I propose the following tutorial
It is about Caqti and ppx_rapper use. The tutorial also uses the
Lwt_result monad and its
(let*) binding operator. This avoid any explicit error handling.
I hope this will be interesting, and will be glad to get some advice to improve this first copy.
Perhaps I should add a section about processing a
list of queries (ex: a query returns a list of item and we want to execute a new query for each row)
