Modern Features in a Legacy App via APIs
summary
Add modern features to a legacy PHP site by creating a second API-only Laravel app that implements cart, PayPal payments and notifications while leaving the legacy app mostly unchanged. The new app uses Laravel Sanctum token authentication, Guzzle HTTP client for requests, and returns Blade + Tailwind views compiled with Vite (HTML/JS injected into the legacy site) and a QR code the POS scans; demo shows an end-to-end order flow on PHP 8.3 and claims about 90% of the work being reusable for other frontends.
