react-native-opaque

React Native client for the OPAQUE Protocol

Installation

npm install react-native-opaque

Usage

import * as opaque from 'react-native-opaque';

const password = 'sup-krah.42-UOI'; // user password

const { clientRegistrationState, registrationRequest } =
  opaque.client.startRegistration({ password });
// ...

Usage with React Native Web

Since on web the package uses Web Assembly under the hood, it needs to be loaded asynchronously. To offer the same API the module is loaded internally, but in addition the API offers a ready Promise that will resolve once the module is loaded and ready to be used.

import * as opaque from 'react-native-opaque';

const password = 'sup-krah.42-UOI'; // user password

opaque.ready.then(() => {
  const { clientRegistrationState, registrationRequest } =
    opaque.client.startRegistration({ password });
  // ...
});

The most convenient way to use this is to have loading page that waits for the ready Promise to resolve before rendering the actual app.

For example:

export default function LoadingApp() {
  const [opaqueModuleStatus, setOpaqueModuleStatus] = React.useState<
    'loading' | 'failed' | 'loaded'
  >('loading');

  React.useEffect(() => {
    async function waitForOpaque() {
      try {
        await opaque.ready;
        setOpaqueModuleStatus('loaded');
      } catch (e) {
        console.warn(e);
        setOpaqueModuleStatus('failed');
      }
    }

    waitForOpaque();
  }, []);

  if (opaqueModuleStatus === 'loading') return null;
  if (opaqueModuleStatus === 'failed')
    return <Text>Failed to load resources. Please reload the app.</Text>;

  return <App />;
}

Note: The ready Promise resolves right away on the native side.
