I found this to be true when building a SPA. On rails I am already told the best place to put things but on the JS side its just "do whatever you want" so I try something and find out later that it wasn't a great way to do things so I am just wasting my time working out the best way to organize a project. I also have to deal with index files that just import every single component for the frontend when on rails this kind of stuff is auto generated.
