Laravel Installation

Open terminal and run this command to create a laravel project.

composer create-project laravel/laravel myblog

It will create a project folder with name myblog inside your local system.

To start the development server of laravel –

php artisan serve

URL: http://127.0.0.1:8000

Assuming laravel already installed inside your system.

Laravel 9 Error Pages

There are several status codes which has been used for errors. According to their error code respective error pages by default available in laravel 9 application.

Error Pages are –

401.blade.php
403.blade.php
404.blade.php
419.blade.php
429.blade.php
500.blade.php
503.blade.php

These all error pages stored inside /errors folder. The error layout you see in your screen for laravel application comes from these files. By default /errors folder will not be available inside /resources/views folder.

Publish Error Pages

Open project into terminal and run this command to publish error pages.

$ php artisan vendor:publish --tag=laravel-errors

Above command will create /resources/views/errors folder and you will see all error pages now available to work with.

Default 404 Error Page

Let’s say a laravel application contains these routes.

web.php

//...

Route::get("/", function () {
    echo "<h3>Welcome to home page</h3>";
});

Route::get("/about-us", function () {
    echo "<h3>Welcome to about us page</h3>";
});

When we open URL like

http://127.0.0.1:8000/ OR http://127.0.0.1:8000/about-us It will work.
http://127.0.0.1:8000/contact-us – It will throw 404 error and open a default 404 error page of laravel.

Output be like –

Next, let’s change this default layout for laravel 404 page.
