Localisation is a breeze in Laravel applications, but what happens when you need to bring this to the client-side? Turns out in Inertia, it's pretty simple. In this course, we'll build a language switcher, share translations with the client, and build a simple translation helper for Vue to use directly in templates. We'll also cover caching translations to keep things running smoothly. The best part? With the magic of reactivity, we'll be able to switch languages without any page refresh, and see everything instantly translated.
