Case-insensitive option

[jods4]

Is it possible to add an option to make sirv case-insensitive?

That would probably mean making the normalized path lowercase in FILES and doing the same on incoming path.

Motivation
Currently on Windows sirv behaves differently in dev mode vs not, because in dev mode every request is a file system check, which is case-insensitive on Win.
When you run the same folder from sirv static cache, it becomes case-sensitive and some requests suddenly fail.

Also it is common for some (but not all) web servers to be case-insensitive.

As expected, this breaks Linux systems running sirv without caching enabled. My initial impression is that this may be too fussy to accommodate

Without caching the implementation is a file probe, which is dependent on OS semantic (e.g. case-insensitive on Win, case-sensitive on Linux).

I agree that trying to change the OS semantics is a serious hassle.

What about just having an option to configure the cached behaviour?
The default value of this option could be set to the underlying OS behaviour, so that there's no discrepancy between dev and prod when running on the same OS.

It's not perfect as one cannot change the OS semantics without cache, but it's a nice improvement.
It improves consistency between dev/prod and enables new scenarios such as case-insensitive web server on Linux (with cache).

How about options.insensitive or options.lowercase

yeah it would do the job.
I'm not very good at naming things, myself 😕
