Environment Detection

isNative

The isNative property indicates whether the SDK is running inside a native Appo container (true) or a regular browser (false):

const appo = getAppo();
console.log(appo.isNative); // true inside Appo app, false in browser
console.log(appo.version);  // SDK version string

Using Feature APIs

All feature APIs are accessed as properties on the Appo instance:

const appo = getAppo();

// Request push permission (returns 'denied' in browser)
const status = await appo.push.requestPermission();

// Check biometrics availability (returns false in browser)
const available = await appo.biometrics.isAvailable();

// Store a value (uses localStorage in browser)
await appo.storage.set('key', 'value');

All APIs provide sensible fallbacks in the browser. See Browser Fallbacks for the complete fallback table.
