Echo JS 0.11.0

I'm front-end guy and I'm missing the problem with that article. Arguments in article seem reasonable, what's wrong then? Does he generalise one example of bad middleware code to all middleware or is that code even okay and he misses on the idea of middleware?

My post is probably not clear enough. The TL;DR is use pure functions composition not middlewares.

I am currently writing another post were i try to explain my point of view in a more in depth manner, hope it will help clarifying. You input it welcome https://github.com/nfroidure/blog/blob/4b6bfdccea8ad404dcc2bc116fa609f220388a5c/contents/pages/en/blog/http_rest_apis_with_nodejs.html
