We've already used the Dog API to get the image of a single, completely random dog. However, today we're doing something a little different. Today, we are creating a full-fledged app to fulfill all of your pet-image-searching desires: both cats and dogs.

Use the Cat API for you cat-fetching needs.

This app, naturally, will have routes.

For the most part we have been centralizing state (usually in App) and passing it down to child components via props. That's good! However, this app is a little different.

We are making the conscious decision that we don't want to centralize state. Instead of one big app, our app is going to be more like a couple of tiny apps inside different routes.

These apps will be:

• Random dog image /dog/random - We've done this one before. Load a random dog image. Include a button that loads a new random image when clicked.

• Multiple random dogs /dog/random/:num - This will render the number of random dog images requested for in the num URL parameter. No button required.

• Random dog by breed /dog/:breed - This will render a dog image of the specified breed.

• Random cat image /cat/random. Load a random cat image. Include a button that loads a new random image when clicked.

• Multiple random cats /cat/random/:num - This will render the number of random cat images requested for in the num URL parameter. No button required.

• Random amounts of both cats and dogs /all/random. Load a random number(between 1 and 10) of cats AND dogs. (e.g 4 cats and 5 dogs).

These routes will each keep their own state. They don't have to interact with each other, because (theoretically) a user looking for a picture of a bulldog does not need to see a picture of a random dog.

If we are making this decision well in advance as a deliberate architectural move, it's fine to not have a centralized state. We should just keep in mind that, should we try to add more granular functionality after the fact, we may be in for a bad time.
