1. Overview & Native Capabilities

Clerk is a leading authentication platform designed for React, Next.js, and modern full-stack web applications. Nativine bridges Clerk's web session tokens directly with native Android and iOS storage vaults:

One-Tap Social Sign-In: Launch native Apple Sign-In and Google One Tap dialogs that sync directly with your Clerk user account database.
Session Token Persistence: Securely persist Clerk session tokens (__session) in native OS keychains to keep users logged in indefinitely across app restarts.
Multi-Factor Authentication (MFA): Native TOTP authenticator prompts and SMS code autofill on mobile devices.

2. Configuration & App Builder Setup Guide

💼 Enterprise & Higher Plans Notice: Clerk Authentication is available on Nativine Enterprise and Custom plans (or enabled on request). When unlocked for your account, this add-on appears in the App Builder under Add-ons & Plugins.

3. Native JS Bridge API Reference

To initialize native social sign-in via Clerk or exchange authentication tokens programmatically, call the nativine.clerk.signIn() function:

JavaScript

nativine.clerk.signIn({
  strategy: 'oauth_apple',
  publishableKey: 'pk_live_xxxx',
  callback: 'onClerkAuthSuccess',
  onError: 'onClerkAuthError'
});

Parameters

Parameter	Type	Description
`strategy`	string	Required. Auth strategy identifier (e.g., `oauth_google`, `oauth_apple`, `ticket`).

`callback`	string	Optional. Name of JavaScript callback function receiving the Clerk session token.

4. Frequently Asked Questions (Q&A)

Does Clerk authentication require Apple Sign-In on iOS?

Yes. If you offer Google social sign-in via Clerk, Apple App Store guidelines mandate offering Sign in with Apple. Nativine handles Apple Sign-In compliance natively.

Do users stay logged in when force-closing the app?

Yes. Nativine caches the Clerk JWT token in native iOS Keychain and Android EncryptedSharedPreferences, ensuring zero session loss.
