How stop after running react-scripts start?

Question

I started a React app with npm start with start defined in package.json:

{
  "name": "testreactapp",
  "version": "0.1.0",
  "private": true,
  "dependencies": {
    "react": "^15.6.1",
    "react-dom": "^15.6.1",
    "react-scripts": "1.0.10"
  },
  "scripts": {
    "start": "react-scripts start",
    "build": "react-scripts build",
    "test": "react-scripts test --env=jsdom",
    "eject": "react-scripts eject"
  }
}

I want to stop it now, without closing the terminal. How do I do that?

Tried: npm stop testrectapp but that throws error that it needs a script

Then tried: npm run stop with script "stop": "pkill --signal SIGINT testreactapp" that throws error 'pkill is not recognized as a command'

Edit

Running ps in bash shows:

      PID    PPID    PGID     WINPID   TTY         UID    STIME COMMAND
     6652       1    6652       6652  ?         197612 19:52:49 /usr/bin/mintty
     1092       1    1092       1092  ?         197612   Jul 25 /usr/bin/mintty

Don't see the app there?

Hit your keyboard shortcut for stopping terminal commands (usually Ctrl+C or Ctrl+Q)

Or, if you don't have input access to the process, identify its PID and kill it :

On Windows :

C:\>Taskkill /PID <PID> /F

On Linux :

$>kill -SIGTERM <PID>
