There are multiple good ways to pass data from Laravel to Vue. In a new blogpost Jesse Schutt covers all the options.
It has been helpful to think of my application as "layers" or separate sections of code each with varying responsibilities. I like to think of Laravel as the intermediary between the persistent data in the database, and the Vue components comprising the front-end of the app. Though the boundaries between Laravel and Vue may appear unclear at the outset, the only way one can know about the other's data is if it is explicitly passed. Blade templates implicitly know a lot about the application, but Vue operates on a different layer, so it only knows what we tell it. Fortunately, there are a number of ways to provide Vue with the data it needs.
