this is take #2 of this PR https://github.com/tldraw/tldraw/pull/3764
This continues the idea kicked off in
https://github.com/tldraw/tldraw/pull/3684 to explore LOD and takes it
in a different direction.
Several things here to call out:
- our dotcom version would start to use Cloudflare's image transforms
- we don't rewrite non-image assets
- we debounce zooming so that we're not swapping out images while
zooming (it creates jank)
- we load different images based on steps of .25 (maybe we want to make
this more, like 0.33). Feels like 0.5 might be a bit too much but we can
play around with it.
- we take into account network connection speed. if you're on 3g, for
example, we have the size of the image.
- dpr is taken into account - in our case, Cloudflare handles it. But if
it wasn't Cloudflare, we could add it to our width equation.
- we use Cloudflare's `fit=scale-down` setting to never scale _up_ an
image.
- we don't swap the image in until we've finished loading it
programatically (to avoid a blank image while it loads)
TODO
- [x] We need to enable Cloudflare's pricing on image transforms btw
@steveruizok 😉 - this won't work quite yet until we do that.

Previously, we had the `ae-forgotten-export` rule from api-extractor
disabled. This rule makes sure that everything that's referred to in the
public API is actually exported. There are more details on the rule
[here](https://api-extractor.com/pages/messages/ae-forgotten-export/),
but not exporting public API entires is bad because they're hard to
document and can't be typed/called from consumer code. For us, the big
effect is that they don't appear in our docs at all.
This diff re-enables that rule. Now, if you introduce something new to
the public API but don't export it, your build will fail.

This PR uses an additional ArraySet to make capturing parent
relationships faster for computeds with more than a handful of parents.
Seems to result in an overall ~20% speedup of the `maybeCaptureParent`
function in normal usage.

This PR revamps how errors in signia are handled.
This was brought about by a situation that @MitjaBezensek encountered
where he added a reactor to a shape util class. During fuzz tests, that
reactor was being executed at times when the Editor was not in a usable
state (we had a minor hole in our sync rebase logic that allowed this,
fixed elsewhere) and the reactor was throwing errors because it
dereferenced a parent signal that relied on the page state
(getShapesInCurrentPage or whatever) when there were no page records in
the store.
The strange part was that even if we wrapped the body of the reactor
function in a try/catch, ignoring the error, we'd still see the error
bubble up somehow.
That was because the error was being thrown in a Computed derive
function, and those are evaluated independently (i.e. outside of the
reactor function) by signia as it traverses the dependency graph from
leaves to roots in the `haveParentsChanged()` internal function.
So the immediate fix was to make it so that `haveParentsChanged` ignores
errors somehow.
But the better fix involved completely revamping how signia handles
errors, and they work very much like how signia handles values now. i.e.
- signia still assumes that deriver functions are pure, and that if a
deriver function throws once it will throw again unless its parent
signals change value, so **it caches thrown errors for computed values**
and throws them again if .get() is called again before the parents
change
- it clears the history buffer if an error is thrown
- it does not allow errors to bubble during dirty checking i.e. inside
`haveParentsChanged` or while calculating diffs.

happened in #2322

[^1]: publishes a `patch` release, for devDependencies use `internal`
[^2]: will not publish a new version
One minor issue with signia is that it uses global state for
bookkeeping, so it is potentially disastrous if there is more than one
version of it included in a bundle.
To prevent that being an issue before we had a warning that would
trigger if signia detects multiple initializations.
> Multiple versions of @tldraw/state detected. This will cause
unexpected behavior. Please add "resolutions" (yarn/pnpm) or "overrides"
(npm) in your package.json to ensure only one version of @tldraw/state
is loaded.
Alas I think this warning triggers too often in development
environments, e.g. during HMR or janky bundlers.
Something that can prevent the need for this particular warning is
having a global singleton version of signia that we only instantiate
once, and then re-use that one on subsequent module initializations. We
didn't do this before because it has a few downsides:
- breaks HMR if you are working on signia itself, since updated modules
won't be used and you'll need to do a full refresh.
- introduces the possibility of breakage if we remove or even add APIs
to signia. We can't rely on having the latest version of signia be the
first to instantiate, and we can't allow later instantiations to take
precedence since atoms n stuff may have already been created with the
prior version. To mitigate this I've introduced a `apiVersion` const
that we can increment when we make any kind of additions or removals. If
there is a mismatch between the `apiVersion` in the global singleton vs
the currently-initializing module, then it throws.
Ultimately i think the pros outweigh the cons here, i.e. far fewer
people will see and have to deal with the error message shown above, and
fewer people should encounter a situation where the editor appears to
load but nothing changes when you interact with it.
