Start server without callback fails

[felansu]

When starts the server without callback as it described at example on home page

Code example

var Hapi = require('hapi');

// Create a server with a host and port
var server = new Hapi.Server();
server.connection({ 
    host: 'localhost', 
    port: 8000 
});

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

// Start the server
server.start();

Exception

/home/felansu/Projects/QRBWEB/node_modules/hapi/lib/server.js:242
        return callback();
               ^
TypeError: undefined is not a function

This is a new requirement in hapi 9. See release notes here: #2682

[felansu]

I've seen the message: "Require callback for server.start() and server.stop()."

Then I think the problem is that the code example on the hapi homepage is wrong. Also as it is required hapi could throw a better message validating whether callback is defined.

Thanks

The site is fixed code wise but it looks like it needs to be redeployed again.

This is a hapijs.com issue not hapi specifically. I have linked the issue here for reference. Please close this. I have issued a PR for review.

+1 for felansu comment. Better error message would be great on this.
