💼 Career

Understanding routing is essential for backend web developers working with Laravel or similar frameworks.

1

Create the home page route

In the routes/web.php file, create a route for the URL '/' that returns the text 'Welcome to the home page'. Use Route::get with a closure function.

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Create a route for '/' that returns 'Welcome to the home page'
// Your code here

Need a hint?

Use Route::get('/', function () { return 'text'; }); to create a simple route.

2

Add an about page route

Add a new route in routes/web.php for the URL '/about' that returns the text 'About us page'. Use Route::get with a closure function.

Laravel

<?php

use Illuminate\Support\Facades\Route;

Route::get('/', function () {
    return 'Welcome to the home page';
});

// Add a route for '/about' that returns 'About us page'
// Your code here

Need a hint?

Follow the same pattern as the home page route but change the URL and returned text.

3

Explain how routing maps URLs to logic

Add a comment above the routes in routes/web.php explaining that Laravel uses routes to connect URLs to the code that runs when those URLs are visited.

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Explain how Laravel routing connects URLs to code
// Your code here

Route::get('/', function () {
    return 'Welcome to the home page';
});

Route::get('/about', function () {
    return 'About us page';
});

Need a hint?

Write a simple comment explaining the purpose of routes in Laravel.

4

Add a route for contact page

Add a route in routes/web.php for the URL '/contact' that returns the text 'Contact us page'. This completes the basic routing setup.

Laravel

<?php

use Illuminate\Support\Facades\Route;

// Laravel routing maps URLs to specific code logic that runs when a user visits that URL.
// This lets the app show different pages or responses based on the URL.

Route::get('/', function () {
    return 'Welcome to the home page';
});

Route::get('/about', function () {
    return 'About us page';
});

// Add a route for '/contact' that returns 'Contact us page'
// Your code here

Need a hint?

Use the same route pattern to add the contact page.
