如何托管 Fastify 应用

// Importing the Fastify module
import Fastify from 'fastify';
const fastify = Fastify({ logger: true });

// Defining a route handler for the '/' route
// This route handler sends 'Hello, World!' when accessed.
fastify.get('/', async (request, reply) => {
  return 'Hello World!';
});

// Making our Fastify application listen on port 80
fastify.listen({ port: 80 })
  .then((address) => {
    // This code block will be executed once the server is listening on port 80
    fastify.log.info(`Example app listening at ${address}`);
  })
  .catch((err) => {
    // This code block will be executed if there's an error trying to listen on port 80
    fastify.log.error(err);
    process.exit(1);
  });
