Chrome 'open tab' reuse an empty tab when possible

Merged Administrator requested to merge github/fork/n3tr/open-chrome-use-empty-tab into master

Created by: n3tr

Still WIP: need to clean up duplicated code and found some unexpected behavior (both in master and this branch)

on startscript - If there're no debugging tab (localhost:3000) open, we will try to use empty tab instead of create new one. (fixes #1157 (closed))

Test plan

To invoke script, We can use both npm/yarn start or run osascript openChrome.applescript localhost:3000 inside /packages/react-dev-utils folder .

  • No open chrome window: When chrome open with an empty tab, use the empty tab instead of create new one.
  • Chrome window with debugging tab: Reuse debugging tab.
  • Chrome window w/o debugging tab: Create new tab with url.
  • Chrome window w/o debugging tab, but have an empty tab: Use empty tab.
# Setup
npm run create-react-app my-app
cd my-app
yarn start

Test env

  • Browser: Google Chrome Version 54.0.2840.98
  • OS: macOS Sierra 10.12.1
