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.
