    {
        $role = Auth::user()->roles;

        switch($role){
            case 'codingTeam' : 
                return 'codingTeam';
            break;

            case 'admin' : 
                return 'home';

<?php

Route::get('/', function () {
    return view('login');
});

Route::group(['middleware' => ['auth']], function(){

Route::get('codingTeam','CodingTeamController@index')->name('codingTeam');

Route::get('/home', 'HomeController@index')->name('home');

Auth::routes();

Route::post('insert','Friends@insert');

Route::get('/logout', '\App\Http\Controllers\Auth\LoginController@logout');

Route::get('codingTeam','CodingTeamController@index')->name('codingTeam');

});
