Creating Laravel packages enables code reusability across projects. I structure packages with src/ for code, config/ for configuration, and database/ for migrations. Service providers register package components—routes, views, commands, configs. The publishes() method lets users customize assets. Auto-discovery automatically registers providers in Laravel 5.5+. Packages define dependencies in composer.json. I test packages independently with Orchestra Testbench. The loadRoutesFrom(), loadViewsFrom(), and loadMigrationsFrom() methods integrate package resources. For distribution, I publish to Packagist. Package development promotes modularity and open-source contribution.
