Congratulations! We're all done! We now have a fully featured URL shortener that does everything we need plus some cool extras.
Once our application has lots of links, it will become impossible to use. Let's add pagination to make our application usable once we have hundreds or thousands of links.
Now that we've got a thorough test suite, we want to make sure tests are run anytime we push code to GitHub. We can setup GitHub Actions to test our code and automatically deploy it when tests pass.
Testing our URL shortener is very important now that we've implemented edit permissions on Links. We want to make sure everything works as expected for each type of user.
Here's how we'd add Users and handle edit permissions for links. See how it compares to your implementation and consider the pros/cons of each approach.
