In this episode, we're tackling a pretty important optimization: caching translations. Right now, every time our app needs to translate something, it reads the translation files from disk. That might not seem like a big deal with just a few files, but as your app grows, this can slow things down a lot.
So, what do we do? We walk through setting up a simple cache for our translations. We'll use Laravel's cache
helper (with your choice of backend: file, Redis, etc.), and we'll show you how to store the translations "forever" (or for as long as you want). That way, we're not constantly reading from files—which makes everything snappier.
You'll see us handling things like cache keys—making sure to include the current locale so German, English, and any other language get their own set of translations. And we show you what happens if you don't do that, just so you can see why it's necessary!
We'll also quickly cover how to clear the cache if you add more translations while developing, so you don't get stuck seeing old language data. By the end, your translations will be blazing fast, with just a bit of code change.
