README

An application starter kit built on Slim 4, aimed at years of continued use—to keep building and maintaining real apps on the same stack.

• Slim handles HTTP routing and the request/response cycle.
• Deca layers familiar, low-dependency packages—PHP-DI, nyholm/psr7, Monolog, Twig, filp/whoops, and more—on top of Slim, with its own core code to wire them together cleanly.
• Interfaces (often PSR) abstract third-party boundaries so app code can survive library upgrades.
