Request for library: mpsc channels library built on top of the postMessage API

[fitzgen]

This could allow wasm to talk to js via CSP style message passing, different wasm instances to talk to each other without sharing memory, the wasm instances might even be in different threads by using web workers.

Would be awesome to see someone experiment with this by making a library!

Is there any existing attempt for this library?

None that I am aware of!
