React Native SQLite 2

SQLite3 Native Plugin for React Native for Android/iOS/Windows. 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 with react-native-sqlite-storage. It works pretty well with PouchDB on React Native app.

The reason of this plugin is that react-native-sqlite-storage has some problems to use 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 avoids these problems.

Getting started

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

Mostly automatic installation

$ react-native link react-native-sqlite-2

iOS

In Xcode, add libsqlite3.tbd to your project's Build Phases ➜ Link Binary With Libraries.

Manual installation

iOS

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-sqlite-2 and add RNSqlite2.xcodeproj
3. In Xcode, in the project navigator, select your project. Add libRNSqlite2.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

Android

1. Open up android/app/src/main/java/[...]/MainActivity.java

• Add import dog.craftz.sqlite_2.RNSqlite2Package; to the imports at the top of the file
• Add new RNSqlite2Package() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-sqlite-2'
   project(':react-native-sqlite-2').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-sqlite-2/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

   compile project(':react-native-sqlite-2')
   

Windows

1. Open the solution in Visual Studio for your Windows apps.

• Right click your solution file in the Explorer and click Add > Existing Project....

• [UWP] Navigate to ./<app-name>/windows/RNSqlite2/ and add RNSqlite2.csproj.

  [WPF] Navigate to ./<app-name>/windows/RNSqlite2.Net46/ and add RNSqlite2.Net46.csproj.

• Right click on your React Native Windows app under your solutions directory and click Add > Reference....

• [UWP] Check the RNSqlite2 you just added and press Ok.

  [WPF] Check the RNSqlite2.Net46 you just added and press Ok.

2. Open MainPage.cs in your app

• Edit it like below:

using RNSqlite2;

get
  {
      return new List<IReactPackage>
      {
          new MainReactPackage(),
          new RNSqlite2Package(),
      };
  }

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' })
