Description

New feature docs for withastro/astro#4986

Add API reference for endpoint context

The docs are pretty simple for now. Let me know if there's anything that can be improved!

Once the heading names are confirmed, I'll also update withastro/astro#4986 to have the JSDoc point to the anticipated link.

Hey, this looks great!

I noticed that params is missing from the API reference. Also, is props available now? If so, we need to update the endpoints page where we say that props isn't passed to endpoint functions.

Yeah I saw params is missing for Astro.params too and it seems to be only documented in getStaticPaths(). I can try to document that too.

Also, is props available now? If so, we need to update the endpoints page where we say that props isn't passed to endpoint functions.

Yeah it's available now! I'll update this i the endpoint page 👍

Oh actually looks like there's the sentence in the endpoint docs:

Everything described in the static file endpoints section can also be used in SSR mode

So I think we don't need to add extra docs. params should work in SSR too with the PR.

I also pushed changes to add types and the code example for context destructuring.

Thanks @bluwy! Made some suggestions following up on my review of withastro/astro#4986

I made some assumptions that were maybe wrong judging by your final addition here… If so, maybe we need to make a note to document getStaticPaths in SSR which I didn’t think was supported.

[bluwy]

Applied the suggestions. Thanks for the thorough review!
