To this end, many packages will include things like Unit Tests and documentation. This way I can run the unit Tests on my own to validate the package first. This is all fine and good, except when I don’t want them. There are times when I know the package well enough, or have used it enough, to not have to bother with any of that.5: Optimize your autoloadRegardless of whether you --prefer-dist or --prefer-source, when your package is incorporated into your project with require, it just adds it to the end of your autoloader. This isn’t always the best solution. Therefore Composer gives us the option to optimize the autoloader with the --optimize switch. Optimizing your autoloader converts your entire autoloader into classmaps. Instead of the autoloader having to use file_exists() to locate a file, Composer creates an array of file locations for each class. This can speed up your application by as much as 30%.$ composer dump-autoload --optimize$ composer require monolog/monolog:~1.18.0 -o
dompdf package for generating the PDF file. barryvdh/laravel-dompdf using composer package and thereafter we will add new route url with controller. Then we will create a blade file. Then after we have to just run project with serve and we can check the PDF file is for download. dompdf. To get started, we need to download fresh Laravel 5.7 application using command, so open our terminal and run the below command in the command prompt: composer create-project --prefer-dist laravel/laravel blog
composer require barryvdh/laravel-dompdf
