In this chapter, we'll put together everything you learned so far. In recent years, the to-do app has replaced the blog as the canonical first app when learning a new platform. While a to-do app seems simple on the surface, it is complex enough to demonstrate most of the core features of a framework.

A to-do app built on Couchbase is well suited to demonstrate both the key/value and document features of Couchbase. With some minor feature additions to a typical to-do app, we'll be able to make use of some of the advanced view features available for Couchbase developers.

Throughout this chapter, we'll focus more on general design considerations rather than specific SDK or language constructs. As was the case in the previous chapters, we'll explore multiple SDKs as we build our to-do app. While the basic language constructs may vary from SDK to SDK, the broad strokes approach will not vary.
