Makes it easier to use SQLite in your Ionic 2 app.

Ionix SQLite

This project aims to make it easier to work with SQLite in Ionic 2 apps.

As it has no actual dependencies on Ionic it could be used in other Cordova applications as well.

In case you wonder, Ionix stands for "Ionic eXtensions". It's a name chosen to suggest that this package is related to Ionic, but is not an official Ionic project.

Why not just use Ionic Native?

Ionic Native is a wonderful project that wraps many useful Cordova plugins including SQLite.

However this project offers a few more features in addition to wrapping the Cordova SQLite plugin:

• It works in the browser (both ionic serve and ionic run browser) and not just on Android/iOS/Windows, by defaulting to WebSQL when the Cordova plugin is not available. (Note: the WebSQL standard is deprecated and support for it may be removed from Chrome at some point. Not a big deal, it works for now and we'll figure out a workaround if and when we need to.)
• No need to wait for deviceready or Platform.ready(); this is handled for you.
• When opening a database you can speficy one or more SQL statements to e.g. create all the required tables, and it will return a Promise that resolves only when the db has been fully initialised.
• This project works with either the cordova-sqlite-storage or the cordova-plugin-sqlite-2 plugins. Install whichever you prefer.

Usage

Install with npm:

npm install --save ionix-sqlite

Import and use a follows:

import { SqlDatabase } from 'ionix-sqlite';
import { Item } from './item.model';

export class ItemService {

  private dbPromise: Promise<SqlDatabase>;

  constructor() {
    const createItemsTable = `
      CREATE TABLE IF NOT EXISTS items (
        id INTEGER PRIMARY KEY,
        title TEXT,
        description TEXT
      )
    `;
    this.dbPromise = SqlDatabase.open('items.db', [createItemsTable]);
  }

  getItems(): Promise<Item[]> {
    const select = 'SELECT id, title, description FROM items';
    return this.dbPromise
      .then(db => db.execute(select))
      .then(resultSet => {
        const items = [];
        for (let i = 0; i < resultSet.rows.length; i++) {
          const row = resultSet.rows.item(i);
          items.push({
            id: row.id,
            title: row.title,
            description: row.description
          });
        }
        return items;
      });
  }


  insertItems(): Promise<any> {
    let inserts: any = [
      'INSERT INTO items (id, title) VALUES ("1", "title A");',
      'INSERT INTO items (id, title) VALUES ("2", "title B");',
      'INSERT INTO items (id, title) VALUES ("3", "title C");'
    ];
    return this.dbPromise
      .then(db => db.executeBatch(inserts))
      .then(() => {
        console.log('Done!');
      }).catch( err => console.log(err) );
  }
  

}
