Adding Routes to Hapi js server

Check out my previous blog to set up the Hapi js server.

Now, we’ll add route to our index.js file.

server.route({
        method: 'GET',
        path: '/',
        handler: (request, h) => {

            return 'Hello World!';
        }
    });

Here, the method can be GET, POST, PUT, DELETE, as per the requirement of the task. Handler function will execute on going to the specified path. This functions should always return a value, which can be any result, error or null.

The index.js file will now look like below.

'use strict';
const Hapi = require('@hapi/hapi');
const init = async () => {
        const server = Hapi.server({
              port: 8000,
              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);
     };
});
init();

Now, run the file using below command on the terminal

node index.js

You’ll see the terminal showing

Server running at: http://localhost:8000

Now, go to your browser and type the path you want to execute. Here, our path will be http://localhost:8000/

You’ll see the below screen.

This is the expected output. Likewise, we can execute different requests for performing specific tasks for any application.
