Today, I came across AdonisJS. I was surprised to learn it's been around since 2015, but I had never heard of it.
Even though it's a JS framework, the focus is more on the backend. You can use any frontend library. It has official support for InertiaJS.
I like that it's strongly opinionated and puts focus on developer experience.
I went through the entire documentation. It's hard to explain, but it has taste—something about it just feels well-thought-out and put together with care.
Funny how reading good docs can trick you into redesigning your blog font at midnight. Anyway, Instrument Sans it is.
