Syntastic Checker for React JSX files

This is a simple wrapper that:

• Tries to compile as JSX
• Checks if the JSX compiler throws errors, and sends them to Syntastic if so
• Otherwise, passes JS to JSHint and outputs any errors found there

This gives you the power of syntax checking in Vim, without the annoyance of "unexpected regular expression". Awesome.

Usage

npm install -g syntastic-react

If you don't have jshint or react-tools, install those too:

npm install -g jshint
npm install -g react-tools

Add these lines to your vimrc:

let g:syntastic_javascript_checkers = ['jsxhint']
let g:syntastic_javascript_jsxhint_exec = 'jsx-jshint-wrapper'

And, of course, install Syntastic.

Why? What about JSXHint?

JSXHint is being sunsetted and doesn't handle React errors correctly. This code is a simple wrapper that brings the best of both worlds, though this one is designed specifically for use with syntastic, and thus will not run the same way as the previous JSXHint wrapper.
