javascript - Auth firebase onAuthStateChange -


when user logs in successfully, redirected main page (which want), keeps refreshing time. idea reason be?

code:

firebaseapp.auth().onauthstatechanged(user => {      if(user){         console.log('user signed in', user);         window.location='/';      }else{         console.log('user not signed in');      } })

a guess; because code gets executed again after page loaded , keeps redirecting? if case wrap if or make sure code embedded on login page.

firebaseapp.auth().onauthstatechanged(user => {  if(user){     console.log('user signed in', user);     if(window.location.href != "/"){         window.location='/';     }  }else{     console.log('user not signed in');  }  })
