SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill provides reusable patterns for secure local data persistence in a React Native Fitness Tracker app by standardizing MMKV storage usage and Expo SecureStore encryption.

Core Features & Use Cases

  • Encrypted MMKV storage initialization and key management.
  • Helper utilities for save/load/remove/clear operations with typed data.
  • Seamless MST (MobX State Tree) integration for persisted stores via onSnapshot/applySnapshot.
  • Clear separation between sensitive data and cached values using dedicated storage instances.
  • Practical example: persisting user preferences, tokens, and small configuration data.

Quick Start

Initialize an encrypted MMKV instance in app/utils/storage and use the provided helpers to store and retrieve data.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up encrypted local storage in React Native using MMKV?▼

Encrypted local storage in React Native using MMKV is set up by initializing an encrypted MMKV instance and integrating Expo SecureStore for key management. The skill provides helper utilities for initialization, CRUD operations, and typed data handling.

Can I persist MobX State Tree snapshots to encrypted storage in React Native?▼

Yes, MobX State Tree snapshots can be persisted to encrypted storage using onSnapshot and applySnapshot. This skill provides seamless MST integration patterns that connect your state architecture directly to encrypted MMKV storage instances.

What is the best way to separate sensitive tokens from cached values in React Native storage?▼

The best way to separate sensitive tokens from cached values is using dedicated storage instances. This skill implements a clear separation pattern between sensitive data secured with Expo SecureStore and standard cached values using MMKV.

Does Expo SecureStore work with MMKV for encrypting user preferences in React Native?▼

Yes, Expo SecureStore works with MMKV to encrypt user preferences in React Native. The skill combines MMKV-based persistence patterns with SecureStore integration, handling key management and secure data operations for small configuration data.

How do I manage encryption keys for React Native local storage?▼

Encryption keys for React Native local storage are managed through Expo SecureStore integration. The skill provides initialization and key management patterns that securely handle encryption keys for your MMKV storage instances.

When should I not use MMKV for React Native data persistence?▼

MMKV for React Native data persistence is not ideal for large datasets or complex relational data. This skill targets small configuration data, user preferences, and tokens, using dedicated storage instances to separate cached values from sensitive information.
