Rendered more hooks than during the previous render Typescript error

Hey, I have a parameter on my page that im loading with with router.query. This is what my code looks like const { studentId } = router.query;

if (typeof studentId !== "string") {
    return null;
  } else { 
const studentQp = api.coach.getStudentQps.useQuery({
      studentId: studentId,
    });
rest of my code....

I did it this way to ensure typesafety, but if i put all of the trpc querys at the beginning of the page, i get typescript errors because the type of studentId is not checked first How do i solve this?

Inject react on a preexisting website for demo purposes

Im building a product that i want to demo for a client, its a little personal assistant. The product is built using react, and i would ideally like to host a version of their website locally, where i go on to insert my react code. Do you guys have any method that i could try to accomplish this? I tried using a proxymiddleware solution, but most websites seem to instanly redirect to their own websites and not staying on my local site.

Edge function exceeded 1mb

I got this error in vercel, using next.js v13.2, "Build Failed The Edge Function "index" size is 1.09 MB and your plan size limit is 1 MB." I guess that one of my pages are too large, but i can't figure out which one vercel is referring to since it's only telling me that index is too large which is a rather general name.

cache TRPC api query

Im building an api that returns the frequency of certain values from a mySQL database. These values dont get updated to often and would therefore like to cache the results somehow. Any tips on how i could do this best? Thought of simply using getStaticProps - but i need the data on a page that is server rendered so that option does not work.

Is it possible to encode tRPC data somehow?

I've built this webapp with t3 app and its mostly great - however i saw that all trpc data thats being sent from the backend can be found in the networks section of the chrome dev tools. Is there someway one can hide this - and at least make it a bit more tricky to get the data in raw form? There is no private data being sent - but access to the data in raw form is one of the largest moats of my product. Its taken a lot of time to assemble the data, and would be a shame if someone could just fetch it all using my site.

Pass different objects into same prop - TS error

Is it allowed to pass objects of different structure into the same prop, conditionally? Something like this


if (case = "teacher") {
    return (
        <div>
            <TeacherComponent person={teacher}/>
        </div>
    );
}
else if (case = "student") {
    return (
        <div>
            <StudentComponent person={student}/>
        </div>
    );
}

Note that teacher and student have different properties and do not have the same structure. Typescript is getting mad at me when doing this 🙂
