everyauth
==========

Authentication and authorization (password, facebook, & more) for your node.js Connect and Express apps.

There is a NodeTuts screencast of everyauth here

There is also a Google Groups (recently created)
here to post questions and discuss
potential ideas and extensions to the library.

So far, everyauth enables you to login via:

everyauth is:

- Modular - We have you covered with Facebook and Twitter
OAuth logins, basic login/password support, and modules
coming soon for beta invitation support and more.
- Easily Configurable - everyauth was built with powerful
configuration needs in mind. Configure an authorization strategy
in a straightforward, easy-to-read & easy-to-write approach,
with as much granularity as you want over the steps and
logic of your authorization strategy.
- Idiomatic - The syntax for configuring and extending your authorization strategies are
idiomatic and chainable.

Installation

$ npm install everyauth

Quick Start

Using everyauth comes down to just 2 simple steps if using Connect
or 3 simple steps if using Express:

1. Choose and Configure Auth Strategies - Find the authentication strategy
you desire in one of the sections below. Follow the configuration
instructions.
2. Add the Middleware to Connect

``javascript
var everyauth = require('everyauth');
// Step 1 code goes here

// Step 2 code
var connect = require('connect');
var app = connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'mr ripley'})
, everyauth.middleware()
, connect.router(routes)
);
`
3. Add View Helpers to Express

`javascript
// Step 1 code
// ...
// Step 2 code
// ...

// Step 3 code
everyauth.helpExpress(app);

app.listen(3000);
`

For more about what view helpers everyauth adds to your app, see the section
titled "Express Helpers" near the bottom of this README.

Example Application

There is an example application at ./example

To run it:

$ cd example
$ node server.js

Important - Some OAuth Providers do not allow callbacks to localhost, so you will need to create a localhost
alias called local.host. Make sure you set up your /etc/hosts so that 127.0.0.1 is also
associated with 'local.host'. So inside your /etc/hosts file, one of the lines will look like:

127.0.0.1 localhost local.host

Then point your browser to http://local.host:3000

Tests

$ npm install everyauth --dev

Then, update test/creds.js with credentials that the integration tests use to
login to each 3rd party service.

$ make test

Accessing the User

If you are using express or connect, then everyauth
provides an easy way to access the user as:

- req.user from your app server
- everyauth.user via the everyauth helper accessible from your express views.
- user as a helper accessible from your express views

To access the user, configure everyauth.everymodule.findUserById and
optionally everyauth.everymodule.userPkey.
For example, using mongoose:

`javascript
everyauth.everymodule.findUserById( function (userId, callback) {
User.findById(userId, callback);
// callback has the signature, function (err, user) {...}
});
`

If you need access to the request object the function can have three arguments:

`javascript
everyauth.everymodule.findUserById( function (req, userId, callback) {

// use the request in some way ...

// callback has the signature, function (err, user) {...}
});
`

Once you have configured this method, you now have access to the user object
that was fetched anywhere in your server app code as req.user. For instance:

`javascript
var app = require('express').createServer()

// Configure your app

app.get('/', function (req, res) {
console.log(req.user); // FTW!
res.render('home');
});
`

Moreover, you can access the user in your views as everyauth.user or as user.

//- Inside ./views/home.jade
span.user-id= everyauth.user.name
#user-id= user.id

everyauth assumes that you store your users with an id property. If not --
e.g, if you adopt the convention user.uid over user.id -- then just make
sure to configure the everyauth.everymodule.userPkey parameter:

`javascript
everyauth.everymodule.userPkey('uid');
`

Express Helpers

If you are using express, everyauth comes with some useful dynamic helpers.
To enable them:

`javascript
var express = require('express')
, everyauth = require('everyauth')
, app = express.createServer();

everyauth.helpExpress(app);
`

Then, from within your views, you will have access to the following helpers methods
attached to the helper, everyauth:

- everyauth.loggedIn
- everyauth.user - the User document associated with the session
- everyauth.facebook - The is equivalent to what is stored at req.session.auth.facebook,
so you can do things like ...
- everyauth.facebook.user - returns the user json provided from the OAuth provider.
- everyauth.facebook.accessToken - returns the access_token provided from the OAuth provider
for authorized API calls on behalf of the user.
- And you also get this pattern for other modules - e.g., everyauth.twitter.user,
everyauth.github.user, etc.

