A service provider for Slim Framework that enables transient flash messages persisting across requests.
Slim-Flash is a service provider for the Slim Framework that adds flash messaging capabilities to PHP web applications. It allows developers to define transient messages that persist only from the current request to the next, which is essential for user notifications like success alerts or form errors.
PHP developers building web applications with the Slim Framework (versions 3 and 4) who need to implement user notifications that survive redirects, such as after form submissions.
Developers choose Slim-Flash for its lightweight, focused integration with Slim, following the framework's minimalist philosophy, and its straightforward API for managing session-based flash messages without unnecessary complexity.

Seamlessly works with Slim 3 and 4, including dependency injection containers like PHP-DI, as shown in the README examples for easy setup.
Supports strings, objects, or arrays for message storage, allowing complex data to be passed as flash messages, depending on session compatibility.
Messages are transient and automatically cleared after being accessed in the next request, preventing stale data without manual cleanup.
Uses PHP sessions to ensure messages survive redirects, which is essential for user notifications after form submissions or actions.
Requires custom middleware to start sessions and inject storage, as demonstrated in the README, adding complexity compared to Slim 3's simpler configuration.
Only supports PHP session storage by default, with no built-in alternatives for databases or other backends, restricting flexibility in distributed environments.
For Twig integration, an additional package like slim-twig-flash is needed, indicating it's not a complete out-of-the-box solution for view rendering.
