Authorizer Example with React Native (Expo)

OAuth2 PKCE login flow using expo-auth-session plus @authorizerdev/authorizer-js (v3) for token refresh, profile, and revocation.

Configuration

Update the constants at the top of App.tsx:

const authorizerClientID = 'YOUR_CLIENT_ID'; // Client ID from the Authorizer dashboard
const authorizerURL = 'https://your-instance.example.com'; // Base URL of your Authorizer instance

Also add the app's redirect URI (printed on startup) to your client's authorized redirect URLs.

Authorizer v2 server is configured entirely via CLI flags (no .env / OS env vars), e.g.

./authorizer \
  --database-type sqlite --database-url authorizer.db \
  --url http://localhost:8080 \
  --jwt-type HS256 --jwt-secret <jwt-secret> \
  --encryption-key "$(openssl rand -hex 32)" \
  --client-id <client-id> --client-secret <client-secret> \
  --admin-secret <admin-secret>

All of the above are required as of 2.4.0 — the server exits at boot if any is missing. --url is this server's own address (not the apps allowed to call it, which is --allowed-origins).

Run

npm install
npm start        # expo start