You also get access to the view helper

- user - the same as everyauth.user above

As an example of how you would use these, consider the following ./views/user.jade jade template:

.user-id
.label User Id
.value #{user.id}
.facebook-id
.label User Facebook Id
.value #{everyauth.facebook.user.id}

If you already have an express helper named user, then you can configure
everyauth to use a different helper name to access the user object that
everyauth manages. To do so, leverage the userAlias option for
everyauth.helpExpress:

`javascript
everyauth.helpExpress(app, { userAlias: '__user__' });
`

Then, you could access the user object in your view with the helper __user__
instead of the default helper user. So you can compare with the default use
of helpers given previously, the alternative leveraging userAlias would look like:

.user-id
.label User Id
.value #{__user__.id}
.facebook-id
.label User Facebook Id
.value #{everyauth.facebook.user.id}

everyauth also provides convenience methods on the ServerRequest instance req.
From any scope that has access to req, you get the following convenience getters and methods:

- req.loggedIn - a Boolean getter that tells you if the request is by a logged in user
- req.user - the User document associated with the session
- req.logout() - clears the sesion of your auth data

Logging Out

If you integrate everyauth with connect, then everyauth automatically
sets up a logoutPath at GET /logout for your app. It also
sets a default handler for your logout route that clears your session
of auth information and redirects them to '/'.

To over-write the logout path:

`javascript
everyauth.everymodule.logoutPath('/bye');
`

To over-write the logout redirect path:

`javascript
everyauth.everymodule.logoutRedirectPath('/navigate/to/after/logout');
`

To over-write the logout handler:

`javascript
everyauth.everymodule.handleLogout( function (req, res) {
// Put you extra logic here

req.logout(); // The logout method is added for you by everyauth, too

// And/or put your extra logic here

this.redirect(res, this.logoutRedirectPath());
});
`

Custom redirect on password-based login or registration

You may want your own callback that decides where to send a user after login or registration. One way of doing this is with the respondToLoginSucceed and respondToRegistrationSucceed methods. This assumes that you have set a .redirectTo property on your req.session object:

`javascript
everyauth.password
.respondToLoginSucceed( function (res, user, data) {
if (user) {
this.redirect(res, data.session.redirectTo)
}
})
.respondToRegistrationSucceed( function (res, user, data) {
this.redirect(res, data.session.redirectTo)
})
`

If you are using express and want your redirects to be subject to express
redirect mapping), you can
overwrite redirect method employed by everyauth.

`javascript
everyauth.everymodule
.performRedirect( function (res, location) {
res.redirect(location, 303);
});
`

A newly defined method will be used by everyauth to perform all redirects.

Auth Strategy Instructions

Facebook Connect

`javascript
var everyauth = require('everyauth')
, connect = require('connect');

everyauth.facebook
.appId('YOUR APP ID HERE')
.appSecret('YOUR APP SECRET HERE')
.handleAuthCallbackError( function (req, res) {
// If a user denies your app, Facebook will redirect the user to
// /auth/facebook/callback?error_reason=user_denied&error=access_denied&error_description=The+user+denied+your+request.
// This configurable route handler defines how you want to respond to
// that.
// If you do not configure this, everyauth renders a default fallback
// view notifying the user that their authentication failed and why.
})
.findOrCreateUser( function (session, accessToken, accessTokExtra, fbUserMetadata) {
// find or create user logic goes here
})
.redirectPath('/');

var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`

You can also configure more parameters (most are set to defaults) via
the same chainable API:

`javascript
everyauth.facebook
.entryPath('/auth/facebook')
.callbackPath('/auth/facebook/callback')
.scope('email') // Defaults to undefined
.fields('id,name,email,picture') // Controls the returned fields. Defaults to undefined
`

If you want to see what the current value of a
configured parameter is, you can do so via:

`javascript
everyauth.facebook.scope(); // undefined
everyauth.facebook.fields(); // undefined
everyauth.facebook.entryPath(); // '/auth/facebook'
`

To see all parameters that are configurable, the following will return an
object whose parameter name keys map to description values:

`javascript
everyauth.facebook.configurable();
`

Facebook provides many different
permissions
for which your app can ask your user. This is bundled up in the scope query
paremter sent with the oauth request to Facebook. While your app may require
several different permissions from Facebook, Facebook recommends that you only
ask for these permissions incrementally, as you need them. For example, you might
want to only ask for the "email" scope upon registration. At the same time, for
another user, you may want to ask for "user_status" permissions because they
have progressed further along in your application.

