There's no error, but I cant reach navigate function, which is coming next to await insert function.Īnd I keep getting warning that saids "Possible Unhandled Promise Rejection (id: 0)"īelow is my code to use SQLite. Press Ctrl+C to exit.I installed expo-sqlite to init, insert, and fetch some data.īut I cant insert data in the first place. › Scan the QR code above with Expo Go (Android ) or the Camera app (iOS ) › Metro waiting on exp://192.168.104.200:19000 Working with SQLite Compared to AsyncStorage and MMKV, SQLite is not only a simple key/value store it is a complete database engine that includes. Starting project at /Users/mac/Desktop/sammy/ReactAmplifyDataStoreExpo To use the local CLI instead (recommended in SDK 46 and higher ), run: This command is being executed with the global Expo CLI. ➜ ReactAmplifyDataStoreExpo git: (master ) ✗ expo start Head over to amplify/backend/api/aphql, delete the content, and add these lines of code. macOS: The default SQLite database is located at /usr/local/var/lib/grafana. In our app, we will create a schema for a simple contact application. Do not change this option unless you are working on Grafana development. The schema contains data types and relationships that represent the app's functionality. The first step to building an app backed by datastore is by defining a schema. Next, we go on to create the model for our application. This is an asynchronous, unencrypted, persistent, key-value storage system for React Native.It allows you to get information on Connection type and Connection quality this package is the React Native Network Info API for Android, iOS, macOS, Windows & Web.expo-file-system: This package provides access to the local file system on the device.expo-sqlite: this package gives the app access to a database that can be queried through a WebSQL-like API.this is the SQLite storage adapter for Amplify Datastore.aws-amplify: this package will enable us to build our AWS cloud-enabled mobile application.Amplify ships with default Storage Adapter implementations, such as SQLite and IndexedDB.Įnter fullscreen mode Exit fullscreen mode With DataStore, at runtime models are passed into a Storage Engine that has a Storage Adapter. We wont go the other way, and try to replace native SQLite with WASM+SQLite+OPFS on iOS or Android, because we have native code on those platforms that also. ![]() DataStore provides data modeling using GraphQL and converts it to models that you can use in building JavaScript, Android, iOS, and Flutter applications. This programming model ensures that working with distributed or shared data is as easy as working with local data. DataStore provides a model for using distributed or shared data without writing any additional code for implementing online and offline states. For that, software developer should be able to concern more on creative development of. The database is persisted across restarts of your app.ĭatastore allows you to interact with your data offline first, and it has a sync engine behind the scenes to send data to the backend. 3 Web development should be an art of creativity to deliver what the clients yearn for. Expo has an adapter that gives your app access to a database that can be queried through a WebSQL-like API called expo-sqlite. In this article, we will be building a mobile application with React Native using Expo SQLite adapter as a storage adapter for DataStore.īy the end of the of article, you will be able to build a contact app using the SQLite adapter for storage as shown in the video below:Įxpo enables developers to create hybrid JavaScript applications from the comfort of their terminals.
