Routing

This code demonstrates how to set up a basic HTTP server with a single route using @hapi/hapi. The server listens on port 3000 and responds with 'Hello, world!' when the root URL is accessed.

const Hapi = require('@hapi/hapi');

const init = async () => {
  const server = Hapi.server({
    port: 3000,
    host: 'localhost'
  });

  server.route({
    method: 'GET',
    path: '/',
    handler: (request, h) => {
      return 'Hello, world!';
    }
  });

  await server.start();
  console.log('Server running on %s', server.info.uri);
};

process.on('unhandledRejection', (err) => {
  console.log(err);
  process.exit(1);
});

init();

Plugins

This code demonstrates how to create and register a plugin in @hapi/hapi. The plugin adds a new route '/plugin' that responds with 'Hello from plugin!'.

const Hapi = require('@hapi/hapi');

const init = async () => {
  const server = Hapi.server({
    port: 3000,
    host: 'localhost'
  });

  const plugin = {
    name: 'myPlugin',
    version: '1.0.0',
    register: async function (server, options) {
      server.route({
        method: 'GET',
        path: '/plugin',
        handler: (request, h) => {
          return 'Hello from plugin!';
        }
      });
    }
  };

  await server.register(plugin);
  await server.start();
  console.log('Server running on %s', server.info.uri);
};

process.on('unhandledRejection', (err) => {
  console.log(err);
  process.exit(1);
});

init();

Validation

This code demonstrates how to use Joi for payload validation in @hapi/hapi. The route '/data' expects a POST request with a payload containing a 'name' and 'age' field, both of which are validated according to the specified rules.

const Hapi = require('@hapi/hapi');
const Joi = require('joi');

const init = async () => {
  const server = Hapi.server({
    port: 3000,
    host: 'localhost'
  });

  server.route({
    method: 'POST',
    path: '/data',
    options: {
      validate: {
        payload: Joi.object({
          name: Joi.string().min(3).max(30).required(),
          age: Joi.number().integer().min(0).required()
        })
      }
    },
    handler: (request, h) => {
      return `Hello, ${request.payload.name}!`;
    }
  });

  await server.start();
  console.log('Server running on %s', server.info.uri);
};

process.on('unhandledRejection', (err) => {
  console.log(err);
  process.exit(1);
});

init();
