Authentication tutorial error: value must be an object, undefined handler

[hickeyadamc]

Hey!

The Authentication tutorial gives the error: Invalid server options 3000, value must be an object.

Copy pasted from tutorial:

var Bcrypt = require('bcrypt');
var Hapi = require('hapi');
var Basic = require('hapi-auth-basic');

var server = new Hapi.Server( 3000 );

var users = {
    john: {
        username: 'john',
        password: '$2a$10$iqJSHD.BGr0E2IxQwYgJmeP3NvhPrXAeLSaGCj6IR/XU5QtjVu5Tm',   // 'secret'
        name: 'John Doe',
        id: '2133d32a'
    }
};

var validate = function (username, password, callback) {
    var user = users[username];
    if (!user) {
        return callback(null, false);
    }

    Bcrypt.compare(password, user.password, function (err, isValid) {
        callback(err, isValid, { id: user.id, name: user.name });
    });
};

server.register(Basic, function (err) {
    server.auth.strategy('simple', 'basic', { validateFunc: validate });
    server.route({ method: 'GET', path: '/', config: { auth: 'simple' } });
});

That error can be fixed by changing:

var server = new Hapi.Server( );
server.connection({ port: 3000 });

Which results in a new error:

Fixed and deployed, sorry about that!

I am still getting this error:

I'll check it out and see what's going on, sorry for the premature close.

[hickeyadamc]

No problem! Thanks for the fast response!

Turns out the error was caused by lack of a handler. Also, a call to start might be helpful too. Here's what worked for me:

var Bcrypt = require('bcrypt');
var Hapi = require('hapi');
var Basic = require('hapi-auth-basic');

var server = new Hapi.Server();
server.connection({ port: 3000 });

var users = {
    john: {
        username: 'john',
        password: '$2a$10$iqJSHD.BGr0E2IxQwYgJmeP3NvhPrXAeLSaGCj6IR/XU5QtjVu5Tm',   // password is: 'secret'
        name: 'John Doe',
        id: '2133d32a'
    }
};

var validate = function (username, password, callback) {
    var user = users[username];
    if (!user) {
        return callback(null, false);
    }

    Bcrypt.compare(password, user.password, function (err, isValid) {
        callback(err, isValid, { id: user.id, name: user.name });
    });
};

server.register(Basic, function (err) {
    server.auth.strategy('simple', 'basic', { validateFunc: validate });
    server.route({
        method: 'GET',
        path: '/',
        handler: function (request, reply) {
              reply('Success!');
        },
        config: { auth: 'simple' } });
});
server.start(function () {
    console.log('Server running at:', server.info.uri);
});

Updated the tutorial again, this time fixed for real :)

[hickeyadamc]

Thanks! :)

server.register(require('inert'), (err) => {

if (err) {         throw err;     } 

server.route({         
	method: 'GET',         
	path: '/mydemo',         
	handler: function (request, reply) 
	{             
		reply.file('./public/mydemo.html');         
	}     
}); 

server.start((err) => { 

    if (err) {             
    	throw err;         
    }         
    server.log('info', 'Server running at: ' + server.info.uri);     
}); 

});

I am getting an error while using the inert@4 plugin in hapi@17 in the above code. Can some one please help me fix this? Following is the error I am able to see on cmd.
UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): AssertionError [ERR_ASSERTION]: Invalid register options "value" must be an object

Try switching to an async/await structure. This is what works for me:

async function startServer() {
  await server.register(require('inert'));
  server.route({
    method: 'GET',
    path: '/mydemo',
    handler: function(request, reply) {
      reply.file('./public/mydemo.html');
    }
  });

  await server.start();
});
startServer();

Check this issue for further details.
TLDR; v17 moved to an async/await approach, and away from callbacks, and the documentation is in process of being updated. Alternatively, you could downgrade to v16.
