How do I implement API key authorization along with JWT authorization in tRPC?

Hello, I want to make some routes protected and to be accessed by either JWT auth or by API keys auth. So I check both auth methods in the same context. To make things clear i will just share the code of my context:

export async function createContext({ req, res }: CreateFastifyContextOptions) {
  async function getUser() {
    try {
      const apiKey = req.headers['x-api-key']

      if (apiKey) {
        if (typeof apiKey !== 'string') {
          throw new TRPCError({ code: 'BAD_REQUEST', message: 'Invalid API key' })
        }
        const isValid = await validateApiKey(apiKey)
        return {
          user: null,
          isAuthorized: isValid
        }
      } else {
        await req.jwtVerify()
        const em = orm.em.fork()
        const user = await em.findOne(User, { _id: new ObjectId(req.user.id) })

        if (!user) return null
        const u = wrap(user).toPOJO()
        return {
          user: u,
          isAuthorized: true
        }
      }
    } catch (err) {
      console.log('Error getting user from header or cookie', err)
      return null
    }
  }

  const user = await getUser()

  return {
    req,
    res,
    user
  }
}

export async function createContext({ req, res }: CreateFastifyContextOptions) {
  async function getUser() {
    try {
      const apiKey = req.headers['x-api-key']

      if (apiKey) {
        if (typeof apiKey !== 'string') {
          throw new TRPCError({ code: 'BAD_REQUEST', message: 'Invalid API key' })
        }
        const isValid = await validateApiKey(apiKey)
        return {
          user: null,
          isAuthorized: isValid
        }
      } else {
        await req.jwtVerify()
        const em = orm.em.fork()
        const user = await em.findOne(User, { _id: new ObjectId(req.user.id) })

        if (!user) return null
        const u = wrap(user).toPOJO()
        return {
          user: u,
          isAuthorized: true
        }
      }
    } catch (err) {
      console.log('Error getting user from header or cookie', err)
      return null
    }
  }

  const user = await getUser()

  return {
    req,
    res,
    user
  }
}

I am using Fastify.js. What do you think of this approach? Thanks.

Is to possible to update the trpc client url?

Hello, I have create my trpc client this way:

trpcClientZS = trpcReactZS.createClient({
    links: [
      httpBatchLink({
        url: `http://192.168.1.2:3000/trpc`,
        fetch(url, options) {
          return fetch(url, {
            ...options,
            credentials: 'include'
          })
        },
      })
    ],
    transformer: SuperJSON
  })

trpcClientZS = trpcReactZS.createClient({
    links: [
      httpBatchLink({
        url: `http://192.168.1.2:3000/trpc`,
        fetch(url, options) {
          return fetch(url, {
            ...options,
            credentials: 'include'
          })
        },
      })
    ],
    transformer: SuperJSON
  })

Is there a way i can change the url in the httpBatchLink when the app is running? I tried to create and override the old instance but it didn't work. Thanks.

How do I set header value from localStorage or Zustand in tRPC and React?

Hello, This is my tRPC client in my App.tsx:

function App(): JSX.Element {
  const { token } = useAuthStore()
  const [trpcClient] = useState(() =>
    trpcReact.createClient({
      links: [
        httpBatchLink({
          url: 'http://192.168.1.17:3000/trpc',
          fetch(url, options) {
            return fetch(url, {
              ...options,
              credentials: 'include'
            })
          },
          headers: () => {
            return {
              Authorization: `Bearer ${token || ''}`
            }
          }
        })
      ],
      transformer: SuperJSON
    })
  )

function App(): JSX.Element {
  const { token } = useAuthStore()
  const [trpcClient] = useState(() =>
    trpcReact.createClient({
      links: [
        httpBatchLink({
          url: 'http://192.168.1.17:3000/trpc',
          fetch(url, options) {
            return fetch(url, {
              ...options,
              credentials: 'include'
            })
          },
          headers: () => {
            return {
              Authorization: `Bearer ${token || ''}`
            }
          }
        })
      ],
      transformer: SuperJSON
    })
  )

