Queries

var database = firebase.database();

function writeUserData(userId, name, email, imageUrl) {
  firebase.database().ref('users/' + userId).set({
    username: name,
    email: email,
    profile_picture : imageUrl
  });
}

var starCountRef1 = firebase.database().ref('users/' + userId);
starCountRef1.on('value', function(snapshot) {
  updateStarCount(postElement, snapshot.val());
});

var starCountRef2 = firebase.database().ref('users/' + userId);
starCountRef2.on('value',(snapshot) => {
  updateStarCount(postElement, snapshot.val());
});

Multiple accounts

firebase.auth().signInWithPopup(provider).then(function(result) {
  // This gives you a Google Access Token. You can use it to access the Google API.
  var token = result.credential.accessToken;
  // The signed-in user info.
  var user = result.user;
  // ...
}).catch(function(error) {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  // The email of the user's account used.
  var email = error.email;
  // The firebase.auth.AuthCredential type that was used.
  var credential = error.credential;
  // ...
});

firebase.auth().createUserWithEmailAndPassword(email, password)
.catch((error) => {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  // ...
});

Storage

• Flexibility
• Real Time
• Not Conection
• Security

Code

// Create a root reference
var storage = firebase.app().storage("gs://my-custom-bucket");

// Create a reference to 'images/mountains.jpg'
var mountainImagesRef = storageRef.child('images/mountains.jpg');

var file = ... 
// use the Blob or File API
//Can Use (Strings, Bytes Array)

var uploadTask = ref.put(file).then(function(snapshot) {
  console.log('Uploaded a blob or file!');
});


// Pause the upload
uploadTask.pause();

// Resume the upload
uploadTask.resume();

// Cancel the upload
uploadTask.cancel();
