import {
    HttpRouter,
    HttpRes,
    defaultHttpRouterAdapter,
} from "@daiso-tech/core/http-router";
import { serve } from "@hono/node-server";

const router = new HttpRouter({ router: defaultHttpRouterAdapter });

router.endpoint({
    url: "/hello",
    method: "GET",
    handler: async () => HttpRes.text("Hello Node.js!"),
});

const server = serve({
    fetch: (request: Request) => router.fetch(request),
    port: 3000,
});

// Graceful shutdown
process.on("SIGINT", () => {
    server.close();
    process.exit(0);
});
process.on("SIGTERM", () => {
    server.close(() => process.exit(0));
});
