Why would a backend developer care about front end stuff like jade/haml? 
Just don't use those parts ;)

It depends on which database you need to connect to. For PostgreSQL 
there's ddb [1] and for MySQL there's mysql-native [2].

I don't know about mysql-native, but for ddb you can use the PGCommand 
class and the executeQuery or executeRow to execute the query and 
specify the struct that should be returned.

vibe.d has built-in support for serialization [3].
