If the second instance is not opened from your application, then it have no authority to access that instance.

I would suggest using window.open from your application, then you can pass an additional parameter as per your requirements. This way you will have control over the other instance you have created.

Regarding your comment:

You can add multiple event listeners for you instance window to detect changes on them like (load, close, resize etc).

  componentDidMount() {
    let strWindowFeatures = 'location=yes'
    let URL = 'http://localhost:3001'
    let win3Instace = window.open(URL, '_blank', strWindowFeatures)

    win3Instace.addEventListener('load', (event) => {
      console.log('Instance 3 is loaded, add callback funtion here')
    })
  }

  • so lets suppose i open a new instance like let instance3=window.open(url, name, '') in new window, then do you have any idea if i can open url1, url2 in different tab in instance3, while my app is in instance1. – Bikash Burma Dec 22 '19 at 15:31
