actually it looks like this can be a tsx file in Storybook 9. I'm gonna upgrade us.

Weren't used at all

This ends up being more important for the upcoming PR, but I really, really think that we need to find the time to formalize our entire data layer, and be way more deliberate with our React Query caching

I fully expect our caching to create a super, super hard-to-recreate bug sometime in the future, because it's a bunch of semi-structured global mutable state right now

Also added an explicit string type annotation so that TypeScript doesn't over-infer the value and treat it as a literal. We shouldn't know what exact combination of characters it is – just what purpose the string serves in the greater codebase as an opaque value

I am very interested to hear you elaborate on all of this because I am not sure I follow. 😅

nit: there seems to be inconsistencies within the code base between using camelCase or UPPER_SNAKE_CASE for file-wide constants so while out of scope for this PR I think deciding on one and sticking to it would be good

Yeah, that's fair. The JS/TS way seems to be SCREAMING_CASE for constants, while the Go way seems to be to treat them as any other package value

I'm leaning towards switching this to SCREAMING_CASE, but I'll wait for Kayla to chime in

I prefer to just name them like normal variables personally. an example of why in this context is that for an actual constant key vs a function that returns the key we get...

const aQueryKey = ["a"];
const bQueryKey = (id: string) => ["b"];

({ queryKey: aQueryKey });
({ queryKey: bQueryKey(bId) });

a small benefit of this aside from the visual consistency is that if a query key ever needs to go from truly constant to a function the amount of typing required is slightly smaller.

I think SCREAMING_CASE served more of a purpose in the days before LSPs. now it's just so much easier to tell what something is and where it's defined.

Decoupled type signature from React Router. Splitting this up gives us a lot more freedom, which comes up later in this PR

I feel like the previous type was super, super risky, because it was derived from a function that didn't have much type-safety

With this, the contract is way more explicit and simple, and there's basically no chance of the TypeScript LSP getting confused and dropping properties for tooltips

We were missing a return type altogether before

Another render optimization

What is this render optimization? Not re-rendering the page if it's the same page?

So there's two parts:

• The basic input validation from the Number static methods
• The equality check

I could maybe add a comment, but React only has Object.is for change detection, so in general, a lot of render optimizations boil down to "only dispatch a new value (especially a non-primitive value) when you know the contents have changed". Most of the time, you don't have to worry about over-dispatching primitive values (as long as they're done outside a render, React will detect that nothing changed and do a no-op for the state update). But because JS is wacky, there are edge cases with Object.is and numbers, which is why there's the extra === check

wdym edge cases with Object.is? the only "edge case" I'm aware of is Object.is(0, -0) === false

⚠️ Potential issue

Critical bug: setting wrong page value

The goToPage function has a bug where it sets the current page instead of newPage. Also, the validation should check newPage instead of page.

Apply this fix:

 goToPage: (newPage) => {
   const abortNavigation =
-    page === newPage || !Number.isFinite(page) || !Number.isInteger(page);
+    page === newPage || !Number.isFinite(newPage) || !Number.isInteger(newPage);
   if (abortNavigation) {
     return;
   }

   const copy = new URLSearchParams(searchParams);
-  copy.set("page", page.toString());
+  copy.set("page", newPage.toString());
   onSearchParamsChange(copy);
 },

In site/src/hooks/usePagination.ts around lines 29 to 39, the goToPage function
incorrectly validates and sets the current page variable instead of the newPage
parameter. To fix this, update the validation conditions to check newPage for
finiteness and integer status, and set the "page" query parameter to
newPage.toString() instead of page.toString() before calling
onSearchParamsChange.

The extra wrapper function was redundant

Removed type assertion to remove risk of accidentally silencing the compiler

better yet can we just get rid of the reduce here?

	const initialTouched = Object.fromEntries(
		parameters
			.filter((it) => autofillByName[it.name])
			.map((it) => [it.name, true]),
	);
