Use your model class in your app (React Example)

import modelStore from 'ModelStore';

class App extends React {
	async componentDidUpdate() {
		if (!modelStore.isInitialized) {
		  modelStore.setName("dbName");	// to set databasename for model
		  await modelStore.initialize(); // to initialize database locally by getting synced
		}
	}

	render() {
        modelStore.data.forEach(item => console.log(item)); // access all the data in store
		modelStore.countUnuploadeds(); // to show number of unoploaded/synced items
		modelStore.dataMeta.tsUpload; // to show last timestamp uploaded/synced
		await modelStore.addItem({
          someField: 'someValue',
          anotherField: 'anotherValue',
        });
		await modelStore.deleteItem();
		await modelStore.upload(); // to upload/sync database local-remote
	}

	componentDidMount() {
		this.unsubTodos = modelStore.subscribe(this.rerender); // set callback when there is a change in store's data
	}

	componentWillUnmount() {
		this.unsubTodos();
		await modelStore.deinitialize(); // to destroy database locally if it's needed
	}

	rerender = () => {
        this.setState({
          _rerender: new Date(),
        });
    }
}
