What is React Native MMKV Storage?

This library provides a fast, reliable data storage solution for React Native, enabling you to store various data types across multiple database instances efficiently. Thanks to its use of C++ and JSI, it’s one of the fastest available options.

Breaking Changes in Version 0.9.0

Note that this library works only with React Native version 0.71.0 and above. If you are using an older version, you should stick with 0.8.x until you upgrade.

Features Overview

• Written in C++ using JSI: Offers high-speed storage functionality.
• Simple and Lightweight: Minimal size footprint for Android (50K) and iOS (30K).
• Fast and Efficient: Reads and writes in 0.0002 seconds using advanced techniques.
• Reactive Storage: Uses useMMKVStorage and useIndex hooks for real-time updates.
• Lifecycle Control: Manage data lifecycles with transaction management.
• Multi-Process Support: Allows concurrent access from various processes.
• Full Encryption Support: Utilizes AES CFB-128 for secure data storage.
• Supports redux-persist: Seamlessly integrate with Redux.

Understanding with an Analogy

Think of MMKV Storage as a modern filing cabinet in an office where you can store files (data) in separate drawers (database instances). Each drawer is specifically designed for certain types of files—imagine having a drawer labeled ‘Personal’, another labeled ‘Work’, and so forth. When you need to retrieve a file, you can quickly open the respective drawer, find the folder, and access what you need in the blink of an eye! This makes organizing and accessing your data both fast and efficient, akin to how the MMKV library operates with various types of data and different instances.

Troubleshooting

If you run into any issues while using React Native MMKV Storage, consider these troubleshooting tips:

• Ensure you have the correct version of React Native installed. If using 0.9.0+, upgrade accordingly.
• Check your installation command for errors.
• Refer to the comprehensive documentation for any feature-specific issues.
