how to get a list of users from firebase-CodePudding

function getUsersEmail() {
  const dbRef = ref(getDatabase());
  get(child(dbRef, `users/`  )).then((snapshot) => {
    if (snapshot.exists()) {
      console.table(snapshot.val());
    } else {
      console.log("No data available");
    }
  }).catch((error) => {
    console.error(error);
  });
}

I was able to output the database to the console. I would like to output only the email addresses of users.

JSON File

 {
"users": {
"2Le5WxOGnWWrkshsEqjeSIq527O2": {
  "email": "[email protected]",
  "password": "qweqwe"
},
"2jn1YmI9twce3ylEP8wiu5QhUDf1": {
  "email": "[email protected]",
  "password": "qweqwe"
},

CodePudding user response：

To retrieve all users and output only their email addresses:

get(child(dbRef, `users/`  )).then((snapshot) => {
  snapshot.forEach((child) => {
    console.log(child.val().email);
  })
});
