@elik-ru thanks for the PR 🙌 I will review and test on the weekend

Nice PR. Tested at my end, the only thing that didnt work out was the default :css mode, my setup is jsbundling + cssbundling + talwindcss.

It fails silently here because my stylesheet tag do not contain a stylesheet data attribute, as your code is expecting. My link is:

<link rel="stylesheet" href="/assets/application-{{big-hash-here}}.css" data-turbo-track="reload">

I could fix it adding the data attribute manually, like this:

# application.html.erb
<%= stylesheet_link_tag "application", "data-turbo-track": "reload", "data-stylesheet": "application.css" %>

Is this expected?

@LEstradioto Thanks for your feedback!
Yes, this is kinda expected, because actual filename differs form digested url, and digested url changes when file changes, there is no easy way to match actual filename and corresponding <script> tag. So i simply added a data attribute. May be there is a way to patch stylesheet_link_tag and make it add data attribute automatically, but given that we have multiple options (sprockets of various versions, Propshaft etc), i think it does not worth it. It's easy to add attribute manually, we just need to document it properly.

Hi @kirillplatonov! How is it going? Can i help you in somehow to make it easier to review?

@elik-ru could you please extract reloading on error pages into separate PR? It would be easier to review and merge this way

@kirillplatonov There 2 commits for 2 features, but seems some improvements leaked from one to the other.
Ok, i'll prepare 2 separate PRs
