How to get notified in JS that LiveView finished loading?

Hi,

We need to signal Cypress somehow that a LiveView page finished loading, which should ideally work across the whole platform.
It’s pretty easy with the navigation - we just tapped into the phx:page-loading-stop event.

window.addEventListener('phx:page-loading-stop', (info) => {
  if (window.Cypress) {
    window.componentsReady = true;
  }
}

But phx:page-loading-stop is not fired on an initial page load, and I wonder if there is another event for that?

TLDR: we are looking for an analogy of DOMContentLoaded for Liveview.

Thanks.

The LiveView documentation seems to imply that phx:page-loading-start and phx:page-loading-stop are triggered also by the initial page load, with the event detail set to "initial".

Right, it worked just fine on the live route in the fresh app.

Maybe it has something to do that we are using live_render to render LiveView component as we are loading different dashboard for different types of users on the /dashboard route.
