JavaScriptでFirebase9のサインアウト処理

Posted at

JavaScriptでFirebase9のサインアウト処理をコーディングします。
Firebase8とは微妙に異なるので、注意が必要です。

コメントアウトしている部分は、Firebase8のコードです。

//import firebase from 'firebase';
import {getAuth, signOut} from 'firebase/auth'; //firebase9

//const auth = firebase.auth();
const auth = getAuth(); //firebase9

//auth.signOut(); //ログアウト
signOut(auth).then(() => {
  console.log('Sign-out successful.');
}).catch((error) => {
  console.log('Sign-out execing.');
});
