Petrus

The library handles authentication logic with token based flow.

Main features

• automatically refresh access token before it expires
• persisting tokens state in local or session storage (optional)
• automatically fetching an authorized user after successful tokens retrieval from a persistent storage
• simple API for auth state management: getAuthStateChannel, withAuthSession
• authorizable HOC - render content (a firewall, an authorized content or a loader) based on current auth. state

Requirements

The library relies on react, redux, react-redux, redux-saga and reselect packages as peer dependencies.

Usage with @ackee/antonio

With OAuth2

@ackee/petrus supports following OAuth2 flows:

• Implicit grant flow
  • Matches with the default configuration.
  • origin property is required
• Web application flow
  • Additionally to the Implicit grant flow, you have to provide the fetchAccessToken method.

See how to setup @ackee/petrus for these flows here.
