Setting up (Neo)vim for React development

It’s been 8 months since I have been using (neo)vim as my primary text editor. Initially it was incredibly tough to adopt and use it in work. Well that would be another story to tell.

Back then I was working mostly in backend using CoffeeScript (I know 🙈). VS Code had a little support for CoffeeScript so I didn’t had any problems using vim full time.

But things changed drastically when I moved into UI development this year. I had to spend hours reading blogs, threads on reddit to create at least a workable setup for a hassle-less React enviornment. Here I am sharing my vim setup for JS/React development.

Note: I am using Vundle for plugin management.

Syntax Highlighting

Out of the box vim/nvim supports syntax highlighting for major programming languages.

  ls /usr/share/vim/vim80/syntax/

vim-jsx is by far the best jsx plugin for vim. vim-javascript provides better syntax highlighting and code folding support compared to the default one.

  Plugin 'mxw/vim-jsx'
  Plugin 'pangloss/vim-javascript'

But It is yet to add jsx to its inventory. Also there are some javascript specific plugins that makes syntax highlighting much better.

Linters and Formatters

Well everyone has a love hate relationship with linters. Nobody likes those annoying red lines on the editor the moment they add a newline.

But with vim You are in luck. ALE is a nice plugin that asynchronously checks for syntatical errors in the code. It supports mnay language specific linters and formatters. ALE also lets people configure the signs for errors and warnings.

  Plugin 'w0rp/ale'

For JS/React development to add eslint as a linter and prettier I added this to my vimrc

  let g:ale_linters = {
    \ 'javascript': ['eslint'],
    \}

  let g:ale_fixers = {
    \ 'javascript': ['prettier', 'eslint']
    \ }

I also mapped leader+d as my ale fixer and configured to format each time I save the file.

  let g:ale_fix_on_save = 1
  nmap <leader>d <Plug>(ale_fix)

Autocompletion

Auto completion in vim is not as good as any modern IDE but Deoplete is worth taking a look.

Check the repo for installation guides.

Commenting

Though this is not specific to any particular language I would like to discuss an excellent plugin which is pretty good at commenting and uncommenting code. NerdCommenter definitely going to save you a few additional key-presses a day and being a vimmer is all about that.

  Plugin 'scrooloose/nerdcommenter'

Conclusion

With vim it’s hard to find an universal config that suits everyone. It’s always solving one problem at a time that led me here. This is definitely not a full fledge solution to this but it seems to work pretty well for me. So if you have any suggestion feel free to ping me on Twitter .
