Is it a bad practice to call `useQuery` in route components?
I wonder why we need
loader in the first place.
Can we just call useQuery and call it a day?16 Replies

you can certainly to so
however you won't benefit from preloading

So the benefit of using
loader instead of useQuery is loading data before rendering route components?sunny-green•7mo ago
not the only one but yes

Thanks, would you point me to docs where I can find other benefits of loader?

So that is really useful for preloading to have loader. Because when you hover over link the loader function is executed as I understand, right? Not only route js bundle is fetched but data it needs too.

Which means, I hover over a link to PageA then
loader on PagaA route is called automatically?metropolitan-bronze•7mo ago
Yes, when you have preload set to intent in your config.
That seems petty nice stuff. Just adding preload intent and loaders to your routes and your website feels fast as hell

Good to know, thanks @Valerka !
Oh shoot, doc haywire is still ongoing. Asking for related docs is a bad idea.
sunny-green•7mo ago
not sure if we have docs about that explicitly .
there are a few APIs that make more sense with loaderdata
e.g. head()

I'm gonna look up for
head() and tinker with it, thanks again!
Default preloadStaleTime is 30secs but default staleTime is 0. So even I preloaded data for a route when I move to the route within 30 secs loader is called again.
What's the meaning of this?sunny-green•7mo ago
meaning is that you will be able to instantly show the data
but the data might be stale
so it fetches it again in the background
and updates if it changed
vicious-goldOP•7mo ago
Ahhh
So when I move to the route, it shows preloaded data anyway and then run
loader to fetch the latest data, shrewd!sunny-green•7mo ago
yes

@Manuel Schiller Thanks to you, I have finally finished my TSR 101 tutorial.🎉
sunny-green•7mo ago
what does that mean? you created a tutorial?
vicious-goldOP•7mo ago
Yes, it's in Japanese though.
Now I can sell TSR hard here in Japan.
