HTTP method routing (GET, POST, PUT, DELETE) in Laravel

📖 Scenario: You are building a simple Laravel web application to manage a list of books. You want to set up routes that respond to different HTTP methods to handle viewing, adding, updating, and deleting books.

🎯 Goal: Create Laravel routes that handle GET, POST, PUT, and DELETE HTTP methods for a /books URL path.

📋 What You'll Learn

Create a route for GET /books that returns a list of books.

Create a route for POST /books that adds a new book.

Create a route for PUT /books/{id} that updates a book by its ID.

Create a route for DELETE /books/{id} that deletes a book by its ID.

💡 Why This Matters

🌍 Real World

Web applications often need to handle different HTTP methods to perform actions like viewing, creating, updating, and deleting data.

💼 Career

Understanding HTTP method routing is essential for backend developers working with Laravel or similar frameworks to build RESTful APIs and web apps.

1

Create a GET route for listing books

In the routes/web.php file, create a GET route for the path /books that returns the string 'List of books'.

Laravel

# Your code here

Need a hint?

Use Route::get('/books', function () { ... }); to define the GET route.

2

Add a POST route for adding a new book

Below the GET route, add a POST route for the path /books that returns the string 'Add a new book'.

Laravel

<?php

use Illuminate\Support\Facades\Route;

Route::get('/books', function () {
    return 'List of books';
});

# Your code here

Need a hint?

Use Route::post('/books', function () { ... }); to define the POST route.

3

Add a PUT route for updating a book by ID

Add a PUT route for the path /books/{id} that returns the string 'Update book with id: ' . $id. Use the variable $id in the route closure parameter.

Laravel

<?php

use Illuminate\Support\Facades\Route;

Route::get('/books', function () {
    return 'List of books';
});

Route::post('/books', function () {
    return 'Add a new book';
});

# Your code here

Need a hint?

Use Route::put('/books/{id}', function ($id) { ... }); to define the PUT route with a parameter.

4

Add a DELETE route for deleting a book by ID

Add a DELETE route for the path /books/{id} that returns the string 'Delete book with id: ' . $id. Use the variable $id in the route closure parameter.

Laravel

<?php

use Illuminate\Support\Facades\Route;

Route::get('/books', function () {
    return 'List of books';
});

Route::post('/books', function () {
    return 'Add a new book';
});

Route::put('/books/{id}', function ($id) {
    return 'Update book with id: ' . $id;
});

# Your code here

Need a hint?

Use Route::delete('/books/{id}', function ($id) { ... }); to define the DELETE route with a parameter.
