Can Sequelize be used in React native?

Yes, it is possible to use Sequelize, a popular object-relational mapper (ORM), in a React Native app. Sequelize is designed to be used with Node.js, but it can also be used in a React Native app by using the react-native-sqlite-storage package, which provides a wrapper for the SQLite database engine that can be used in a React Native app.

To use Sequelize in a React Native app, you will first need to install the sequelize and react-native-sqlite-storage packages using npm or yarn. Then, you can import the Sequelize class from the sequelize package and use it to create a new Sequelize instance, passing in the react-native-sqlite-storage module as the dialect option.

Here is an example of how you might use Sequelize in a React Native app:

import Sequelize from 'sequelize';
import SQLite from 'react-native-sqlite-storage';

const sequelize = new Sequelize('database', 'username', 'password', {
  dialect: 'sqlite',
  storage: SQLite,
});

const User = sequelize.define('user', {
  username: Sequelize.STRING,
  password: Sequelize.STRING,
});

User.sync()
  .then(() => User.create({
    username: 'john',
    password: 'doe',
  }))
  .then(jane => {
    console.log(jane.toJSON());
  });

In this example, we are using Sequelize to define a User model with a username and password field, and then creating a new user instance and saving it to the database.
