Setting up Vim for JS Development

I switched to Vim about 2 years ago and haven't looked back since. At first, it was hard. However, once you get a hang of it and start to work on it, you'll realize that it's the best thing ever. There are plenty of articles on this subject, but many of those are too verbose for my liking.

To keep things short, I will only list out the steps, .vimrc file, and necessary comments for setting up Vim successfully.

Setting Up Vim

Plugin Manager for Vim

  • Vundle
  1. $ git clone https://github.com/VundleVim/Vundle.vim.git ~/.vim/bundle/Vundle.vim
  2. Set up neocomplete (a code completion tool you need to run the following) and Ack (search)

For Mac

brew install vim --with-lua

For Ubuntu

Refer to: https://github.com/Shougo/neocomplete.vim

Install Ack: https://beyondgrep.com/install/

(Needed for file searching)

  1. Install powerline fonts : https://github.com/powerline/fonts

  2. Install the awesome solarized theme : http://ethanschoonover.com/solarized

Make sure you set up the font in terminal preferences to a powerline font.


.vimrc

Update the.vimrc file for plugins setup. (This is the minimal basic setup code, if you are using Java, Python, or any other language, you can skip the rest of the article)
