I have never felt the need to write swagger by hand, despite publishing a few API's in it. I always generate them directly from the domain code/function arguments. It might be a benefit of statically typed languages though. I have no idea how you would automatically generate swagger from Javascript, without adding so much annotations that they become a poor man's types.
