TypeScript type for request object for route handlers

Mmeow

So far I've been writing my routes like:

export const router = t.router({
  helloWorld: t.procedure.query(async (req) => "Hello World"),
})

export const router = t.router({
  helloWorld: t.procedure.query(async (req) => "Hello World"),
})

What would be the type for req if I wanted to extract my handlers like so:

const handler = async (req:?) => "Hello World"

export const router = t.router({
  helloWorld: t.procedure.query(hander)
})

const handler = async (req:?) => "Hello World"

export const router = t.router({
  helloWorld: t.procedure.query(hander)
})

You'll have a really hard time extracting your handlers in some cases, but for this simple example you can just use some typescript magic

type QueryInputs = Parameters<typeof t.procedure.query>[0]

type QueryInputs = Parameters<typeof t.procedure.query>[0]
