Building cross-platform mobile applications now frequently uses React Native. Nevertheless, managing local storage effectively might be difficult. A high-performance key-value storage library called MMKV can be used in this situation. We'll look at how MMKV can make local storage in your React Native applications simpler in this blog article.
What exactly is MMKV?
WeChat created the effective, portable, and user-friendly MMKV key-value storage library. Because it performs better and supports more platforms, it is intended to take the place of iOS's NSUserDefaults and Android's SharedPreferences. For greater efficiency, MMKV uses the write-ahead logging method in conjunction with mmap() to store the data in memory.
How to get started?
Follow these steps to start utilizing MMKV in your React Native project:
STEP 1 : Setting up the MMKV Library
- npm install @react-native-community/mmkv
STEP 2: Link the package
- react-native link @react-native-community/mmkv
STEP 3: Import and Initialize
Let's look at some code examples to understand how MMKV can be utilized efficiently now that it has been configured.
Storing the data:
Retrieving the data
Removing the data
Observing Changes in Advanced Usage
With the aid of MMKV, you can keep track of changes to particular keys and respond to them instantly.
Several-Process Mode
Multiple processes can share the same data thanks to MMKV's ability to operate in multi-process mode. When several instances of your program are being used at once, this can be helpful.
- const mmkv = new MMKV.Loader().setProcessMode(MMKV.MULTI_PROCESS).initialize();
Conclusion
MMKV is a strong tool that may make managing local storage in your React Native applications much simpler. It adds value to your toolkit thanks to its performance advantages, cross-platform compatibility, and additional functionality. You may improve the effectiveness and timeliness of your app's data handling by incorporating MMKV.Try using MMKV in your React Native project to see the impact it can have on the way you handle local storage.
