[ClojureScript] Re: (failed) Attempts to inject cljs repl into 3rd party webpage

[John Newman]

I made a thing for that here https://www.chrepl.app/

I haven't made it work with shadow-cljs yet, but that'd be an interesting 
option.

V/r

Re: [ClojureScript] Subscriptions tracking in Re-frame

[Deuseks]

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!!!

 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.

[ClojureScript] Re: (failed) Attempts to inject cljs repl into 3rd party webpage

[Thomas Heller]

You cannot really inject a shadow-cljs dev build into any arbitrary page. 
It is not designed for that and will potentially conflict with the page 
itself in bad ways.

You can set :devtools {:devtools-url "https://your.host:23456"} to 
overwrite where the socket is trying to connect to. The Browser console 
will tell if you that connect fails.

DOMContentLoaded is not used by the CLJS build, not sure why you are asking 
about it. If you are trying to register an event handler for it you are 
likely just registering it too late when it has already fired.
