react-native-sqlite-2

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.

Getting started

Add react-native-sqlite-2 to your dependencies:

$ npm install react-native-sqlite-2 --save

Link native dependencies

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

iOS/macOS

If using cocoapods in the ios/ directory run

$ pod install

Android

Please make sure AndroidX is enabled in your project by editting android/gradle.properties and adding 2 lines:

android.useAndroidX=true
android.enableJetifier=true

Usage

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.

Using with PouchDB

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" });

Troubleshooting

Row too big to fit into CursorWindow (Android)

You can set a limited windowSizeBytes for CursorWindow and try-catch the exception by adding following code to your MainApplication.onCreate in MainApplication.java:

try {
  Field field = CursorWindow.class.getDeclaredField("sCursorWindowSize");
  field.setAccessible(true);
  field.set(null, 100 * 1024 * 1024); //the 100MB is the new size
} catch (Exception e) {
  if (DEBUG_MODE) {
    e.printStackTrace();
  }
}

Note that it requires Android 9 (API level 28).
