I’m using figwheel with re-frame, which I assume is fairly idiomatic

I would like to prevent the db from being reset on code changes …. is there a standard pattern for achieving this?

It's been a good year or two since I've touched re-frame, but I don't recall the db ever changing when I saved code and had figwheel update it. I don't think I had to do anything special to opt in to that behavior

@raymcdermott just make sure you use defonce for the db

@isak yes I have tried that but am still getting some value replaced

maybe I have misspoken … cos now I am debugging some more it seems like its just external JS objects

hmm, maybe there is a dispatch being triggered in your code somewhere that's not behind a defonce?

I am using code-mirror and it is being lost on reload

ah, right for those you need special handling to get it to work - see the handling stateful js components doc

ah OK I haven’t came across that one

I’ll look it up - thanks

Ok, I’m not following that pattern … awesome - thanks @isak

and @bfay I agree with your general advice - so thanks, I should have been clearer

for CM I needed to add a noop fn for component-did-update so a small variation on that theme
