Step 1: Initial App Without DataLocate this document in the navigation structure

We start with a simple app scenario with a list of items bound to an OData service. Since the OData service is not available yet on a real server, we will use the mock server to simulate both data and data calls.

For this very simple tutorial app we will use an OData service called NerdMeetups that lists meet-up groups according to location, date, topic, etc. The app will display a simple list populated by a function import call to display only upcoming meet-ups (meet-ups with an event date greater to the current date).

Additionally, a button will fetch the first three meet-ups (using a custom URL parameter called first). This exercise simply shows an app with no data retrieved from the back end. This can happen when the back end is down, or when the service is not implemented yet.

Usually you start the development of an app with local mock data first. This way you can continue implementing the application logic without depending on the back end readiness and connectivity.

To set up your project for this tutorial, download the files for Step 1 from the Explored app in the Demo Kit under Mock Server - Step 1. Copy the code to your workspace and make sure that the application runs by calling the webapp/test/mockServer.html file.

Depending on your development environment you might have to adjust resource paths and configuration entries. The project structure and the files coming with this tutorial are explained in detail in the Walkthrough tutorial.

You should have the same files as displayed in the following figure:
