Russian-Doll Caching in Laravel
|
Popularized in the Rails world, Russian Doll caching is an interesting approach, where you create nested fragment caches for your view logic. If you then link the keys for each of these cached items to the model’s “updated at” timestamp, what you get is easy caching for your view logic, and automatic cachebusting whenever the model is updated.
In this series, we’ll build a custom package from scratch to offer this very functionality.
Overview and Homestead Setup
Let’s begin by learning what Russian Doll caching actually is, and then moving on to the initial project setup, where we install both Laravel and Homestead for the project.
We Need Something to Cache
Before we can starting building our caching system, we first need some sample data to cache. So let’s use this idea of an index card and notes. In this lesson, we’ll build up the necessary route, models, and migrations.
Russian Doll Caching
Now that we have all the setup out of the way, let’s write a custom Blade directive so that we may begin implementing our Russian Doll caching mechanism.
Create a Package
At this point, our experiment is working. However, for any new project, we’d have to copy all these files over. Gross. Let’s instead begin creating a reusable package, which we can then pull in through Composer.
Refactoring and Testing
Before we make this package available on Packagist.org, let’s do some refactoring and write some tests. As you’ll find, these tests might drive us toward a slightly different design. Let’s see!
How to Use Local Packages in Laravel
So far, we’ve been building our package in isolation. But, of course, we need to try this out within the context of an actual Laravel project. How exactly do we do that? Well, as it turns out, we can install local repositories with Composer quite easily. In this lesson, we’ll do our final tweaks in preparation for Packagist.org.
Registering With Packagist
The initial version of our package is ready to release. Naturally, there are a number of improvements we can make, but what we have so far is good enough for a 0.1.0 release. So let’s register our package with Packagist.org.
