Comparing tRPC and Server Actions for a SaaS Template: Seeking Insights and Advice

Hey everyone 👋, I've just posted a detailed comparison and discussion request on Reddit about tRPC vs. Server Actions in the context of a SaaS template using Next.js. My current setup uses tRPC with its experimental feature for server actions, and I'm considering a switch due to the community's lean towards server actions. Main points I'm pondering: - The abstraction and built-in features like caching in tRPC. - The need for custom implementation of these features in server actions. - The suitability of either approach for a unified API across web and mobile (React Native future plans). I'm at a crossroads and could really use your insights, especially if you've tackled similar challenges. Check out the full post and let's discuss: Reddit Post Looking forward to your thoughts and advice!

Auth through trpc procedures

Has Anyone Successfully Implemented Supabase Auth through tRPC Procedures in a Next.js App? Hello everyone 👋, I'm currently working on a Next.js project and trying to handle authentication using Supabase and tRPC. While I've been able to perform authentication directly via the Supabase client, I'm running into some issues when attempting to do the same through tRPC procedures. Specifically, sessions are not being added to cookies. Here's a snippet of my tRPC auth service routes:

export const authServiceRoutes = router({
  signup: publicProcedure
    .input(SignupInput)
    .mutation(async ({ ctx: { supabase }, input: { email, password } }) => {
      // Signup Logic
    }),
  login: publicProcedure
    .input(LoginInput)
    .mutation(async ({ ctx: { supabase }, input: { email, password } }) => {
      // Login Logic
    })
})

export const authServiceRoutes = router({
  signup: publicProcedure
    .input(SignupInput)
    .mutation(async ({ ctx: { supabase }, input: { email, password } }) => {
      // Signup Logic
    }),
  login: publicProcedure
    .input(LoginInput)
    .mutation(async ({ ctx: { supabase }, input: { email, password } }) => {
      // Login Logic
    })
})

When I perform authentication directly using Supabase like so:

await supabase.auth.signInWithPassword({ email, password });

await supabase.auth.signInWithPassword({ email, password });

Everything works as expected. However, using my tRPC procedures doesn't seem to set the session in the cookies. Has anyone faced a similar issue or successfully implemented this kind of setup? Any help would be much appreciated

how to handle error from Zod in trpc?

I would like to return error instead throwing it away so i could show user nice feedback i found https://zod.dev/?id=safeparse but i dont know how to implement it

  signup: authProcedure
    .input(SignupInput)
    .mutation(
      async ({
        ctx: { supabase },
        input: { email, password, repeatPassword },
      }) => {
        const user = await supabase.auth.getSession()
        console.log(user.data.session)
        console.log(email, password, repeatPassword)
      }
    ),


export const SignupInput = z
  .object({
    password: z.string().min(8),
    repeatPassword: z.string().min(8),
  })
  .refine(data => data.password === data.repeatPassword, {
    message: "Passwords don't match",
    path: ['repeatPassword'],
  })

  signup: authProcedure
    .input(SignupInput)
    .mutation(
      async ({
        ctx: { supabase },
        input: { email, password, repeatPassword },
      }) => {
        const user = await supabase.auth.getSession()
        console.log(user.data.session)
        console.log(email, password, repeatPassword)
      }
    ),


export const SignupInput = z
  .object({
    password: z.string().min(8),
    repeatPassword: z.string().min(8),

wrapper on useMutation (and another for useQuery) for creating multiple hooks

hi i want to create a wrapper for my router, basically I would like to achive somethink like that This is my appRouter:

export const appRouter = router({
  todoService: todoServiceRoutes,
})

export type AppRouter = typeof appRouter

export const appRouter = router({
  todoService: todoServiceRoutes,
})

export type AppRouter = typeof appRouter

This is my todoService router:

export const todoServiceRoutes = router({
  add: publicProcedure
    .input(apiTodoSchemaValidator.insertTodoSchema)
    .mutation(async ({ input: { title, description, isDone } }) => {
      return db
        .insert(todos)
        .values({
          title,
          description,
          isDone,
        })
        .returning({ insertedId: todos.id })
    }),
  getAll: publicProcedure.query(async () => {
    return db.select().from(todos).orderBy(desc(todos.id))
  })
})

export const todoServiceRoutes = router({
  add: publicProcedure
    .input(apiTodoSchemaValidator.insertTodoSchema)
    .mutation(async ({ input: { title, description, isDone } }) => {
      return db
        .insert(todos)
        .values({
          title,
          description,
          isDone,
        })
        .returning({ insertedId: todos.id })
    }),
  getAll: publicProcedure.query(async () => {
    return db.select().from(todos).orderBy(desc(todos.id))
  })
})

This is my wannabe custom hook:

export function useCustomMutation<T extends AppRouter>(
  config: ProcedureConfig<T>
) {
  const utils = api.useContext()

  const { service, action, optimisticUpdateEndpoint } = config

  return api[service][action].useMutation({
    onMutate: async input => {
      await utils[service][optimisticUpdateEndpoint].cancel()
      const updatedResults = utils[service][optimisticUpdateEndpoint].getData()

      const optimisticUpdate = updatedResults && [
        { ...input, id: updatedResults.length + 1 },
        ...updatedResults,
      ]

      utils[service][optimisticUpdateEndpoint].setData(
        undefined,
        optimisticUpdate
      )
    },
    onError: () => {
      utils[service][optimisticUpdateEndpoint].invalidate()
    },
    onSuccess: () => {
      utils[service][optimisticUpdateEndpoint].invalidate()
    },
  })
}

export function useCustomMutation<T extends AppRouter>(
  config: ProcedureConfig<T>
) {
  const utils = api.useContext()

  const { service, action, optimisticUpdateEndpoint } = config

  return api[service][action].useMutation({
    onMutate: async input => {
      await utils[service][optimisticUpdateEndpoint].cancel()
      const updatedResults = utils[service][optimisticUpdateEndpoint].getData()

      const optimisticUpdate = updatedResults && [
        { ...input, id: updatedResults.length + 1 },
        ...updatedResults,
      ]

      utils[service][optimisticUpdateEndpoint].setData(
        undefined,
        optimisticUpdate
      )
    },
    onError: () => {
      utils[service][optimisticUpdateEndpoint].invalidate()
    },
    onSuccess: () => {
      utils[service][optimisticUpdateEndpoint].invalidate()
    },
  })
}

and thats how I want to use it:

export function useAddTodo() {
  const { mutation, isLoading } = useCustomMutation({
    service: 'todoService',
    action: 'add',
    optimisticUpdateEndpoint: 'getAll',
  })

export function useAddTodo() {
  const { mutation, isLoading } = useCustomMutation({
    service: 'todoService',
    action: 'add',
    optimisticUpdateEndpoint: 'getAll',
  })

now how I can make it typesafe with intellisense (code completition, etc)
