Kinde Expo SDK

The Kinde Expo SDK allows developers to quickly and securely integrate a new or an existing Expo application into the Kinde platform.

Installation

npx nypm add @kinde/expo

Environment variables

The redirection URL is automatically computed using Expo Auth Session makeRedirectUri function. You can find more information about this function here.

Integrate with your app

Setup the Kinde Provider in your App.js file.

import { KindeAuthProvider } from '@kinde/expo';

export default function App() {
  return (
    <KindeAuthProvider config={{
       domain: "https://your-app.kinde.com", // Required
       clientId: "your-client-id", // Required
       // Optional (default: "openid profile email offline")
       scopes: "openid profile email offline",
     }}>
      <!-- Your application code -->
    </KindeAuthProvider>
  );
}

Authentication Methods

Simple and flexible functions for register, login and logout are part of the useKindeAuth hook

import { useKindeAuth } from "@kinde/expo";
import { Pressable, View, Text } from "react-native";

export default function Authentication() {
  const kinde = useKindeAuth();

  const handleSignUp = async () => {
    const token = await kinde.register({});
    if (token) {
      // User was authenticated
    }
  };

  const handleSignIn = async () => {
    const token = await kinde.login({});
    if (token) {
      // User was authenticated
    }
  };

  const handleLogout = async () => {
    await kinde.logout({ revokeToken: true });
  };

  return !kinde.isAuthenticated ? (
    <View>
      <Pressable onPress={handleSignIn}>
        <Text>Sign In</Text>
      </Pressable>
      <Pressable onPress={handleSignUp}>
        <Text>Sign Up</Text>
      </Pressable>
    </View>
  ) : (
    <Pressable onPress={handleLogout}>
      <Text>Logout</Text>
    </Pressable>
  );
}

Using Utility Functions

All utility functions from @kinde/js-utils are available through @kinde/expo/utils and also through the useKindeAuth hook. This allows you to use these utilities directly in your Expo application.

import { getUserProfile, getFlag, getRoles } from "@kinde/expo/utils";

// Example usage
const checkUserProfile = async () => {
  const profile = await getUserProfile();
  console.log("User profile:", profile);
};

Common utility functions include:

• getUserProfile - Get the current user's profile
• getFlag - Check feature flag values
• getRoles - Get the current user's roles
• getCurrentOrganization - Get the current organization
• getUserOrganizations - Get all organizations the user belongs to
• getPermission - get a single permission value
• getPermissions - get all user permissions
• getClaim - Get a specific claim from the token
• getClaims - Get all claims from the token
• refreshToken - Manually refresh the access token
