Wrong type for ServerMiddleware

Describe the bug ServerMiddleware is defined as an alias of RequestHandler from express. However, if you try to use for example the function req.send, which is available according to the types, it will fail.

To Reproduce

1. Create this function as a serverMiddleware:

    (req, res) => {
      res.send('OK')
    }

1. Make a request to the server and observe that you get the error “res.send is not a function”.

Expected behavior The types should not include functions which don’t exist in runtime. I’m not sure what the correct type is though, maybe RequestListener from http.

Additional context Versions: nuxt: 2.10.2 @nuxt/typescript-build: 0.3.3 @nuxt/typescript-runtime: 0.2.3

The whole function is NextHandleFunction

Yeah right, I think it should be NextHandleFunction from connect instead of RequestHandler from express for sure !
