What's new

Transactions
Listen to a value's lifecycle and mutate it on the go. Transactions lets you register lifecycle functions with your storage instance such as onwrite, beforewrite, onread, ondelete. This allows for a better and more managed control over the storage and also let's you build custom indexes with a few lines of code. Refer to #104 issue more detail on this feature.

storage.transactions.register("object","onwrite",(key,value) => {
  //do something
})

Remember that these are not events but functions. If you register the same type of function twice, the later will take precedence.

useIndex
A hook that will take an array of keys and returns an array of values for those keys. This is supposed to work in combination with Transactions. When you have build your custom index, you will need an easy and quick way to load values for your index. useIndex hook actively listens to all read/write changes and updates the values accordingly.

const [posts, update,remove] = useIndex(postsIndex,"object",storage);

v0.5.5

Introducing useMMKVStorage Hook 🎉

Thanks to the power of JSI, we now have our very own useMMKVStorage Hook. Think of it like a persisted state that will always write every change in storage and update your app UI instantly. It doesn't matter if you reload the app or restart it. Here's a small demo:

Import MMKVStorage and useMMKVStorage Hook.

import MMKVStorage, { useMMKVStorage } from "react-native-mmkv-storage";

Initialize the MMKVStorage instance.

const MMKV = new MMKVStorage.Loader().initialize();

Next, in our component we are going to register our hook.

const App = () => {
  const [user, setUser] = useMMKVStorage("user", MMKV);

  return (
    <View>
      <Text>{user}</Text>
    </View>
  );
};

To update value of "user" in storage and your App component will automatically rerender.

setUser("andrew");


// or you can do this too anywhere in the app:
MMKV.setString("user", "andrew");

Head over to the docs for complete usage.

What's Fixed:

1. Fix #64 especially on iOS on reloading app when MMKV was not registered on JSI
2. Updated docs to correctly install library along with react-native-reanimated. #89 #90 @r0b0t3d
3. All hasKey functions in the indexer are now synchronous

v0.5.4

This release fixes a lot of issues with JSI and hopefully the library should build normally now in debug and release.

1. Rewrite keystore & keychain Logic in JSI to make synchronous initialization possible.
2. Fixed need type definitions for callback function params #79 @mateosilguero
3. FIxed return types for all functions that write to database. #75
4. Fixed Crash in release build due to java.lang.UnsatisfiedLinkError: Bad JNI version returned from JNI_OnLoad #68
5. Fixed build failing on android for some build environments #67
6. Fix app crashing when using clearStorage #82 @focux
7. Update docs to reflect latest changes and installation process
8. Fixed release build on ios failed due to lower deployment target.
