IonChat Firebase v3 Messenger is a full fledged messenger app that synchronises real time with the Firebase v3 Database. Changes done on the Firebase back-end should reflect properly with the running app. The kit users a number of watchers, sockets, filters, and services to implement real time sync with our Firebase v3 Database. More on the implementation structure will be discussed in the lower sections. The messenger supports one-to-one friend messaging, group messaging, friend management, and profiles.
