In this episode, we dig into a super common issue in web apps: loading a ton of related data, like posts with their authors, and ending up accidentally hammering your database with way too many queries. You'll see how, by looping over posts on a page and pulling in each user's info one at a time, we end up with a database query for every single post—definitely not ideal!
To fix this, we take a look at how Laravel's Eloquent ORM handles relationships and the concept of eager loading. You'll learn how just a tiny tweak—adding the with
method when querying for posts—can take us from hundreds of queries down to just two: one for the posts and one for all their related users. That's a huge speed win, and it keeps our database and server happy.
We also touch on how you can eager load additional relationships, like topics, all using the same method. While things might get a bit more complex with deeper relationships (which we’ll cover later), this episode is all about laying the foundation and giving you an easy performance boost right away.
If you're curious about how to make sure you never forget to eager load the right stuff, stay tuned—next episode is all about that trick!
