I have been working my way through how works and implementing routing similar to compassus, however I am struggling with what happens after I change the route. Basically, I use first approach in this post -> , where my Root component contains queries for all routes. Initial dispatch works well, my :remote is requested and response displayed. However, after change-route! remote is not requested anymore. I assume it’s because change-route! didn’t actually touch buried keys inside. How would I force reconciler to execute query of the chosen corresponding route?

I assumed just returning {:remote true} from read would be enough to force data fetching (without :value). Is it correct?

If anyone is interested, Ethan and I beefed up the documented story of how Untangled implements Om Next networking and avoids having you write a parser. Even if you don’t want to use Untangled, this covers some of the core realizations and decisions we think make using Om Next much easier. It also gives you a good idea of what the trade-offs are:!/untangled_tutorial.H_Server_Interactions

thanks for that, reading this page was very enlightening

I need a library for manage routes management. I’ve seen Secretary and Bidi. What do you think is better?

In, what’s the difference between query and query expression?

Hmm, any hints why after re-reading keys :ast doesn’t have :query anymore? (om/transact! reconciler ‘[:board/list]) [..logs] ast {:type :prop, :dispatch-key :board/list, :key [:board/list]}

Essentially sends empty route to the back-end.. Can’t quite figure it out.

As opposed to initial rendering, (say on page reload) ast {:type :join, :dispatch-key :board/list, :key :board/list, :query [:db/id :board/name :board/description], :component boards-io.components/BoardItem, :children [{:type :prop, :dispatch-key :db/id, :key :db/id} {:type :prop, :dispatch-key :board/name, :key :board/name} {:type :prop, :dispatch-key :board/description, :key :board/description}]}
