Laravel Tutorial
DAY 2
Route
URL Named Route
The route helper may be used to generate URLs to named routes.
Named routes allow you to generate URLs without being coupled to the actual URL defined on the route.
Therefore, if the route’s URL changes, no changes need to be made to your route function calls.
Routing - Group and Named Route
All Laravel routes are defined in your route files, which are located in the routes directory. For more information, click here.

Middleware
Middleware provide a convenient mechanism for filtering HTTP requests entering your application.
For example, Laravel includes a middleware that verifies the user of your application is authenticated. If the user is not authenticated, the middleware will redirect the user to the login screen.
Pagination
The paginate method automatically takes care of setting the proper limit and offset based on the current page being viewed by the user.
