[elm-discuss] Embedding the same view multiple times on a page

[Anthony Naddeo]

Does anyone have any pointers for how to repeatedly embed an Elm view on a
page, particularly from JS? The use case would be for some type of embedded
widget that people can insert into their page where each instance would
correspond to a different id of some type. Imagine a widget that embeds
live updating twitter feeds for different users where web page owners would
be able to create buttons that launch live update windows.

What have you tried and what problems did you encountered?

Here are 3 counters embedded in the same page with different info passed
through flags.

Why wouldn't something like this work?

That's actually very close to what I tried, I'm not sure what I was doing
wrong. I might have left some assumptions in about how many would be on the
page, but I wasn't getting any rendering.

Assuming I get that to work, what does embed actually do? Is each instance
totally isolated? Does the elm runtime bootstrap itself each time? To share
state, we'll have to use ports?

To my understanding, each instance is isolated.
I don't think there is a way to actually share state but you can keep the
state in various embeds synchronized by using ports.
