Technical requirements

The complete code for all the exercises and the activity in this chapter is available on GitHub at https://packt.link/9MVrd.

In this chapter, we will build an example app where we will assume that Secret Cat Agents (SCAs) get deployed in a record time of 15 seconds. When a cat successfully deploys, we will notify the user and let them launch the app, presenting them with a successful deployment message.

We will go with 15 seconds because that way, we will avoid having to wait for very long before our background task completes.
