Manage Users

Create User​

Developers can call the following login methods to sign in or create a user:

Get Currently Logged-in User​

Subscribe to Callback Function for Login State Changes​

To get the current user, it is recommended to set a callback function on the Auth object. This function will be triggered whenever the user's login state changes and will provide the current LoginState:

import cloudbase from "@cloudbase/js-sdk";

const app = cloudbase.init({
  env: "your-env-id"
});
const auth = app.auth();

// Set an observer
auth.onLoginStateChanged((loginState) => {
  if (loginState) {
    // The user is now logged in
  } else {
    // Not logged in
  }
});

Directly Get Current User​

You can also use the Auth.currentUser property to get the currently logged-in user. If the user is not logged in, currentUser is null:

const user = auth.currentUser;

if (user) {
  // The user is now logged in
} else {
  // Not logged in
}

Get User Profile​

You can obtain the user's profile information through various properties of the User object:

const user = auth.currentUser;
let uid, nickName, gender, avatarUrl, location;

if (user) {
  // Cloud Base unique user ID
  uid = user.uid;

  // Nickname
  nickName = user.nickName;

  // Gender
  gender = user.gender;

  // Avatar URL
  avatarUrl = user.avatarUrl;

  // User geographic location
  location = user.location;
}

Update User Profile​

You can use the User.update method to update the user's profile information. For example:

const user = auth.currentUser;

user
  .update({
    nickName: "Tony Stark",
    gender: "MALE",
    avatarUrl: "https://..."
  })
  .then(() => {
    // User information is updated successfully.
  });

Refresh User Profile Information​

For a multi-device application, users may update their personal information on one device, and other devices may need to refresh the information:

const user = auth.currentUser;

// Refresh user information.
user.refresh().then(() => {
  // After refreshing, the obtained user information will be the latest.
  const { nickName, gender, avatarUrl } = user;
});
