Basically I'm just wondering if grass is greener on the other side.

Don't get me wrong, I really like FE development and I've been successful in creating a nice career out of it for myself, becoming specialist in certain areas - I'm working on what is now I guess considered "modern" web apps. That means more or less creating React SPAs and figuring out the whole tech stack (webpack etc).

I do have experience with BE as well but last time I did any professional work was 4 years ago, I used to be Ruby on Rails developer and I liked that as well. I can also do some NodeJS development and work with databases. So I think I have general idea of both sides, just not very up-to-date on current backend tech.

I am asking because I seem to notice micro-trend where some people are actually advocating for moving back to monolith architecture and manage user state, including FE all at one place (server), Phoenix's LiveView comes to mind. I have not tried these new web-socket approaches yet. I was thinking maybe having a look at that and if the trend actually becomes norm, I'd like to have the skill set.

I know BE has become more complex as well with introduction of Kubernetes and other technologies (or more simple? IDK).

What is your take on this?
