Hi all, We are in a process of migrating our legacy Angular 1.x SPA app to Elm where we still have some parts of the app in Angular and still using its router plus we have couple of Elm apps which are embedded to DOM nodes when route is changed (to e.g. #/moduleX ). What I noticed is that if I nav…

I would also like to know if there is a solution in 0.19 In 0.18 the best we could do is stop the subscriptions…

Thanks Brian! That helped a lot.

It’s still the same for 0.19. I’ve prepared a package to automate this work but have not published yet. It seems it’s not possible to publish modules with ports for 0.19. Hope I can find time to publish the package soon.

Or am I misinterpreting your question? Side note: This language is called ‘Elm’ (as in th…

The issue is that you’re still receiving URL updates even if subscriptions = Sub.none because Navigation.programWithFlags subscribes to it (not the application code itself). Thanks for the Side note :slight_smile:

There have been some previous discussions here about that. Search for “unmount”. This one has a suggested technique. I think it’s probably 0.18, haven’t re-read it in detail to check. But may give you ideas.
