Summary

This chapter may not have been very exciting visually, but it did teach the following two elements that will underpin most apps:

• Local storage

• HTTP requests

By using HTTP requests you can interface to web servers and from there get and post data to and from your phone. It's your connection to the Internet! Conversely, by using local storage you can store content locally for those times when your phone is offline. These are really useful components of an app that you will use time and time again.

The next chapter moves on from the traditional method of local storage to the new kid in town, the cloud. We will look into how we can interface apps to cloud-based services and look closely at the cloud offering from Appcelerator.
