Would it be fair to say that Flask is roughly equivalent to Sinatra, only in Python instead of Ruby?
I’ve only done a tiny bit of playing with Sinatra, but I’d say that it’s an apt comparison. From my vague recollection of Sinatra I’d say it’s slightly more micro than flask.
What do you mean? What’s there so heavy about Flask?
Except that, while in the Ruby world, Rails is the number one (only?) choice, the Python world is more fragmented. I won’t say if this is a good or bad thing. I personally prefer Flask.
I bought the book when it came out. It is more useful for people who already know some Flask, as it teaches best practices (a bit like 2 scoops of Django).
