reg-subclj/s
(reg-sub query-id & args)Register a given handler function for a given query id.
There's 3 ways this function can be called
-
(reg-sub :test-sub (fn [db [_]] db)) The value in app-db is passed to the computation function as the 1st argument.
-
(reg-sub :a-b-sub (fn [q-vec d-vec] [(subs/subscribe [:a-sub]) (subs/subscribe [:b-sub])]) (fn [[a b] [_]] {:a a :b b}))
Two functions provided. The 2nd is computation fucntion, as before. The 1st
is returns what input signals should be provided to the computation. The
input signals function is called with two arguments: the query vector
and the dynamic vector. The return value can be singleton reaction or
a sequence of reactions.
- (reg-sub
:a-b-sub
:<- [:a-sub]
:<- [:b-sub]
(fn [[a b] [_]] {:a a :b b}))```
This 3rd variation is just syntactic sugar for the 2nd. Pairs are supplied instead
of an
input signalsfunctions.:<-is supplied followed by the subscription vector.

Two functions provided. The 2nd is computation fucntion, as before. The 1st
is returns what `input signals` should be provided to the computation. The
`input signals` function is called with two arguments: the query vector
and the dynamic vector. The return value can be singleton reaction or
a sequence of reactions.
