In this chapter, we've taken the leap from simply showing content to showing content that's maintained in a sustainable and maintainable way using a database. While this allows us to display dynamic data easily, it's just a core step toward a fully-functional application.

We've looked at creating a database and then retrieving the data from it to inject into route while keeping our query parameters sanitized to prevent SQL injections.

We also accounted for potential bad requests with invalid GUIDs, by returning 404 Not Found statuses for any requested GUID that does not exist in our database. We also looked at requesting data by ID as well as the alphanumeric GUID.

This is just the start of our application, though.

In Chapter 4, Using Templates, we'll take the data that we've grabbed from MySQL (and Postgres) and apply some of Go's template language to them to give us more frontend flexibility.

By the end of that chapter, we will have an application that allows for creation and deletion of pages directly from our application.
