Nativescript-Angular Integration with TypeORM

• NativeScript : Runs Javascript as Native apps on Android and iOS
• Angular: A frontend framework that can be used in NativeScript
• nativescript-sqlite: A Sqlite library for {N}, used here as the Sqlite driver
• TypeORM: A TypeScript/ES7 based ORM that works on NodeJS as well as browsers

Demo

As you can see the task list is persisted even when the app is killed and reopened.

Connection

import {createConnection, getManager} from "typeorm/browser";
import Todo from './models/Todo';
//driver
let driver = require('nativescript-sqlite');

(async () => {
    try {
        const connection = await createConnection({
            database: 'test.db',
            type: 'nativescript',
            driver,
            entities: [
                Todo
            ],
            logging: true
        })

        console.log("Connection Created")

        // setting true will drop tables and recreate
        await connection.synchronize(false) 

        console.log("Synchronized")


    } catch (err) {
        console.error(err)
    }
})();
