SQLite3 Native Plugin for React Native for Android, iOS, Windows and macOS. This plugin provides a WebSQL-compatible API to store data in a react native app, by using a SQLite database on the native side.
Inspired by fantastic work done by Nolan Lawson. It should be a drop-in replacement for react-native-sqlite-storage. It works pretty well with PouchDB on React Native app.
The reason for this plugin is that react-native-sqlite-storage
has some problems when used with PouchDB:
- It can't store string data with
\u0000
due to the react native problem.- PouchDB heavily uses the Null character in the document IDs for building index, so it won't work well.
- It's unstable for storing PouchDB's attachments: #6037.
This plugin solves these problems.
Even the latest version of Android is several versions behind the latest version of SQLite, whereas iOS has newer version. React Native SQLite 2 uses sqlite-android which allows you to use the latest version of it with new SQLite features enabled:
Add react-native-sqlite-2 to your dependencies:
$ npm install react-native-sqlite-2 --save
From react-native 0.60 autolinking will take care of the link step but don't forget to run pod install
.
$ react-native link react-native-sqlite-2
If using cocoapods in the ios/
directory run
$ pod install
Please make sure AndroidX is enabled in your project by editing android/gradle.properties
and adding 2 lines:
android.useAndroidX=true
android.enableJetifier=true
import SQLite from 'react-native-sqlite-2'
const db = SQLite.openDatabase('test.db', '1.0', '', 1)
db.transaction(function(txn) {
txn.executeSql('DROP TABLE IF EXISTS Users', [])
txn.executeSql(
'CREATE TABLE IF NOT EXISTS Users(user_id INTEGER PRIMARY KEY NOT NULL, name VARCHAR(30))',
[]
)
txn.executeSql('INSERT INTO Users (name) VALUES (:name)', ['nora'])
txn.executeSql('INSERT INTO Users (name) VALUES (:name)', ['takuya'])
txn.executeSql('SELECT * FROM `users`', [], function(tx, res) {
for (let i = 0; i < res.rows.length; ++i) {
console.log('item:', res.rows.item(i))
}
})
})
There is a test app in the test directory.
It can be used with pouchdb-adapter-react-native-sqlite.
import PouchDB from 'pouchdb-react-native'
import SQLite from 'react-native-sqlite-2'
import SQLiteAdapterFactory from 'pouchdb-adapter-react-native-sqlite'
const SQLiteAdapter = SQLiteAdapterFactory(SQLite)
PouchDB.plugin(SQLiteAdapter)
var db = new PouchDB('mydb', { adapter: 'react-native-sqlite' })
As part of database initialization, this library will enable foreign key support automatically on both iOS & Android. Thus, any tables that define foreign key constraints will have them enforced whether or not foreign key support is explicitly enabled/disabled by PRAGMA statements sent via SQL.
