|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
| Reminder about typical REST routes
| GET /posts            List posts
| GET /posts/create     Show a post creation form
| POST /posts           Create a post
| GET /posts/{id}       Show a post
| GET /posts/{id}/edit  Show a post update form
| PATCH /posts/{id}     Update a post
| DELETE /posts/{id}    Delete a post
