Rewind a compressed javascript to it's original project using sourcemap easily, such as your Borwserify project and Webpack project.
Make sure your packed js file and sourcemap are valid.
Use as a cli tool:
$ sudo npm install sourcemap-rewind -g
$ sourcemap-rewind -i app.js -o ./out
or
$ npm install sourcemap-rewind
then
const rewind = require('sourcemap-rewind');
rewind('Input/file/path.js','Output/directory/path');