everyauth enables you to specify the "scope" dynamically with a second
variation of the configurable scope. In addition to the first variation
that looks like:

`javascript
everyauth.facebook
.scope('email,user_status');
`

you can have greater dynamic control over "scope" via the second variation of scope:

`javascript
everyauth.facebook
.scope( function (req, res) {
var session = req.session;
switch (session.userPhase) {
case 'registration':
return 'email';
case 'share-media':
return 'email,user_status';
}
});

`

If you are programming for mobile, you can bring up the facebook mobile OAuth
dialog instead of the traditional desktop browser-based one by just adding
mobile(true) to your configuration as seen here:

`javascript
everyauth.facebook
.mobile(true)
.appId('YOUR APP ID HERE')
.appSecret('YOUR APP SECRET HERE')
// rest of configuration
`

Twitter OAuth

`javascript
var everyauth = require('everyauth')
, connect = require('connect');

everyauth.twitter
.consumerKey('YOUR CONSUMER ID HERE')
.consumerSecret('YOUR CONSUMER SECRET HERE')
.findOrCreateUser( function (session, accessToken, accessTokenSecret, twitterUserMetadata) {
// find or create user logic goes here
})
.redirectPath('/');

var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`

Important - Some developers forget to do the following, and it causes them to have issues with everyauth.
Please make sure to do the following: When you set up your app at http://dev.twitter.com/, make sure that your callback url is set up to
include that path '/auth/twitter/callback/'. In general, when dealing with OAuth or OAuth2 modules
provided by everyauth, the default callback path is always set up to follow the pattern
'/auth/#{moduleName}/callback', so just ensure that you configure your OAuth settings accordingly with
the OAuth provider -- in this case, the "Edit Application Settings" section for your app at http://dev.twitter.com.

Alternatively, you can specify the callback url at the application level by configuring callbackPath (which
has a default configuration of "/auth/twitter/callback"):

`javascript
everyauth.twitter
.consumerKey('YOUR CONSUMER ID HERE')
.consumerSecret('YOUR CONSUMER SECRET HERE')
.callbackPath('/custom/twitter/callback/path')
.findOrCreateUser( function (session, accessToken, accessTokenSecret, twitterUserMetadata) {
// find or create user logic goes here
})
.redirectPath('/');
`

So if your hostname is example.com, then this configuration will over-ride the dev.twitter.com callback url configuration.
Instead, Twitter will redirect back to example.com/custom/twitter/callback/path in the example just given above.

You can also configure more parameters (most are set to defaults) via
the same chainable API:

`javascript
everyauth.twitter
.entryPath('/auth/twitter')
.callbackPath('/auth/twitter/callback');
`

If you want to see what the current value of a
configured parameter is, you can do so via:

`javascript
everyauth.twitter.callbackPath(); // '/auth/twitter/callback'
everyauth.twitter.entryPath(); // '/auth/twitter'
`

To see all parameters that are configurable, the following will return an
object whose parameter name keys map to description values:

`javascript
everyauth.twitter.configurable();
`

Password Authentication

`javascript
var everyauth = require('everyauth')
, connect = require('connect');

everyauth.password
.getLoginPath('/login') // Uri path to the login page
.postLoginPath('/login') // Uri path that your login form POSTs to
.loginView('a string of html; OR the name of the jade/etc-view-engine view')
.authenticate( function (login, password) {
// Either, we return a user or an array of errors if doing sync auth.
// Or, we return a Promise that can fulfill to promise.fulfill(user) or promise.fulfill(errors)
// errors is an array of error message strings
//
// e.g.,
// Example 1 - Sync Example
// if (usersByLogin[login] && usersByLogin[login].password === password) {
// return usersByLogin[login];
// } else {
// return ['Login failed'];
// }
//
// Example 2 - Async Example
// var promise = this.Promise()
// YourUserModel.find({ login: login}, function (err, user) {
// if (err) return promise.fulfill([err]);
// promise.fulfill(user);
// }
// return promise;
})
.loginSuccessRedirect('/') // Where to redirect to after a login

// If login fails, we render the errors via the login view template,
// so just make sure your loginView() template incorporates an errors local.
// See './example/views/login.jade'

