A very common type of application you might build is one that uses a tab-based navigation system. This design pattern works very well when you have a limited number (five or fewer) of groups (or tabs) of content. We are going to use this design pattern to create an app that will allow you to explore the various United States National Parks (in honor of them celebrating their centennial in 2016). Figure 8-1 shows what our final app will look like.
We are again going to use the Ionic CLI to scaffold our application. First, create a new directory that we will be building from. I named my directory IonicParks:
$ ionic start IonicParks
Since we are going to be creating a tabs-based app, we did not need to pass in a template name, since the tab template is the default.
Next, change your working directory to the newly created IonicParks directory:
$ cd IonicParks
Now let’s explore the template itself (Figure 8-2) before we get down to business:
$ ionic serve
Not a lot here, but we can navigate between the three tabs (named Home, About, and Contact), and see the content change.
Taking a look inside the app.module.ts file, we see that instead of importing one page, ...
