Nullables Livestream #4: State-Based Notifier

In this weekly livestream series, I pair up with Ted M. Young, aka jitterted, to look at Nullables and A-Frame Architecture as an alternative to Mocks, Spies, and Hexagonal Architecture. Each episode combines a healthy dose of architecture and design discussion with hands-on coding.

Watch us live every Monday! For details, see the event page. For more episode recordings, see the episode archive.
