Default input typing for routes to use void not unknown #1135
Description
Describe the feature
Problem
Currently, when defining procedures without an explicit .input() call, the default input schema is Schema<unknown, unknown>, which causes TypeScript errors when calling procedures that don't require input.
Example:
// playgrounds/next/src/routers/ping.ts
export const ping = pub.output(PingSchema).handler(() => 'pong')
export const pingVoid = pub.input(PingVoidSchema).handler(() => 'pong')// playgrounds/next/src/app/orpc-mutation.tsx
const { mutate: testMutate } = useMutation(orpc.ping.run.mutationOptions())
const { mutate: testVoidMutate } = useMutation(orpc.ping.runVoid.mutationOptions())
useCallback(() => {
testMutate() // ❌ Type error! Must provide argument even though input is unused
testMutate(undefined) // ✅ Works but awkward
testVoidMutate() // ✅ Works because explicit z.void() was specified
}, [testMutate, testVoidMutate])This forces developers to either:
- Always pass
undefinedas an argument (testMutate(undefined)), or - Explicitly add
.input(z.void())to every procedure without input
Both approaches add unnecessary boilerplate and hurt developer experience.
Proposed Solution
Change the default input schema from Schema<unknown, unknown> to Schema<void, void> for both os and oc builders.
Before:
// Must explicitly specify z.void() or risk type errors
export const ping = pub.output(PingSchema).handler(() => 'pong')
export const pingVoid = pub.input(z.void()).handler(() => 'pong')
// Usage requires explicit undefined or no arguments depending on schema
testMutate(undefined) // Required for ping
testVoidMutate() // Works for pingVoidAfter (with this feature):
// Both work the same way - z.void() is implicit by default
export const ping = pub.output(PingSchema).handler(() => 'pong')
export const pingVoid = pub.output(PingSchema).handler(() => 'pong')
// Usage is consistent - no arguments needed
testMutate() // ✅ Works!
testVoidMutate() // ✅ Works!Additional information
