Typing a factory function for createFileRoute

Hello everyone, I am trying to create a factory function that returns a createFileRoute with some options predefined, but I am not able to type it correctly with all the generics. Here is an example what I am trying to accomplish:

function customCreateFileRoute(path) {
  return (options) => {
    return createFileRoute(path)({
      ...options,
      staticData: {
        title: 'Test',
        ...options.staticData,
      },
    })
  }
}

function customCreateFileRoute(path) {
  return (options) => {
    return createFileRoute(path)({
      ...options,
      staticData: {
        title: 'Test',
        ...options.staticData,
      },
    })
  }
}

Can someone help me with the correct types? Thanks in advance.

it won't work at compile time with automatic code splitting though we currently don't support abstractions on top of createFileRoute

So I guess the best alternative way to accomplish this is to pass all the predefined options to each createFileRoute separately?

const defaultStaticData = {
  title: 'Test',
} as const

createFileRoute('/test')({
  staticData: {
    ...defaultStaticData
  },
})

const defaultStaticData = {
  title: 'Test',
} as const

createFileRoute('/test')({
  staticData: {
    ...defaultStaticData
  },
})

yes

And are there any plans of supporting this kind of abstractions? I have quite a lot of routes with the same options, so it would be much better to use that way

it's in my wishlist but quite involved due to the static analysis the compiler needs to do for this not a high priority right now

ok, looking forward for that. thank you
