Hapi.js is a small Node framework for developing back end web apps.

In this article, we’ll look at how to create back end apps with Hapi.js.

Create a Plugin

We can create plugins and use them with Hapi.

For example, we can write:

index.js

const Hapi = require('@hapi/hapi');
const init = async () => {
  const server = Hapi.server({
    port: 3000,
    host: '0.0.0.0',
  });
  await server.register(require('./myPlugin'));
  server.route({
    path: '/',
    method: 'GET',
    handler(request, h) {      
      return h.response('hello')
    },
  });
  await server.start();  
  console.log('Server running on %s', server.info.uri);
};
process.on('unhandledRejection', (err) => {
  console.log(err);
  process.exit(1);
});
init();

myPlugin.js

const myPlugin = {
  name: 'myPlugin',
  version: '1.0.0',
  register: async function (server, options) {
    server.route({
        method: 'GET',
        path: '/test',
        handler: function (request, h) {
          return 'hello, world';
        }
    });
  }
};
module.exports = myPlugin
