TypeError: server.connection is not a function in Hapi nodejs

Question

I started working with Hapi nodejs framework. I am using "[email protected]" and here is my code in server.js to initiate application.

'use strict';

const Hapi = require('hapi');

const server = new Hapi.Server();
server.connection({ port: 3000, host: 'localhost' });

server.route({
    method: 'GET',
    path: '/',
    handler: function (request, reply) {
        reply('Hello, world!');
    }
});

server.start((err) => {

    if (err) {
        throw err;
    }
    console.log(`Server running at: ${server.info.uri}`);
});

After running my project with node server.js from terminal it's throwing error as given below.

/var/www/html/hello_hapi/server.js:6
server.connection({ port: 3000, host: 'localhost' });
       ^

Answer 1

I found a solution to resolve my error. I just replaced
server.connection({ port: 3000, host: 'localhost' });
with
const server = new Hapi.Server({ port: 3000, host: 'localhost' });

Here is the description below: According to hapi v17.0.0 they Removed support for multiple connections for a single server

1. The server.connection() method is replaced with options passed directly when creating a server object.
2. connection property is removed from all objects.
3. All connection methods moved to the server.
4. Removed support for labels and select() methods and options.

Answer 2

In hapi 16, there was support for server.connection(), but in hapi 17, they replaced server.connection() and instead

const Hapi = require('hapi')
const server = Hapi.server({
port:3000 || process.env.port
})

This can be used in node js.

If you are using typescript and typings, then

const server = new Hapi.server({port:3000 || process.env.port})

Answer 3

replace with this

const server = new Hapi.Server({  
  host: 'localhost',
  port: 3000
})

if you are using this

server.connection({   

    port: 8000,
    host: 'localhost'

});
