code chage to make middlewaresFile a middlewaresModule (optionally) instead

[earonesty]

having it be a js file means various bundlers and optimizers can't work well

shouldn't be hard to allow the user to pass in an already imported middlewaresModule, unless you can think of a better way to deal with that

I don't have much capacity for it right now, maybe you can do it or perhaps @motigra / @yotamgever can assign someone interested.
