authentication-passport package

An adapter to plug in passport based strategies to the authentication system in @loopback/authentication @3.x.


@loopback/authentication @3.x allows users to register authentication strategies that implement the interface AuthenticationStrategy.

Since AuthenticationStrategy describes a strategy with different contracts than the passport Strategy, and we’d like to support the existing 500+ community passport strategies, an adapter class is created in this package to convert a passport strategy to the one that LoopBack 4 authentication system wants.
