Just noting here that we want to make all code blocks copy/paste and it's working code. We try not to put multiple options in a code sample that would make it not run as-is.

There's a lot going on in this whole snippet. Can ALL of it happen together in a working function? e.g. "throw an Astro error or handle it yourself" If these can't be done together, then instead one of them could be commented out entirely e.g.

// Or handle errors yourself
// return Astro.redirect('/500');

And, the same goes for e.g. defining entries in multiple places. I know it's convenient to throw everything in one block, but I think we might need another pattern here if this, as a whole, isn't functioning code.

I've had it hammered into me to use Oxford comma for Astro stuff, so isn't this right as it stands? I think I'll reword this anyway though

Yes, I'm not sure why Yan would remove an Oxford comma. Chalk it up to exam week brain, unless there's something I'm missing? 😄

So fine as is, I think!

It's probably the thing I find hardest to remember when writing Astro stuff! Even harder than using US spelling, because at least that's obvious.
