An option to disable the loading spinner

[zachcp]

Thanks Framework Team - this is really great.

Currently, unresolved promises show a rotating arrow as seen here. In some cases it would be nice to toggle the visibility for reactive in puts - e.g. don't show anything at all until the promise resolves. Maybe there is already a way to do that - in which case adding a bit more to the Promises docs would be quite helpful.

One way to do this is with a style:

.observablehq--loading::before {
  display: none;
}

Can you talk more about when/why you’d want to turn this off? Like, for a specific code block, for a page, or globally? I think it’s generally good to show that some computation is happening to the user.

You may also be able to bypass the spinner by not writing blocking code, but I’ll need to understand the use case a bit better to suggest a specific solution.

• I've been playin around with Tauri (RUST backend + any web-frontend) for making a compute-heavy bioinformatics-focused application.
• I want to do things like get stats on common bioinformatic files and make some graphs with Observable.
• I like the file-based routing as I can keep each little utility separate.
• a typical page might be a multipart form with a file-chooser (from Tauri) and a submit button.
• I'm trying to find more control over displaying outputs
