Is it possible for an island to interact with another?

[italodeandra]

Quoting from the documentation:

"islands" of interactivity, in a sea of otherwise static content

But lets say I want two islands to have the same state. How do I make them communicate with each other?

Pass events between them using window?

[italodeandra]

For now I'm using valtio for sharing the state and seems to work fine. But I'm still investigating and testing, not sure how well it will work on a real project in production.

Pass events between them using window?

I did this, now am using a state store: Statery which works a lot like a svlete store, and seems to work well even at moderate scale.

@italodeandra I did a write-up on this two days ago! How to use cross-island state management in Deno Fresh
TL;DR: use a state-management store.

Passing events or data around using window is prone to breaking, IME. You "reach outside" the app, IMHO there's too much risk of other outside colliding. Using a store and Preact/ React in a clean work is easier to maintain and test.

FYI: We now have a section about that in our docs https://fresh.deno.dev/docs/examples/sharing-state-between-islands
