Overview

Prerequisites: CloudBase environment ID (env) Prerequisites: CloudBase environment Region (region)

Core Capabilities

Use Case: Web frontend projects using @cloudbase/js-sdk@2.24.0+ for user authentication
Key Benefits: Compatible with supabase-js API, supports phone, email, anonymous, username/password, and third-party login methods @cloudbase/js-sdk cdn source: https://static.cloudbase.net/cloudbase-js-sdk/latest/cloudbase.full.js

Prerequisites

• Automatically use auth-tool-cloudbase to get publishable key and configure login methods.
• If auth-tool-cloudbase failed, let user go to https://tcb.cloud.tencent.com/dev?envId={env}#/env/apikey to get publishable key and https://tcb.cloud.tencent.com/dev?envId={env}#/identity/login-manage to set up login methods

Quick Start

import cloudbase from '@cloudbase/js-sdk'

const app = cloudbase.init({
  env: `env`, // CloudBase environment ID
  region: `region`,  // CloudBase environment Region, default 'ap-shanghai'
  accessKey: 'publishable key', // required, get from auth-tool-cloudbase
  auth: { detectSessionInUrl: true }, // required
})

const auth = app.auth
``

## Login Methods

**1. Phone OTP (Recommended)**
- Automatically use `auth-tool-cloudbase` turn on `SMS Login`
```js
const { data, error } = await auth.signInWithOtp({ phone: '13800138000' })
const { data: loginData, error: loginError } = await data.verifyOtp({ token:'123456' })

2. Email OTP

• Automatically use auth-tool-cloudbase turn on Email Login

const { data, error } = await auth.signInWithOtp({ email: '[e-mail]' })
const { data: loginData, error: loginError } = await data.verifyOtp({ token: '654321' })

3. Password

const { data, error } = await auth.signInWithPassword({ username: 'test_user', password: 'pass123' })
const { data, error } = await auth.signInWithPassword({ email: '[e-mail]', password: 'pass123' })
const { data, error } = await auth.signInWithPassword({ phone: '13800138000', password: 'pass123' })

4. Registration (Smart: auto-login if exists)

• Only support email and phone otp registration
• Automatically use auth-tool-cloudbase turn on Email Login or SMS Login

// Email Otp
const { data, error } = await auth.signUp({ email: '[e-mail]', nickname: 'User' })
const { data: loginData, error: loginError } = await data.verifyOtp({ token: '123456' })

// Phone Otp
const { data, error } = await auth.signUp({ phone: '13800138000', nickname: 'User' })
const { data: loginData, error: loginError } = await data.verifyOtp({ token: '123456' })

5. Anonymous

• Automatically use auth-tool-cloudbase turn on Anonymous Login

const { data, error } = await auth.signInAnonymously()

6. OAuth (Google/WeChat)

• Automatically use auth-tool-cloudbase turn on Google Login or WeChat Login

const { data, error } = await auth.signInWithOAuth({ provider: 'google' })
window.location.href = data.url // Auto-complete after callback

7. Custom Ticket

await auth.signInWithCustomTicket(async () => {
  const res = await fetch('/api/ticket')
  return (await res.json()).ticket
})

8. Upgrade Anonymous

const { data, error } = await auth.getSession()
const { data: signUpData, error: signUpError} = await auth.signUp({
  phone: '13800000000',
  anonymous_token: data.session.access_token,
})
await signUpData.verifyOtp({ token: '123456' })

User Management

// Sign out
const { data, error } = await auth.signOut()

// Get user
const { data, error } = await auth.getUser()
console.log(data.user.email, data.user.phone, data.user.user_metadata?.nickName)

// Update user (except email, phone)
const { data, error } = await auth.updateUser({ nickname: 'New Name', gender: 'MALE', avatar_url: 'url' })

// Update user (email or phone)
const { data, error } = await auth.updateUser({ email: '[e-mail]' })
const { data, error } = await data.verifyOtp({ email: "[e-mail]", token: "123456" });

// Change password (logged in)
const { data, error } = await auth.resetPasswordForOld({ old_password: 'old', new_password: 'new' })

// Reset password (forgot)
const { data, error } = await auth.reauthenticate()
const { data, error } = await data.updateUser({ nonce: '123456', password: 'new' })

// Link third-party
const { data, error } = await auth.linkIdentity({ provider: 'google' })

// View/Unlink identities
const { data, error } = await auth.getUserIdentities()
const { data, error } = await auth.unlinkIdentity({ provider: data.identities[0].id })

// Delete account
const { data, error } = await auth.deleteMe({ password: 'current' })

// Listen to state changes
const { data, error } = auth.onAuthStateChange((event, session, info) => {
  // INITIAL_SESSION, SIGNED_IN, SIGNED_OUT, TOKEN_REFRESHED, USER_UPDATED, PASSWORD_RECOVERY, BIND_IDENTITY
})

// Get access token
const { data, error } = const { data, error } = await auth.getSession()
fetch('/api/protected', { headers: { Authorization: `Bearer ${data.session?.access_token}` } })

// Refresh user
const { data, error } = await auth.refreshUser()
