React Native SQLite Database Integration

SQLite3 Native Plugin for React Native for both Android (Classic and Native), iOS.
Foundation of this library is based on Chris Brody’s Cordova SQLite plugin.

Characteristic:

• SQL transactions
• Android in pure Java and Native modes
• iOS and Android supported via identical JavaScript API.
• Pre-populated SQLite database import from application bundle and sandbox
• JavaScript interface via plain callbacks or Promises.

There are sample apps provided in the test directory that can be used in with the AwesomeProject generated by React Native. All you have to do is to copy one of those files into your AwesomeProject replacing index.ios.js.
The library has been tested with React 16.2 (and earlier) and XCode 7,8,9 - it works fine out of the box without any need for tweaks or code changes. For XCode 7,8 vs. XCode 6 the only difference is that sqlite ios library name suffix is tbd instead of dylib.
Version 3.2 is the first version compatible with RN 0.40.

How to use (iOS):
Step 1 - Install Dependencies
With CocoaPods:
This command should be executed in the root directory of your project

npm install –save react-native-sqlite-storage

Then add this to your Podfile which should be located inside the ios project subdirectory

pod ‘React’, :path => ‘../node_modules/react-native’
pod ‘react-native-sqlite-storage’, :path => ‘../node_modules/react-native-sqlite-storage’

Or use the sample Podfile included in the package by copying it over to iOS subdirectory and replacing AwesomeProject inside of it with the name of your project.

Refresh the Pods installation

pod install

OR

pod update

Done, skip to Step 2

Without CocoaPods:
This command should be executed in the root directory of your project

npm install –save react-native-sqlite-storage
react-native link

rnpm and xcode are dependencies of this project and should get installed with the module but in case there are issue running rnpm link and rnpm/xcode are not already installed you can try to install it globally as follows:

npm -g install rnpm xcode

After linking project should like this:

Step 1 - If rnpm link does not work for you then you can try manually linking according to the instructions below: Drag the SQLite Xcode project as a dependency project into your React Native XCode project

XCode SQLite libraries dependency set up

Add libSQLite.a (from Workspace location) to the required Libraries and Frameworks. Also, add sqlite3.0.tbd (XCode 7) or libsqlite3.0.dylib (XCode 6 and earlier) in the same fashion using Required Libraries view (Do not just add them manually as the build paths will not be properly set)

Step 2 - Application JavaScript require
Add var SQLite = require(‘react-native-sqlite-storage’) to your index.ios.js

var React = require(‘react-native’);
var SQLite = require(‘react-native-sqlite-storage’);

Step 3 - Write application JavaScript code using the SQLite plugin

Add JS application code to use SQLite API in your index.ios.js etc. Here is some sample code. For a full working example see test/index.ios.callback.js. Please note that Promise based API is now supported as well with full examples in the working React Native app under test/index.ios.promise.js

errorCB(err) {
console.log("SQL Error: " + err);
},

successCB() {
console.log("SQL executed fine");
},

openCB() {
console.log("Database OPENED");
},

var db = SQLite.openDatabase("test.db", "1.0", "Test Database", 200000, openCB, errorCB);
db.transaction((tx) => {
tx.executeSql('SELECT * FROM Employees a, Departments b WHERE a.department = b.department_id', [], (tx, results) => {
console.log("Query completed");

// Get rows with Web SQL Database spec compliance.

var len = results.rows.length;
for (let i = 0; i < len; i++) {
let row = results.rows.item(i);
console.log(
}

// Alternatively, you can use the non-standard raw method.

/*
let rows = results.rows.raw(); // shallow copy of rows Array

rows.map(row => console.log(
*/
});});
How to use (Android):
Step 1 - NPM Install

npm install –save react-native-sqlite-storage

Step 2 - Update Gradle Settings (located under Gradle Settings in Project Panel)

// file: android/settings.gradle
...

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

Step 3 - Update app module Gradle Build script (located under Gradle Settings in Project Panel)

// file: android/app/build.gradle
...

dependencies {
...
implementation project(':react-native-sqlite-storage')
}

Step 4 - Register React Package (this should work on React version but if it does not, try the ReactActivity based approach. Note: for version 3.0.0 and below you would have to pass in the instance of your Activity to the SQLitePluginPackage constructor

…
import org.pgsqlite.SQLitePluginPackage;

public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {

private ReactInstanceManager mReactInstanceManager;
private ReactRootView mReactRootView;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mReactRootView = new ReactRootView(this);
mReactInstanceManager = ReactInstanceManager.builder()
.setApplication(getApplication())
.setBundleAssetName("index.android.bundle") // this is dependant on how you name you JS files, example assumes index.android.js
.setJSMainModuleName("index.android") // this is dependant on how you name you JS files, example assumes index.android.js
.addPackage(new MainReactPackage())
.addPackage(new SQLitePluginPackage()) // register SQLite Plugin here
.setUseDeveloperSupport(BuildConfig.DEBUG)
.setInitialLifecycleState(LifecycleState.RESUMED)
.build();
mReactRootView.startReactApplication(mReactInstanceManager, "AwesomeProject", null); //change "AwesomeProject" to name of your app
setContentView(mReactRootView);
}
…

Alternative approach on newer versions of React Native (0.18+). Note: for version 3.0.0 and below you would have to pass in the instance of your Activity to the SQLitePluginPackage constructor
import org.pgsqlite.SQLitePluginPackage;

public class MainApplication extends Application implements ReactApplication {
......

/**
* A list of packages used by the app. If the app uses additional views
* or modules besides the default ones, add more packages here.
*/
@Override
protected List<ReactPackage> getPackages() {
return Arrays.<ReactPackage>asList(
new SQLitePluginPackage(), // register SQLite Plugin here
new MainReactPackage());
}}

Step 5 - Require and use in Javascript - see full examples (callbacks and Promise) in test directory.

// file: index.android.js

var React = require(‘react-native’);
var SQLite = require(‘react-native-sqlite-storage’)
…

Setting up your project to import a pre-populated SQLite database from an application for iOS

Step 1 - Create ‘www’ folder.

Create a folder called ‘www’ (yes must be called precisely what else things won’t work) in the project folder via Finder

Step 2 - Create the database file

Copy/paste your pre-populated database file into the ‘www’ folder. Give it the same name you are going to use in openDatabase call in your application

Step 3 - Add file to project

in XCode, right click on the main folder and select Add Files to ‘your project name’

Step 4 - Choose files to add

In the Add Files dialog, navigate to the ‘www’ directory you created in Step 1, select it, make sure you check the option to Create Folder Reference

Step 5 - Verify project structure

Ensure your project structure after previous steps are executed looks like this

Step 6 - Adjust openDatabase call

Modify your openDatabase call in your application adding createFromLocation param. If you named your database file in step 2 ‘testDB’ the openDatabase call should look like something like this:

…
1.SQLite.openDatabase({name : “testDB”, createFromLocation : 1}, okCallback,errorCallback);
// default - if your folder is called www and data file is named the same as the dbName - testDB in this example
2.SQLite.openDatabase({name : “testDB”, createFromLocation : “~data/mydbfile.sqlite”}, okCallback,errorCallback);
// if your folder is called data rather than www or your filename does not match the name of the db
3.SQLite.openDatabase({name : “testDB”, createFromLocation : “/data/mydbfile.sqlite”}, okCallback,errorCallback);
// if your folder is not in app bundle but in app sandbox i.e. downloaded from some remote location.
…

For Android, the www directory is always relative to the assets directory for the app: src/main/assets
