues with how events should work

I will remove all comments and TODOs

I have an issue with serializer, I will open a ticket / PR to allow serializer overwrite

[Alek99]

Thanks for making the PR! Can you separate the Vega and Altair into different folders and make them separate PRs. We will publish them separately as different packages

[LeoGrosjean]

Hey @Alek99 !

I'm still working struggling on :

• signal_listeners
• on_new_view

Props on_new_view

onNewView={(view) => {
   view.addEventListener("click", (_e, item) => console.log(item)); # state event instaid !
   view.addEventListener("hover", (_e, item) => console.log(item)); # state event instaid !
 }}

As asked, I renamed custom component as altair only to keep only python and avoid custom js !

[LeoGrosjean]

I added support for onNewView

It get construct from those props :

on_new_view_click
on_new_view_dblclick
...
on_new_view_dragleave

Sadely page reload and all selection are removed when event is trigger (big charts can also flash)

[LeoGrosjean]

All flashing and page reload has been fixed !
Altair is ready to be used at his max potential in reflex !
