Explore these in-depth production guides to learn how to build common use cases with Store. Learn how to support queries and mutations in your Store. Learn how to implement an offline-first architecture using Store and SqlDelight, enabling your app to provide seamless data access even without a network connection. Master data synchronization between local and remote sources using `MutableStore`, including strategies for detection and resolution to maintain data integrity. Implement robust error handling and retry mechanisms with Store, ensuring your app gracefully recovers from network failures and provides a reliable user experience. Integrate authentication flows with Store to manage secure data access, handle token refresh, and protect sensitive information within your application. Learn to handle real-time data streams using Store, incorporating WebSockets or Server-Sent Events to keep your app's data instantly up-to-date. Navigate the challenges of managing complex relational data structures with Store, including nested data and associations like comments, ratings, and user profiles. Optimize your app's performance with advanced caching strategies in Store, customizing cache policies, eviction strategies, and managing cache size limitations. Ensure the reliability of your data layer by learning best practices for testing Stores, Fetchers, and Source of Truth implementations in your applications. Explore how to effectively use Store in a Kotlin Multiplatform project, sharing code across Android, iOS, and other platforms with consistent behavior. Connect Store with modern UI frameworks, enabling reactive and responsive interfaces driven by Store's data streams. Learn strategies for migrating your existing data management solutions to Store, minimizing disruption and leveraging Store's powerful features. Implement data encryption and security best practices with Store to protect sensitive data stored locally and ensure compliance with security standards. Utilize `StoreMultiCache` to cache lists of items (collections) and decompose them into individual items (singles). This allows efficient caching and retrieval of both the entire collection and its individual elements. Implement `Validator` in your Store to check if cached data is still valid before emitting it to the UI or caching it. This can include time-based validation or custom logic to determine data validity. Connect Store's data streams to your state management solution to ensure the UI reacts to data changes efficiently. Learn how to set up primary and secondary fetchers, enabling your app to automatically switch to alternative data sources or strategies when the primary fetcher fails. Discover how to efficiently load large datasets by implementing pagination and infinite scrolling with Store, providing smooth user experiences when browsing extensive lists.
