How can you effectively debug and troubleshoot Laravel-based web applications?

2 Use Laravel Telescope

Laravel Telescope is a powerful debugging and monitoring tool that provides insights into your application's requests, exceptions, queries, jobs, events, mails, notifications, cache operations, and more. You can install Telescope as a composer package and access it via a web interface at /telescope. Telescope allows you to filter, search, and inspect various aspects of your application's performance and behavior, and identify potential problems or bottlenecks. You can also customize Telescope to suit your needs, by configuring its options, adding your own watchers, or integrating it with third-party services.

3 Use Laravel Log Viewer

Laravel Log Viewer is a simple and convenient package that lets you view and manage your application's log files from a web interface. You can install Log Viewer as a composer package and access it via a route of your choice. Log Viewer displays your log files in a table format, with columns for date, environment, level, message, and context. You can also filter the logs by level, date, or text, and download or delete them as needed. Log Viewer can help you quickly find and analyze errors, warnings, or notices in your application's logs, and take appropriate actions.

4 Use Laravel Debugbar

Laravel Debugbar is a useful package that adds a debug bar to the bottom of your web pages, showing information about your application's execution, such as queries, routes, views, session data, memory usage, and more. You can install Debugbar as a composer package and enable or disable it via a config file or a facade. Debugbar can help you check and optimize your application's performance and resource consumption, and spot any anomalies or inefficiencies. You can also extend Debugbar with your own collectors, or use existing ones for popular packages like Auth, Mail, or Laravel Nova.

5 Use Laravel Tinker

Laravel Tinker is a REPL (read-eval-print loop) tool that allows you to interact with your application's code and data from the command line. You can launch Tinker by running the php artisan tinker command, and then write and execute PHP code as if you were in your application's context. Tinker can help you test and debug your application's logic, models, functions, or configurations, without having to create a route or a controller. You can also use Tinker to manipulate your database, run migrations, seeders, or factories, or generate fake data.

6 Use Laravel Dusk

Laravel Dusk is a browser automation and testing tool that allows you to simulate user interactions and verify the output of your web pages. You can install Dusk as a composer package and use it to create and run tests using a fluent and expressive syntax. Dusk can help you debug and troubleshoot your application's front-end features, such as forms, buttons, links, menus, modals, or validations. You can also use Dusk to take screenshots, capture errors, or create custom assertions for your tests.
