Refactoring to SOLID in Laravel
summary
Refactors a monolithic Livewire mortgage component into separate Blade pieces and plain PHP services, moving calculations and quoting out of the UI and into tested units. Extracts a calculate LTV service, a get product quotes service and a create product quote DTO, replaces DB-heavy tests with unit tests, uses Livewire events between form and search, and resolves flaky cases around LTV values like 75 80 and 79. Code is available on GitHub filmed at Laracon EU Amsterdam April 26 2022.
