How to use sqlite in RN(Reacct Native)


let's see how to use sqlite database in RN(React Native).


when we develop apps with RN(React Native), sometimes we need to use local database. for example, the the Japanese words app which I developed for Korean(일단공부(일본어 단어 공부) - JLPT 단어 공부) is not to download the words, just use the local database. in this blog, I will introduce how to use the database in the app.

in here, I will introduce sqlite DB, and how to use it by react-native-sqlite-storage library in RN(React Native).

Prepare DB

let’s prepare the DB to use in RN(React Native). in here, we will make the sample database. if you have the sqlite database, please skip this section.

the link below is the sqlite tool which I use. click the link and download for your OS.

after downloading and installing, execute the tool.

RN(react-native) sqlite tool

click New Database on the left top, and create the database named TestDB.

RN(react-native) sqlite tool - create DB

create test table like below, and add id, name, age, email fields.

RN(react-native) sqlite tool - create DB table

execute the sql below to add dummy data.

	(name, age, email)
	("aaa",  20, ""),
	("bbb",  25, "bbb@bbb.bbb"),
	("ccc",  30, "ccc@ccc.ccc")

RN(react-native) sqlite tool - add data to DB

execute the sql below to check data is inserted well.

now, we prepared the database. let’s use it on RN(React Native).

Install react-native-sqlite-storage library

execute the command below on the project that you want to use the sqlite.

npm install --save react-native-sqlite-storage
# for typescript
npm install --save-dev @types/react-native-sqlite-storage

and then, execute the command below to bind react-native-sqlite-storage to RN(React Native) project.

react-native link react-native-sqlite-storage

if you use pod, I recommend you to bind it manually. you can see the details on the official site.

as a result, your project settings to use react-native-sqlite-storage should be like below.

Add DB

we need to add DB which we’ve made above to each OS.


if you want to use sqlite DB that you’ve made, you should follow the process below.

  1. create ios/[project name]/www folder and copy the DB on it. react-native-sqlite-storage create www folder and copy db file

  2. execute [project name].xcodeproj or [project name].xcworkspace file to start xcode

  3. right-click [project name] > [project name] folder on the left top and click Add Files to [project name]. react-native-sqlite-storage add db file on xcode

  4. when you see the file selection dialog, click www folder that we’ve made on (1) section. select Create folder references and click Add to add it. react-native-sqlite-storage add DB file to proejct


if you want to use sqlite DB that you’ve made, you should follow the process below.

  1. open and modify android/settings.gradle file like below. = 'react_native_sqlite_storage_exercise'
      include ':react-native-sqlite-storage'
      project(':react-native-sqlite-storage').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-sqlite-storage/src/android')
      include ':app'
  2. oepn and modify android/app/build.gradle file like below.
      dependencies {
       implementation fileTree(dir: "libs", include: ["*.jar"])
       implementation "${rootProject.ext.supportLibVersion}"
       implementation "com.facebook.react:react-native:+"  // From node_modules
       implementation project(':react-native-sqlite-storage')
  3. open and modify file like below.
      import org.pgsqlite.SQLitePluginPackage;
      public class MainApplication extends Application implements ReactApplication {
     protected List<ReactPackage> getPackages() {
       return Arrays.<ReactPackage>asList(
         new SQLitePluginPackage(),
         new MainReactPackage()
  4. create android/app/src/main/assets/www folder and copy the sqlite DB which you’ve made react-native-sqlite-storage add db file on android

How to use DB

when you finished the configuration each OS, you can use sqlite DB by adding the source like below.

import * as React from 'react';
import Styled from 'styled-components/native';
import SQLite from 'react-native-sqlite-storage';

const Container = Styled.View`
  flex: 1;
  justify-content: center;
  align-items: center;
  background-color: #F5FCFF;
const UserContainer = Styled.View`
  flex-direction: row;
const UserInfo = Styled.Text`
  padding: 8px;

interface Props {}
interface State {
  db: SQLite.SQLiteDatabase;
  users: Array<IUser>;

export default class App extends React.Component<Props, State> {
  constructor(props: Props) {

    const db = SQLite.openDatabase(
        name: 'TestDB.db',
        location: 'default',
        createFromLocation: '~www/TestDB.db',
      () => {},
      error => {

    this.state = {
      users: [],

  render() {
    const { users } = this.state;
    return (
        { IUser, index: number) => (
          <UserContainer key={`user-info${index}`}>

  componentDidMount() {
    const { db } = this.state;

    db.transaction(tx => {
      tx.executeSql('SELECT * FROM test;', [], (tx, results) => {
        const rows = results.rows;
        let users = [];

        for (let i = 0; i < rows.length; i++) {

        this.setState({ users });

  componentWillUnmount() {
    const { db } = this.state;



we saw how to use react-native-sqlite-storage library to use the sqlite DB. now, if you want to deploy the app with DB, you can use the sqlite database. let’s challenge!

if you want to know full example about how to use react-native-sqlite-storage, please check the git repository below that I’ve made when I wrote this blog.
