Public interface
The final piece of our web service is the public interface that will allow a client app to request the listing data. Since the Vuebnb listing page is designed to display one listing at a time, we'll at least need an endpoint to retrieve a single listing.
Let's now create a route that will match any incoming GET requests to the URI /api/listing/{listing} where {listing} is an ID. We'll put this in the routes/api.php file, where routes are automatically given the /api/ prefix and have middleware optimized for use in a web service by default.
We'll use a closure function to handle the route. The function will have a $listing argument, which we'll type hint as an instance of the Listing class, that is, our model. Laravel's service container will resolve this as an instance with the ID matching {listing}.
We can then encode the model as JSON and return it as a response.
routes/api.php:
<?php
use App\Listing;
Route::get('listing/{listing}', function(Listing $listing) {
return...
