React Native Quick WebSQL

This library provides a WebSQL-compatible API to store data in a react native app, by using a fast JSI implementation of the SQLite driver react-native-quick-sqlite.

Installation

yarn add react-native-quick-websql react-native-quick-sqlite
npx pod-install

Usage

See an example project for more detail.

import WebSQLite from "react-native-quick-websql";

const db = WebSQLite.openDatabase('mydb.db')
db.transaction(
  (txn) => {
    console.log('Running transaction')
    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 || 0); ++i) {
        console.log('item:', res.rows?.item(i))
      }
    })
  },
  (e) => {
    console.error(e)
  }
)

Limitations & Debugging

As the library uses JSI for synchronous native methods access, remote debugging (e.g. with Chrome) is no longer possible. Instead, you should use Flipper.
