onUnmount() called outside of component setup

What happened

You called onUnmount() outside of a defineComponent() setup function. AkashJS needs an active component context to register lifecycle hooks.

How to fix

Move the onUnmount() call inside defineComponent()'s setup function.

Example

// Bad
import { onUnmount } from "akashjs";

function setupCleanup() {
  onUnmount(() => console.log("cleaned up")); // no component context!
}

// Good
import { defineComponent, onUnmount } from "akashjs";

const Subscription = defineComponent(() => {
  const ws = new WebSocket("/events");

  onUnmount(() => {
    ws.close();
  });

  return () => h("div", {}, "Connected");
});
