IonicDB

IonicDB is a cloud-hosted real-time database without the worry of scalability, data management, and security. If you have any exposure working with Firebase or Parse, IonicDB is quite similar to those.

A simple example of using IonicDB is as follows:

import {Database} from '@ionic/cloud-angular'; 

@Component({ 
    selector: 'todos-page' 
}) 
export class TodosPage { 
    public todos: Array < string > ; 

    constructor(private db: Database) { 
        db.connect(); 
        db.collection('todos').watch().subscribe((todos) => { 
            this.todos = todos; 
        }, (error) => { 
            console.error(error); 
        }); 
    } 

    createTodo (todoText: string) { 
        this.db.collection('todos').store({ text: todoText, isCompleted: false }); 
    } 
}
