Two-way bindings between Webview and Rust Yew

How can i call the invoke_handler from a Yew application? I want to communicate between Yew and Webview. I already tried adding javascript to Yew through stdweb and then calling external.invoke("foo"). But this doesn’t work.

I also took a stab at it (taking a lot of inspiration from the discussed approach): https://github.com/hobofan/yew_webview_bridge (also available on crates.io)

A few notable points:

• On the yew-side, I packaged the core logic into a service, which I think is a bit more of a idiomatic approach for yew
• How the user wants to handle their “shared” message types is left up to them
• The communication logic internally uses a Message wrapper type which carries a subscription_id and message_id, which allows for association of responses to their initial messages (this is handled by the service)
• When you use .send_message from yew, it returns a MessageFuture with the response from web-view (which can be used to trigger a component update with the included send_future helper).
