I'm a React Developer that uses Vim, and whilst I have reduced my .vimrc down a lot since I started playing with vim, I still use about 15 plugins such as Deoplete, tern, ale, fzf, a language pack (I'm always messing around learning new languages), and then a selection of Tim Pope addons.
At 120 lines, I consider my .vimrc quite light.. Although I'm not sure what others will think.
I used to shell into servers a lot and open vim to edit files, so I'm quite comfortable with a sparse configuration. But when I'm developing software, I want features, and these days I spend most of my time doing development. My current setup is I use Spacemacs for development work, but I use a very minimalist vim configuration for quick edits. This gives me the best of both worlds - very quick, responsive editor that I can use reliably and efficiently. And a good development experience that is easy on my fingers.
