Angular components and directives autocomplete in vim

It's not perfect but Deoplete is probably as good as it gets. In my use case it's pretty good at picking up keywords you've used and autocompleting those. It works with html. Requires either Vim8 or Neovim. I personally can't recommend Neovim enough.
