version.js

//  Updates iOS & Android App Version
//  ===================
//
//  This script extends `npm version` functionality to also
//  update the version number in Info.plist for the App Store,
//  and the versionCode and versionName for Google Play Store.
//
//  It runs after package.json version is updated, but before git commit.
//
//  See https://docs.npmjs.com/cli/version for more info.
//
//
//  ### Install
//
//  Add to package.json scripts {
//    "version": "node ./version.js",
//  }
//
//  ### Usage
//
//  "npm version [major|minor|patch]"
//
