I am working on react-native version 0.56.0. I am trying to store data on device while app installation. How can I achieve this?
Thank you in advance.
Three options:
If you want to store a lot of data, you can use a database SQLite.
https://www.npmjs.com/package/react-native-sqlite-storage
If you want to store some data you can use AsyncStorage, it is very helpful and easy to use. (In your version it is ok, but now it is deprecated, you need to use community repository)
https://facebook.github.io/react-native/docs/0.56/asyncstorage
You can store your redux store in your app using a component called redux-persist. It if very helpfull to store the information that your application has and is optimized with AsyncStorage.

I want to build an app where users can jointly work on lists. The app should be avialable offline and sync changes when it goes online again.
For the app iteself, I've decided to go with Ionic Vue. For storage, I created a Firestore and was able to sync between my app and Firestore by using the Firesotre method onSnapshot() (doc). Although this working at the moment, the resulting code does not look very elegant and I have to create multiple very similar Firebase calls in different components. This slows the app down and (I think) also prevents me from making the lists available offline and sync them again when there is a connection.
I recently discovered vuex and the idea sounds quite fitting for my case: I store all app data in the vuex store and sync it (both ways) to Firestore. My components access the vuex store instead of the Firestore directly. Here are some questions regarding this idea:
Is this in general how the vuex store and Firestore are supposed to be used?
Can I make the vuex store data available on my phone and only sync it to the Firestore whenever there is a connection (to make the app available offline inlc. modifying data)?
If so, what is the easiest way to sync the vuex store to Firestore?
Regarding the syncing: I found Vuexfire, but it does not really work for me as expected - I guess this is because it is built on Vue 2 (as against Ionic which is built on Vue 3). I also found Vuex Easy Firestore, but I'm a bit reluctant to try new tools, as Vuexfire cost me several hours.
Thanks for reviewing my implementation ideas!
I'm about to start working on a expense tracker app for mobile and I would like to use React Native with Expo (pretty new to mobile techs). Maybe I will share it with some friends or other people and the question that cames up is where to store their data (in this case is sensitive as they will register their money's movement).
What I mean is, I could use any cloud DB (Mongo, Firestore, etc) but I will have access to everything they register there and I wouldn't like that, just for security and their privacy sake.
So, is there a way to store their data or everything they register locally in their phones? So the app can only access to the data that is stored there and I can't see it. Or any other possibility?
I found the AsyncStorage API but I don't know if this is the correct approach for what I'm looking for. I didn't code anything yet as I don't know which would be the right path.
You can use Secure Store since you're using expo.
expo-secure-store provides a way to encrypt and securely store key–value pairs locally on the device. Each Expo project has a separate storage system and has no access to the storage of other Expo projects.
See https://docs.expo.dev/versions/latest/sdk/securestore/
I had a similar case and i went for realm.js .
I'm switching from the AsyncStorage to the MMKV storage library and I'd like to know the best way to remove the old AsyncStorage data from the devices of my users. I don't need to migrate any data.
I know I could just call AsyncStorage.clear(), but ideally I'd like to remove the library completely from my project. If I remove AsyncStorage, does all data created on the device by it get deleted as well? If not, is there another way to clear the old storage which I'm not aware of?
Appreciate your input!
I'm stuck for making my react native app offline for storing the images.
what is the best way to use, shall i go with AsyncStorage, Real m, CouchDB or WatermelonDB.
Actually i am new to React Native, so i want to use the best solution.
Please help me.
Thanks in advance.
By the common ways. There are no databases actually store media. They actually save media files in physic / cloud servers and store only access url in database.
So, to achieve your technical goal. You can use react-native-fs to interact with your media files. And save their url into your database like Realm, PouchDB, AsyncStorage.
I think AsyncStorage is simple to setup and suitable for save media url.
I have a react native mobile application and I need some pages to work offline (without internet connection) I am using redux persist library.
My question is where to initialize the store and persist it?
Should I make it for each page or one time?
You use it to persist either your entire redux store, or a part of the store. If your not using redux yet then you will need to implement that first.
It’s setup at the same time you create your redux store.
There are links to several examples and a guide start guide in the GitHub project readme.
