Since its initial release in 2014, Couchbase Mobile has facilitated various application use cases, with common patterns emerging for its usage in app development. This blog post explores these patterns, focusing on Couchbase Lite, and is aimed at those already familiar with Couchbase Mobile. It covers four main patterns: handling large volumes of public, non-user specific data by preloading databases to reduce startup times; segregating client-local and synced data to facilitate access control and operational scope; supporting multi-user apps by creating separate database instances for each user to ensure data segregation and access control; and sharing data between apps on a device by utilizing platform-specific mechanisms to reduce data transfer and storage costs. The post also addresses configurations for shared databases, detailing practical approaches on iOS and Android platforms, and concludes with an invitation for further engagement and acknowledgment of contributors to the discussion.
