Congratulations! We're all done! We now have a fully featured URL shortener that does everything we need plus some cool extras.
In this episode, we will look into the new health check endpoint that will come by default in a Rails 7.1 application.
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.
In this lesson, we will look at a new option coming to ActiveJob in Rails 7.1 for enqueuing multiple jobs at once using the perform_all_later class method.
Anyone can add, edit, and delete any Link in our URL Shortener database. Your challenge is to add users, associate links with them and only allow editing of your own links.