The problem is if the jwt token changes, it doesn't get changed in the trpcClient unless I do something like this but I don't like it:

useEffect(() => {
    if (token)
      setTRPCClientZS(
        trpcReactZS.createClient({
          links: [
            httpBatchLink({
              url: 'http://192.168.1.17:3000/trpc',
              fetch(url, options) {
                return fetch(url, {
                  ...options,
                  credentials: 'include'
                })
              },
              headers: {
                Authorization: `Bearer ${token}`
              }
            })
          ],
          transformer: SuperJSON
        })
      )
  }, [token])

useEffect(() => {
    if (token)
      setTRPCClientZS(
        trpcReactZS.createClient({
          links: [
            httpBatchLink({
              url: 'http://192.168.1.17:3000/trpc',
              fetch(url, options) {
                return fetch(url, {
                  ...options,
                  credentials: 'include'
                })
              },
              headers: {
                Authorization: `Bearer ${token}`
              }
            })
          ],
          transformer: SuperJSON
        })
      )
  }, [token])

What is the best way to set jwt to trpc client?

What do you guys think about the approach of importing/exporting tRPC types to be used in separate B

Hello, I was looking for a way to share tRPC API between multiple electron apps, I thought first about using a Nx monorepo but it turned out it's almost impossible to make it work with electron app that use electron-vite. After more research I found this repo: https://github.com/mkosir/trpc-api-boilerplate What I understood from this approach is you export the types of the tRPC server with all db types from the backend repo and you import them in any other -frontend- repo using GitHub API (Octokit). Is this approach common in general programming environments and what do you think about it? Thanks.

useMutation() runs 3 times

Hello, I have this weird problem that all my mutations across the app runs 3 times I don't know why. This is my API in the backend:

import { initTRPC } from '@trpc/server'
import superjson from 'superjson'

import routers from './routers'
import { brandFormSchema } from './zod-schemas'

const t = initTRPC.create({ isServer: true, transformer: superjson })

export const router = t.router({
  ...routers
})

export type AppRouter = typeof router

import { initTRPC } from '@trpc/server'
import superjson from 'superjson'

import routers from './routers'
import { brandFormSchema } from './zod-schemas'

const t = initTRPC.create({ isServer: true, transformer: superjson })

export const router = t.router({
  ...routers
})

export type AppRouter = typeof router

And this is how I use them in the client:

import { notifications } from '@mantine/notifications'
import { trpcReact } from '@renderer/util/trpc'

import BrandForm from './brand-form'

type Props = {
  onCreated: () => void
  onCancel: () => void
}

function CreateBrand({ onCreated, onCancel }: Props): JSX.Element {
  const utils = trpcReact.useUtils()

  const { mutate, isLoading } = trpcReact.brand.create.useMutation({
    onSuccess: (): void => {
      utils.brand.all.invalidate()
      notifications.show({
        message: 'Added brand successfully!',
        color: 'green'
      })
    },
    onError: (error): void => {
      notifications.show({
        message: 'Brand not added!' + error,
        color: 'red'
      })
    }
  })

  return (
    <BrandForm
      loading={isLoading}
      submitHandler={(values): void => {
        mutate(values)
        onCreated()
      }}
      cancelHandler={(): void => {
        onCancel()
      }}
    />
  )
}

export default CreateBrand

import { notifications } from '@mantine/notifications'
import { trpcReact } from '@renderer/util/trpc'

import BrandForm from './brand-form'

type Props = {
  onCreated: () => void
  onCancel: () => void
}

function CreateBrand({ onCreated, onCancel }: Props): JSX.Element {
  const utils = trpcReact.useUtils()

  const { mutate, isLoading } = trpcReact.brand.create.useMutation({
    onSuccess: (): void => {
      utils.brand.all.invalidate()
      notifications.show({
        message: 'Added brand successfully!',
        color: 'green'
      })
    },
    onError: (error): void => {
      notifications.show({
        message: 'Brand not added!' + error,
        color: 'red'
      })
    }
  })

  return (
    <BrandForm
      loading={isLoading}
      submitHandler={(values): void => {
        mutate(values)
        onCreated()
      }}
      cancelHandler={(): void => {
        onCancel()
      }}
    />
  )
}

export default CreateBrand

I am sure that the call from the client doesn't run 3 times. I checked it with console.log. I would be grateful if anyone helped. THanks.
