Feature request: friendlier error for empty bracket pair in template instead of full js_parse_error being thrown.

[UltraCakeBakery]

Describe the problem

When working in large svelte components in svelte kit, the console is flooded with the entire components json representation when a is_parse error is thrown by the compiler caused by a simple empty bracket pair:

look at the size / position of my scrollbar:

Describe the proposed solution

A custom error for this edge case, just saying "empty brackets not allowed in template.", or have it just strip it during compilation instead of throwing.

would make my life easier

Throwing a different error would not help. The error would still be thrown in the same way by vite-plugin-svelte...i'm gonna transfer this issue to the other repo in case @dominikg has better ideas but i think at the same time having the plugin code could be very useful when debugging some error that could be introduced by preprocessors or other plugins.

I don't think we should change anything here

Agreed...the only thing i could see feasible is maybe an option for vite-plugin svelte

Also i can't transfer it there 😄

[dummdidumm]

I'm gonna go ahead and close this - yes it's a big error but it's very detailed, and forgetting content in your braces does not happen that often

[UltraCakeBakery]

I would not have made this issue if it didn't happen that often.

But ok.

hmm, vite plugin svelte should format the frame and message more nicely on the console.

did something change with CompileError recently?

This has been a thing for months. Maybe the example I provided has changed recently, but I have been seeing this happen for a while now.

[dominikg]

lets see if we can make the terminal output nicer again. It's correct that the svelte error contains the full information but we shouldn't put json on the console like that

Thanks for looking into this ❤️
