hiposfer.rata.core
A reagent reactive wrapper around Datascript's transactor
Although this is a rewrite of mpdairy/posh library it is much more useful and simple. The problem with posh is that it tries to do too much. It target both datomic and datascript. Therefore it recreates the reagent/atom implementation internally.
This bring other problems with it:
-
all queries must be cached (but reagent is capable of doing that with reagent/track)
-
whenever the state changes, posh must figure out which query result should be updated (but reagent is capable of doing that by diffing the result of the queries)
-
only the currently viewable components's queries should be executed (but reagent already does that since all inactive reagent/track are removed automatically)
-
all the problems above also make posh a big library with hundreds of lines (reagent.tx has barely 50 even with all datascript functionality !!)

listen!cljs
(listen! conn)registers a listener for the connection transactions. Returns the conn object itself with the added listener and state holder
Subsequent usages of conn in q! and pull! will return reactive atoms that will update their value whenever the Datascript value changes
