    One should be careful while developing any application with the number of SQL queries triggered for each request. Here we’re talking about analysing SQL queries for your Laravel application.

    Laravel Debugbar for the rescue

    Laravel Debugbar is an open-source package built to integrate PHP Debug bar with your Laravel application & keep track of all your SQL queries, so that you can analyse and optimise your code accordingly.

    It will give you the nice popup toolbar just like the chrome developer tools.

    Installation

    Right into your project root, install the package using composer.

    composer require barryvdh/laravel-debugbar

    Adding the Service Provider

    This package is only required for Development, so instead of adding the ServiceProvider in config/app.php, we’ll do add this in app/Providers/AppServiceProvider.php instead.

    Right into the register method,

    public function register() {
          if ( $this->app->isLocal() ) {
             $this->app->register( \Barryvdh\Debugbar\ServiceProvider::class );
          }
       }
    }

    Now if you head back to your browser, you may see a nice little popup listing your SQL queries.

    Conclusion

    Its always a good practice to keep track of your SQL queries to avoid n+1 trap where multiple queries are running for a simple thing.
