Flash

Flash is a high-performance web framework for Java 21+, designed with implementation efficiency in mind. Unlike many popular server frameworks, initialization is performed ahead of time to minimize runtime overhead.

Routing is handled through a compressed trie (radix tree) for fast endpoint resolution. Request handling is multithreaded, with pooled handler instances that scale dynamically to improve concurrency and reduce memory allocation. Flash is entirely type-safe, zero-reflection and zero-dependency.

public class HelloWorld {
    private final int PORT = 8080;
    public static void main(String[] args) {
        FlashServer server = new FlashServer(PORT);

        //Defines a simple GET route.
        server.get("/hello", (req, res) -> "Hello, World!");

        server.start();
    }
}
