nextjs all pages are dynamic

I am using create t3 app with app router created like ~3/4 months ago. This implementation makes all pages that use api exported either from react.tsx or from server.ts dynamic even if I am not using headers in a current procedure. What can I do to make pages dynamic only if the current procedure uses next/headers

React hook form context zod

Why is the error in Input not showing after submitting form? It looks like context breaks a subscription somehow. Any help? 🙂 https://codesandbox.io/s/react-hook-form-re-validate-issue-7y7ssx?file=/src/App.tsx

Typesafe query keys

Hey I am curious how do you guys manage your query keys and keep track of them. In a complex application managing them and keeping track of which one to invalidate seems hard for me. Is there an option to make them somehow typesafe? I haven't found any good articles on this topic :/

Typescript array typing

Hey I was wondering why typescript doesn't indicate that the name here is possibly undefined when the arr is empty?

type T = { name: string }[];

const arr: T = [];

const name = arr[0].name; // no ts error but it throws Cannot read properties of undefined

type T = { name: string }[];

const arr: T = [];

const name = arr[0].name; // no ts error but it throws Cannot read properties of undefined

Handling prisma errors

Hey, quick question. Let's suppose that in my db I have model User with few unique fields: name, surname, email Should I validate manually that those fields are unique and throw an error if not or should I just let prisma do it? I guess that the 2nd solution is better. How do I map prisma errors to show more human friendly messages than this:

{
    "statusCode": 500,
    "code": "P2002",
    "error": "Internal Server Error",
    "message": "\nInvalid `prisma.user.create()` invocation in\nC:\\Users\\-.-\\Desktop\\icerty\\apps\\server\\modules\\users\\users.routes.ts:78:40\n\n 78 const offer = await prisma.user.create(\nUnique constraint failed on the fields: (`name`)"
}

{
    "statusCode": 500,
    "code": "P2002",
    "error": "Internal Server Error",
    "message": "\nInvalid `prisma.user.create()` invocation in\nC:\\Users\\-.-\\Desktop\\icerty\\apps\\server\\modules\\users\\users.routes.ts:78:40\n\n 78 const offer = await prisma.user.create(\nUnique constraint failed on the fields: (`name`)"
}

Zod like parser in typebox

Hey, I have a schemas made using @sinclair/typebox and I am looking for a similar option to .parse method provided by zod that throws an error. I see that @sinclair/typebox offers .Check method but it does not throw an error. Also there is an .Errors method that returns me an array of validation error but still I'd have to throw it manually. Am I missing something there?

Server vs client components

I am building an app that lets users create an offers just like on amazon. Is it a better idea to fetch those offers on client side or server side? Or it depends on the scale of an application?

Prevent possibly undefined user with useQuery

I have a hook useUser that looks basically like this

return useQuery(// fetch user)

return useQuery(// fetch user)

Lets imagine that its used in a Layout so when the user is loading the whole app is just a loading spinner. Now I want to get the user inside a component nested in Layout Using useUser hook makes no sense here because its return is always User | undefined as typescript doesn't know the user is loaded somewhere higher. How do I solve this problem? Checking

if(!user) return

if(!user) return

Doesn't seem good because the user is always here if the component rendered.
