@mwittig Sorry, missed your comment. No, i didn’t look closer to the frontend. You are probably right. But since the frontend is also just a plugin, it would have to be migrated like the other plugins, too. But it could certainly be the plugin with the most effort.
Regarding time to work on this, i could maybe spend some days on this, but i can’t tell for sure.
But i guess you agree, if i say that we should start and see what happens. Maybe you want to create an “official” branch for the migration of pimatic core? This would be to solve the npm problems, and afterwards we can start and migrate one plugin after the other. I think it will be same tasks in most plugins, so we can create a “HOWTO” for plugin developers, after migrating the first plugins.
