On a freshly installed laravel 8  in the App Providers RouteServices php       The path to the  quot home quot  route for your application        This is used by Laravel authentication to redirect users after login         var string     public const HOME     home           The controller namespace for the application        When present  controller route declarations will automatically be prefixed with this namespace         var string null        protected  namespace    App  Http  Controllers    uncomment the protected  namespace    App Http Controllers   that should help you run laravel the old fashioned way  Incase you are upgrading from lower versions of laravel to 8 then you might have to implicitly add the protected  namespace    App Http Controllers   in the RouteServices php file for it to function the old way

If you would like to continue using the original auto-prefixed controller routing  you can simply set the value of the  namespace property within your RouteServiceProvider and update the route registrations within the boot method to use the  namespace property  class RouteServiceProvider extends ServiceProvider                  This namespace is applied to your controller routes                In addition  it is set as the URL generator s root namespace                 var string             protected  namespace    App Http Controllers                   Define your route model bindings  pattern filters  etc                 return void             public function boot                  this- gt configureRateLimiting              this- gt routes function                  Route  middleware  web                   - gt namespace  this- gt namespace                  - gt group base path  routes web php                  Route  prefix  api                   - gt middleware  api                   - gt namespace  this- gt namespace                  - gt group base path  routes api php

in laravel-8 default remove namespace prefix so you can set old way in laravel-7 like  in RouteServiceProvider php add this variable protected  namespace    App Http Controllers    and update boot method public function boot             this- gt configureRateLimiting             this- gt routes function                  Route  middleware  web                   - gt namespace  this- gt namespace                  - gt group base path  routes web php                  Route  prefix  api                   - gt middleware  api                   - gt namespace  this- gt namespace                  - gt group base path  routes api php

You are using Laravel 8  In a fresh install of Laravel 8  there is no namespace prefix being applied to your route groups that your routes are loaded into    quot In previous releases of Laravel  the RouteServiceProvider contained a  namespace property  This property s value would automatically be prefixed onto controller route definitions and calls to the action helper   URL  action method  In Laravel 8 x  this property is null by default  This means that no automatic namespace prefixing will be done by Laravel  quot  Laravel 8 x Docs - Release Notes  You would have to use the Fully Qualified Class Name for your Controllers when referring to them in your routes when not using the namespace prefixing  use App Http Controllers UserController   Route  get   users    UserController  class   index        or Route  get   users    App Http Controllers UserController index     If you prefer the old way  App Providers RouteServiceProvider  public function boot                  Route  prefix  api           - gt middleware  api           - gt namespace  App Http Controllers       lt ---------         - gt group base path  routes api php                 Do this for any route groups you want a declared namespace for  The  namespace property  Though there is a mention of a  namespace property to be set on your RouteServiceProvider in the Release notes and commented in your RouteServiceProvider this does not have any effect on your routes  It is currently only for adding a namespace prefix for generating URLs to actions  So you can set this variable  but it by itself won t add these namespace prefixes  you would still have to make sure you would be using this variable when adding the namespace to the route groups  This information is now in the Upgrade Guide Laravel 8 x Docs - Upgrade Guide - Routing With what the Upgrade Guide is showing the important part is that you are defining a namespace on your routes groups  Setting the  namespace variable by itself only helps in generating URLs to actions  Again  and I can t stress this enough  the important part is setting the namespace for the route groups  which they just happen to be doing by referencing the member variable  namespace directly in the example  Update  If you have installed a fresh copy of Laravel 8 since version 8 0 2 of laravel laravel you can uncomment the protected  namespace member variable in the RouteServiceProvider to go back to the old way  as the route groups are setup to use this member variable for the namespace for the groups     protected  namespace    App  Http  Controllers    The only reason uncommenting that would add the namespace prefix to the Controllers assigned to the routes is because the route groups are setup to use this variable as the namespace      - gt namespace  this- gt namespace

The Laravel 8 documentation actually answers this issue more succinctly and clearly than any of the answers here  Routing Namespace Updates In previous releases of Laravel  the RouteServiceProvider contained a  namespace property  This property s value would automatically be prefixed onto controller route definitions and calls to the action helper   URL  action method  In Laravel 8 x  this property is null by default  This means that no automatic namespace prefixing will be done by Laravel  Therefore  in new Laravel 8 x applications  controller route definitions should be defined using standard PHP callable syntax  use App Http Controllers UserController   Route  get   users    UserController  class   index      Calls to the action related methods should use the same callable syntax  action  UserController  class   index      return Redirect  action  UserController  class   index      If you prefer Laravel 7 x style controller route prefixing  you may simply add the  namespace property into your application s RouteServiceProvider   There s no explanation as to why Taylor Otwell added this maddening gotcha  but I presume he had his reasons

The way to define your routes in laravel 8 is either    Using PHP callable syntax    use App Http Controllers HomeController  Route  get       HomeController  class   index      OR    Using string syntax    Route  get       App Http Controllers HomeController index     A resource route becomes    Using PHP callable syntax    use App Http Controllers HomeController  Route  resource      HomeController  class    This means that in laravel 8  there is no automatic controller declaration prefixing by default  If you want to stick to the old way  then you need to add a namespace property in the app Providers RouteServiceProvider php and activate in the routes method  Follow this image instructions below

laravel 8 updated RouteServiceProvider and it affects route with string syntax  You can change it like above  but recommended way is using action syntax not using route with string syntax  Route  get  register    Api RegisterController register     Should be changed to  Route  get  register    RegisterController  class   register
