What is an offline-first mobile architecture?

Offline-first is a design approach where an app functions primarily using local data, ensuring it remains usable without internet. Data is synchronized with a server in the background whenever connectivity is available.

Which storage engine does this skill recommend for React Native?

The skill recommends MMKV for simple, high-speed key-value storage due to its performance, while suggesting SQLite or WatermelonDB for complex queries and larger datasets.

Can this skill help with background synchronization?

Yes, it includes strategies for using NetInfo listeners to automatically trigger sync queues and process pending updates the moment the device regains network connectivity.

How does this skill handle data conflicts?

It provides implementation patterns for both 'Last-Write-Wins' (comparing timestamps) and manual resolution strategies where the user can choose which version of the data to keep.

Mobile Development

Implement robust local storage, data synchronization, and conflict resolution strategies for offline-capable mobile applications.

About

This skill provides Claude with specialized knowledge to architect and implement offline-first mobile applications, focusing on React Native and cross-platform ecosystems. It covers selecting optimal storage engines like MMKV or WatermelonDB, implementing optimistic UI updates for better user experience, managing background data synchronization, and handling complex data conflict resolution scenarios. It is particularly useful for developers building mission-critical apps that must function reliably in low-connectivity environments or require high-performance local data persistence.

Key Features

Implementation patterns for optimistic UI updates and sync queuing
Background synchronization strategies using network status monitoring
Expert guidance on local storage selection (MMKV, SQLite, WatermelonDB)
0 GitHub stars

Conflict resolution logic including last-write-wins and manual resolution

Use Cases

Building mobile apps that require full functionality without a stable internet connection
Managing complex data synchronization between local devices and remote servers
Optimizing app responsiveness by implementing local-first data persistence
