Getting Started

1. Include the Header

Include the REXON.h file in your C++ project:

#include "REXON.h"

2. Create a Simple API

#include "REXON.h"

int main() {
    REXON::api server(8080);

    server.GET("/", [](std::string) {
        return REXON::Response("200 OK", "text/plain", "Welcome to REXON!");
    });

    server.POST("/data", [](std::string body) {
        return REXON::Response("200 OK", "application/json", "{\"received\":\"" + body + "\"}");
    });

    server.NOTFOUND([](std::string) {
        return REXON::Response("404 Not Found", "text/plain", "This route does not exist.");
    });

    server.show_log(true);
    server.start();
    return 0;
}
