Having dabbled a bit with React / Redux, and while doing so used both the Import statement from ES6 and the Require function of Browserify, I decided I needed a RegEx to replace all "require" lines to "import" lines.
This is what I came up wit, so far:
const\s+(\w+)\s+=\s+require\('([^']+)'\);?
and replace with;
import $1 from '$2';
