Use Laravel Pipeline Use Webmozart Assert instead of assertion validations Use Laravel Collection Dont depend on whole Laravel and only depend on specific packages and versions for example, use Collection from Laravel 5.8 Augument Laravel facades using Laravel Macros Protected params are used all over the place. Use Value Objects instead or move away from using protected param and use public param instead or make the private Simplify codes. Someone should be able to read the code and understand what it does without having to read the comments. Take inspiration from Laravel codebase Move code to where it belongs. For example, if a method is used only in a specific class, move it to that class instead of having it in a helper file. Move related methods closer to each other Move stuff in the classes where they belong. Typehint everything. Use PHP 7.4 features Move away from docblocks as much as possible Use Attributes where possible Dont use our InvalidArgumentException, either use Webmozart Assert or use PHP's built-in \InvalidArgumentException Dont use any string, make intentions clear. Use Objects! Move away from using static methods. Use Dependency Injection instead Go through TODOs and FIXMEs and fix them Run Pest mutation, type coverage, test coverage, architectural tests, everything! Go over OOOAS and Laravel-OpenApi issues in their respective repos and solve all of them here! Make everything that can be readonly, readonly and everything that can be final, final Make it so easy that it just works! with 1 command or click! DHH/Laravel mantra. Make the doics easy and conversational with a point of view, like Ruby on Rails doc?
