What is the URL prefix for routes inside this group?

Consider this Laravel route group:

Route::prefix('admin')->group(function () {
    Route::get('/dashboard', function () {
        return 'Admin Dashboard';
    });
});

What URL path will you visit to see the 'Admin Dashboard'?

Laravel

Route::prefix('admin')->group(function () {
    Route::get('/dashboard', function () {
        return 'Admin Dashboard';
    });
});

A /admin/dashboard

B /dashboard/admin

C /admin

D /dashboard

💡 Hint

Think about how the prefix adds to the route path.

The prefix 'admin' is added before all routes inside the group, so the full URL becomes '/admin/dashboard'.

Which option correctly applies middleware to a route group?

You want to apply the 'auth' middleware to all routes inside a group. Which code snippet is correct?

A

Route::group(['middleware' => 'auth'], function () {
    Route::get('/profile', function () {
        return 'Profile';
    });
});

B

Route::group('middleware' => 'auth', function () {
    Route::get('/profile', function () {
        return 'Profile';
    });
});

C

Route::middleware('auth')->group(function () {
    Route::get('/profile', function () {
        return 'Profile';
    });
});

D

Route::middleware(['auth'])->group(function () {
    Route::get('/profile', function () {
        return 'Profile';
    });
});

💡 Hint

Check the correct syntax for passing middleware in a group.

The correct syntax for applying middleware in a group can use either an array as the first argument to Route::group(), or the middleware() method before group().

What is the output of this nested route group?

Given this Laravel route group code:

Route::prefix('api')->group(function () {
    Route::prefix('v1')->group(function () {
        Route::get('/users', function () {
            return 'Users v1';
        });
    });
});

What URL path will return 'Users v1'?

Laravel

Route::prefix('api')->group(function () {
    Route::prefix('v1')->group(function () {
        Route::get('/users', function () {
            return 'Users v1';
        });
    });
});

A /users/api/v1

B /v1/api/users

C /api/users/v1

D /api/v1/users

💡 Hint

Prefixes stack in the order they are nested.

The outer prefix 'api' and inner prefix 'v1' combine to form '/api/v1/users'.

Why does this route group cause a syntax error?

Look at this code:

Route::group(['prefix' => 'admin', 'middleware' => 'auth'], function () {
    Route::get('/dashboard', function () {
        return 'Dashboard';
    });
});

Why does this code cause a syntax error?

Laravel

Route::group(['prefix' => 'admin', 'middleware' => 'auth'], function () {
    Route::get('/dashboard', function () {
        return 'Dashboard';
    });
});

A The callback function is missing the use keyword to import variables.

B The function keyword is missing parentheses after it.

C The array syntax is correct; no syntax error here.

D The array keys should be strings without quotes.

💡 Hint

Check the array syntax and function declaration carefully.

The array syntax and function declaration are correct; this code does not cause a syntax error.

How does the 'as' option affect route names in groups?

Consider this route group:

Route::name('admin.')->group(function () {
    Route::get('/users', function () {
        return 'Users';
    })->name('users');
});

What is the full route name for the '/users' route?

Laravel

Route::name('admin.')->group(function () {
    Route::get('/users', function () {
        return 'Users';
    })->name('users');
});

A users

B admin.users

C adminusers

D admin.users.users

💡 Hint

The 'name' prefix adds before the route's own name.

The 'name' method on the group adds 'admin.' before each route's name, so the full name is 'admin.users'.
