There are a ton of past threads on this, many valuable, and some huge. You can find them by searching [Ask HN web] (or stack or framework, etc.) in the search box at the bottom. Here are some decent-sized ones going back to 2016, but there are many more. I figure if something is recommended a few years ago and also recently, it's probably good, stable, and well-documented.
