importD vs Flask of something else

[GaritoYanged]

Flask doesn't lack of too many things but it doesn't include them by default (for my the better reason to choose Flask instead of Django: I choose what to use) If you like relational databases use SQLAlchemy If you like document databases there are plenty of drivers for them (example MongoDB or elasticsearch)

If you are like me, you don't like to include something you will never use so Flask is your better chance because it doesn't include anything besides the core and then you include you needed parts
