Here’s a simple solution to install basic authentication system with AngularJs.

This is a subject that is not much developed. Probably because of the different authentication methods and functional needs.

For me I needed:
– Authentication Required
– To authenticate the user on my RESTful API
– Not to send the user name and password to each request
– Not to make cross-domain
– To have a persistent connection (F5 or close browser window)
– To block access to the application if the authentication server is lost

// Logout current user
Route::get('/logout', function(){
    Auth::logout();

// Check state of current user authentification
Route::get('/guest', function(){
    if(Auth::guest()){
        throw new \Symfony\Component\HttpKernel\Exception\UnauthorizedHttpException('x-Basic')
