webpack-resolve-short-path-plugin/lib/resolveShortPath.js

A plugin for enhanced-resolve (Webpack v2) that resolves paths like ~module to %rootPath%/module so you don't have to write relative paths like ../../../module.

var path = require('path');

module.exports = function(rootPath, shortPath) {
  return path.join(rootPath, shortPath.substr(1));
};
