@joomdonation It needs to fix javascript-cs, see https://ci.joomla.org/joomla/joomla-cms/42929/1/21 .

@wilsonge As of right now, all the errors are fixed and I would say that it works in the same way with what we are having on 3.10.0. You can review the code and get it merged (I made basic test by installing older version of Akeeba Backup and JCE editor for testing)

However, there are still some problems:

• The layout of the page does not look good. We should have someone with frentend/design skill to take a look at it and sovle it
• During the code review, I can see a potential issue (comes from the original code, before we do this conversion to convert to vanilla js). See https://github.com/joomla/joomla-cms/blob/3.10-dev/media/com_joomlaupdate/js/default.js#L292

Basically, from what I understand, the loop over all the none core plugins and if that plugin belong to an extension, remove it from the array. But that could cause all plugins load being checked (causes by the removal mentioned). Maybe you can ask the developer who worked on the feature to take a look at it.

However, there are still some problems:

George had asked me to fix this after the BS js PR but I never made a PR because my solution (SPA basically)was touching the restore.php and that wasn't a discussion I wanted myself involved. This is (I think) the repo: https://github.com/joomla/joomla-cms/compare/4.0-dev...dgrammatiko:4.0-dev_joomlaUpdate?expand=1

At the very least check the changes in the controller and the way I pass data from PHP to JS. The current state is god awful...

@dgrammatiko I haven't spent time to read the whole code to understand the process, so I could not comment on your solution right now. However, if you make a PR, I would be happy to review and test it. The current code is not looking good, I agree.

Starting to look better. Thanks for fixing my mess trying to port this!

This is clearly an improvement merging this now
