Custom Events

Create your own events

Create custom events for component communication:

// Create and dispatch
const event = new CustomEvent("userLogin", {
  detail: { userId: 123 }
});
element.dispatchEvent(event);

// Listen
element.addEventListener("userLogin", (e) => {
  console.log(e.detail.userId);
});

Custom events let components communicate without tight coupling.
