I am pretty new to Laravel 4 and Composer. While I do Laravel 4 tutorials, I couldn't understand the difference between those two commands; php artisan dump-autoload and composer dump-autoload What's the difference between them?
Laravel's Autoload is a bit different:
1) It will in fact use Composer for some stuff
2) It will call Composer with the optimize flag
3) It will 'recompile' loads of files creating the huge bootstrap/compiled.php
4) And also will find all of your Workbench packages and composer dump-autoload them, one by one.
php artisan dump-autoload was deprecated on Laravel 5, so you need to use composer dump-autoload
composer dump-autoload
PATH vendor/composer/autoload_classmap.php
- Composer dump-autoload won’t download a thing.
- It just regenerates the list of all classes that need to be included in the project (autoload_classmap.php).
- Ideal for when you have a new class inside your project.
- autoload_classmap.php also includes the providers in config/app.php
php artisan dump-autoload
- It will call Composer with the optimize flag
- It will 'recompile' loads of files creating the huge bootstrap/compiled.php
