Possible to call a server function within an api route?
I can't get around this error: createServerFn must be called with a function that is marked with the 'use server' pragma. Are you using the @tanstack/start-vite-plugin

please provide a minimal complete example

// app/functions/getServerTime.ts
import { createServerFn } from '@tanstack/start'
export const getServerTime = createServerFn().handler(async () => {
// Wait for 1 second
await new Promise((resolve) => setTimeout(resolve, 1000))
// Return the current time
return new Date().toISOString()
})
// app/routes/api/users.ts
import { json } from '@tanstack/start'
import { createAPIFileRoute } from '@tanstack/start/api'
import { getServerTime } from '../../functions/getServerTime'
export const APIRoute = createAPIFileRoute('/api/users')({
GET: async ({ request }) => {
const time = await getServerTime();
return json({ message: 'Hello "/api/users"!', time });
},
})

ah I think you can't call a server function from an API route
that sounds strange when I type it out
@Sean Cassiere am I right though?

I don't think we've got the functionality for it.
Since both are separated into different bundles and I don't think we've gone about mapping how the request for the client-runtime works when the Vinxi router is for API routes.

Makes sense. I was exploring exposing the functionality of RPC functions through the API, but not sure if practically that makes sense. Maybe clarification in the docs, though:
https://tanstack.com/router/latest/docs/framework/react/start/server-functions
They can be called from anywhere in your application, including loaders, hooks, components, etc.
Server Functions | TanStack Router React Docs
What are Server Functions? Server functions allow you to specify logic that can be invoked anywhere (even the client), but run only on the server. In fact, they are not so different from an API route,...

can you create a PR for the docs?

Yes I can do that this evening.

When you do so, could you please use a Github Warning?
