Layout clientLoader is called on every URL change in SSR: false (SPA mode)

[Stephan-MDD]

In my Remix project with ssr: false (SPA mode) I have a clientLoader in a layout that is called whenever the URL changes. Navigating from index to foo and vice verse calls the loader an delays the navigations.

What I would expect was the loader function was called a single time on the initial rendering of the layout. Like it does using plain react router.

I created two projects that should be somewhat identical but with remix and react router. If you see the logs you would see loading... every time you navigate in the Remix project and only twice (StrictMode) in the React Router project.

Sorry for the slow video it got slow after converting it to GIF

I have a repo where you can recreate it :)

Hope it makes sense - thanks for Remix and React Router💙

export const shouldRevalidate: ShouldRevalidateFunction = () => false; was the solution :)
