Re: [ClojureScript] Subscriptions tracking in Re-frame
I think you may have hit on what I need to run - the level 3 subscriptions. I am reading from a database (datascript in this case) on the device and I want to minimize the number of queries I am making because I expect the database to grow in size. I have no problem with it being re-run if it is data residing in app-db, but it is this db access that I want to keep to the minimum. Thank you for this link - I think I will REREAD my re-frame subscriptions literature and understand that a little better... Cheers @basket!!!

Re: [ClojureScript] Subscriptions tracking in Re-frame
I have seen re-frame-10x indeed..and it is a fantastic tool. And maybe that is where the answer lies as @danielcompton said on another issue. However, I guess what I am trying to debug is how to tell definitively, which specific de-ref of my reaction triggered a particular subscription to be rerun. If this information is not currently something immediately available, I did have other questions such as: - Does re-frame cache the results of a subscription run ? if so, where is the documentation or even informal information about that ? - can I identify which specific deref causes a rerun ? While I can see the effects of running subscriptions and events in 10x, I am trying to debug the specific areas in code that triggered their running DOes this help ?

[ClojureScript] Subscriptions tracking in Re-frame
Hi I am using re-frame with expo/react native and my components are deeply nested .I create a pass into this nested structure a new atom I construct FROM the atom of a subscription. I pass that in since reactions cannot be edited and I want this structure to be edited. However, the nested structure contains a component that displays a modal. Whenever I open the modal and close the modal control, it forces a re-fetch of the subscription data. The questions: 1. Why would the subscription be called again if I did not pass into the nested structure the original reaction ? 2. Should I worry about this retrigger even if the data has not changed ? I see it pulling the same stuff but maybe it is just passing back results that are cached ? Are they cached ? 3. Is there a way in re-frame to definitively identify which deref of the reaction/atom causes the subscription to be re-run ? thanks for any help on this. -- Note that posts from new members are moderated - please be patient with your first post. --- You received this message because you are subscribed to the Google Groups "ClojureScript" group.
