💼 Career

Knowing how to enable and use debug mode is essential for Laravel developers to troubleshoot issues and ensure smooth application development.

1

Set APP_DEBUG to true in .env

Open the .env file and set the variable APP_DEBUG to true exactly like this: APP_DEBUG=true

Laravel

# Open .env file and set APP_DEBUG=true
# Your code here

Need a hint?

Find the line starting with APP_DEBUG= and change its value to true.

2

Create a variable $debug in config/app.php

In the config/app.php file, create a variable called $debug and set it to the value of env('APP_DEBUG', false) exactly like this: $debug = env('APP_DEBUG', false);

Laravel

APP_DEBUG=true

// Create $debug variable to read APP_DEBUG from environment
# Your code here

Need a hint?

Use the env helper to read APP_DEBUG and assign it to $debug.

3

Use $debug to conditionally show error details in a Blade view

In a Blade view file, use an @if directive with the variable $debug to show a message Debug mode is ON only when $debug is true. Write exactly: @if($debug) Debug mode is ON @endif

Laravel

APP_DEBUG=true

$debug = env('APP_DEBUG', false);

{{-- Show debug message if debug mode is on --}}
# Your code here

Need a hint?

Use Blade's @if directive to check $debug and show the message.

4

Complete Laravel debug mode setup to show detailed error pages

Ensure the APP_DEBUG variable is set to true in .env and the $debug variable is used in your app configuration and views so Laravel shows detailed error pages when errors happen.

Laravel

APP_DEBUG=true

$debug = env('APP_DEBUG', false);

@if($debug) Debug mode is ON @endif

// Finalize debug mode setup
# Your code here

Need a hint?

Make sure the environment and config use APP_DEBUG=true and your views check $debug to show debug info.
