hapi-auth-cookie failing to load session strategy - node.js

Question

There's not many examples out there for hapi and its auth-cookie plugin but here's what I have so far in an attempt to secure a route. Note, most of the examples I've seen are using an older version of hapi which doesn't seem to quite apply to this situation and im hoping im just missing something simple:
var Hapi = require('hapi');
var Mongoose = require('mongoose');
Mongoose.connect('mongodb://localhost/rfmproducetogo');
var server = new Hapi.Server(8080, "localhost");
server.pack.register([{
plugin: require("lout")
}, {
plugin: require('hapi-auth-cookie')
}, {
plugin: require("./plugins/togo")
}, {
plugin: require("./plugins/auth")
}], function(err) {
if (err) throw err;
server.auth.strategy('session', 'cookie', {
password: 'shhasecret',
cookie: 'wtfisthisfor',
isSecure: false,
redirectTo: false
});
server.start(function() {
console.log("hapi server started # " + server.info.uri);
});
});
And in my togo plugin I have this route setup to use the session
exports.create = function(plugin) {
plugin.route({
method: 'POST',
path: '/togo/add',
handler: function(request, reply) {
produce = new Produce();
produce.label = request.payload.label;
produce.price = request.payload.price;
produce.uom = request.payload.uom;
produce.category = request.payload.category;
produce.save(function(err) {
if (!err) {
reply(produce).created('/togo/' + produce._id);
} else {
reply(err);
}
});
},
config: {
auth: 'session'
}
});
};
The error im seeing is this:
/home/adam/Projects/bushhog/node_modules/hapi/node_modules/hoek/lib/index.js:421
throw new Error(msgs.join(' ') || 'Unknown error');
^

Answer 1

this issue occurs when you try to use an authentication strategy before it's actually available.
You're already following a good application setup by splitting the functionality into individual, small plugins with a given scope.
UPDATE: here's a dedicated tutorial for that problem, how to fix „unknown authentication strategy“
A good way to set up authentication and your plugins that rely on authentication is to create an extra "auth plugin" that adds your desired strategies and can be used as a dependency in your other plugins.
hapi auth plugin example
exports.register = function (server, options, next) {
// declare/register dependencies
server.register(require('hapi-auth-cookie'), err => {
/**
* Register authentication strategies to hapi server
*
* We’re using hapi-auth-cookie plugin to store user information on
* client side to remember user data on every website visit
*
* For sure, we could and will add more authentication strategies.
* What’s next: JWT (we highly welcome pull requests to add JWT functionality!)
*/
server.auth.strategy('session', 'cookie', {
password: 'ThisIsASecretPasswordThisIsASecretPassword',
cookie: 'hapi-rethink-dash',
redirectTo: '/login',
isSecure: false
});
server.log('info', 'Plugin registered: cookie authentication with strategy »session«')
next()
})
}
exports.register.attributes = {
name: 'authentication',
version: '1.0.0'
}
In your /plugins/togo you set the authentication plugin as a dependency (with server.dependency([array-of-deps])) which means hapi registers the auth plugin first and the depending ones afterwards.
You register your plugins like this:
server.register([{
plugin: require('./plugins/authentication')
}, {
plugin: require("./plugins/togo")
}], function(err) {
// handle callback
})
Check hapi-rethinkdb-dash for a detailed example.
Hope that helps!

Answer 2

keep in mind if you use server.dependency inside a plugin like Marcus Poehls did, you also need to register that dependency
server.register([{
plugin: require('hapi-auth-cookie')
},{
plugin: require('./plugins/authentication')
}, {
plugin: require("./plugins/togo")
}], function(err) {
// handle callback
})
