Fetch RequestInit method parameter issue

[TomiS]

Hey, I'm not sure if this is a ReScript 11 thing or something else, but in order to make fetching work properly, I needed to change this line and this line in such way that neither have underscore as prefix

e.g.

~_method: string=?,

=>

~method: string=?,

The current implementation does not work when using DELETE as method (at least). It causes an error
TypeError: Failed to construct 'Request': Request with GET/HEAD method cannot have body.

Yes rescript-lang/rescript#6354 removed _ mangling; in earlier compiler versions the _ prefix was introduced as a way to allow binding to JS names that were reserved words in ReScript. Now instead of _method compiling to method it's emitting _method. As a result your fetch call is not actually specifying a method and falling back to the default.

I'll try to find some way to fix this without breaking ReScript 10 compatibility. It would be a shame to need a breaking version change just for v11 support.

If I can't make it work I might just pull fetch out and link to rescript-fetch instead (the fetch support in webapi was pulled from glenn's bs-fetch which I thought was abandoned).

And the tests for both

Sounds good. Thanks for clarifying.

Edit: Though I think _type is still a keyword that needs to be mangled even in RS 11, right?

I didn't see your edit. That's... probably something I should've reported to the compiler team. Hmm.