.getRegisterPath('/register') // Uri path to the registration page
.postRegisterPath('/register') // The Uri path that your registration form POSTs to
.registerView('a string of html; OR the name of the jade/etc-view-engine view')
.validateRegistration( function (newUserAttributes) {
// Validate the registration input
// Return undefined, null, or [] if validation succeeds
// Return an array of error messages (or Promise promising this array)
// if validation fails
//
// e.g., assuming you define validate with the following signature
// var errors = validate(login, password, extraParams);
// return errors;
//
// The errors you return show up as an errors local in your jade template
})
.registerUser( function (newUserAttributes) {
// This step is only executed if we pass the validateRegistration step without
// any errors.
//
// Returns a user (or a Promise that promises a user) after adding it to
// some user store.
//
// As an edge case, sometimes your database may make you aware of violation
// of the unique login index, so if this error is sent back in an async
// callback, then you can just return that error as a single element array
// containing just that error message, and everyauth will automatically handle
// that as a failed registration. Again, you will have access to this error via
// the errors local in your register view jade template.
// e.g.,
// var promise = this.Promise();
// User.create(newUserAttributes, function (err, user) {
// if (err) return promise.fulfill([err]);
// promise.fulfill(user);
// });
// return promise;
//
// Note: Index and db-driven validations are the only validations that occur
// here; all other validations occur in the validateRegistration step documented above.
})
.registerSuccessRedirect('/'); // Where to redirect to after a successful registration

var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`

You can also configure more parameters (most are set to defaults) via
the same chainable API:

`javascript
everyauth.password
.loginFormFieldName('login') // Defaults to 'login'
.passwordFormFieldName('password') // Defaults to 'password'
.loginLayout('custom_login_layout') // Only with express
.registerLayout('custom reg_layout') // Only with express
.loginLocals(fn); // See Recipe 3 below
`

If you want to see what the current value of a
configured parameter is, you can do so via:

`javascript
everyauth.password.loginFormFieldName(); // 'login'
everyauth.password.passwordFormFieldName(); // 'password'
`

To see all parameters that are configurable, the following will return an
object whose parameter name keys map to description values:

`javascript
everyauth.password.configurable();
`

$3

Sometimes your registration will ask for more information from the user besides the login and password.

For this particular scenario, you can configure the optional step, extractExtraRegistrationParams.

`javascript
everyauth.password.extractExtraRegistrationParams( function (req) {
return {
phone: req.body.phone
, name: {
first: req.body.first_name
, last: req.body.last_name
}
};
});
`

Then, you will have access to this data from within your configured
validateRegistration and registerUser:

`javascript
everyauth.password
.validateRegistration( function (newUserAttributes) {
var phone = newUserAttributes.phone
, firstName = newUserAttributes.name.first
, lastName = newUserAttributes.name.last;
})
.registerUser( function (newUserAttributes) {
var phone = newUserAttributes.phone
, firstName = newUserAttributes.name.first
, lastName = newUserAttributes.name.last;
});
`

$3

By default, everyauth uses the field and user key name login during the
registration and login process.

Sometimes, you want to use email or phone instead of login. Moreover,
you also want to validate email and phone fields upon registration.

everyauth provides an easy way to do this:

`javascript
everyauth.password.loginWith('email');

// OR

everyauth.password.loginWith('phone');
`

With simple login configuration like this, you get email (or phone) validation
in addition to renaming of the form field and user key corresponding to what
otherwise would typically be referred to as 'login'.

$3

If you are using express, you are able to pass variables from your app
context to your view context via local variables. everyauth provides
several convenience local vars for your views, but sometimes you will want
to augment this set of local vars with additional locals.

So everyauth also provides a mechanism for you to do so via the following
configurables:

`javascript
everyauth.password.loginLocals(...);
everyauth.password.registerLocals(...);
`

loginLocals and registerLocals configuration have symmetrical APIs, so I
will only cover loginLocals here to illustrate how to use both.

You can configure this parameter in one of 3 ways. Why 3? Because there are 3 types of ways that you can retrieve your locals.

1. Static local vars that never change values:

`javascript
everyauth.password.loginLocals({
title: 'Login'
});
`
2. Dynamic synchronous local vars that depend on the incoming request, but whose values are retrieved synchronously

`javascript
everyauth.password.loginLocals( function (req, res) {
var sess = req.session;
return {
isReturning: sess.isReturning
};
});
`
3. Dynamic asynchronous local vars

`javascript
everyauth.password.loginLocals( function (req, res, done) {
asyncCall( function ( err, data) {
if (err) return done(err);
done(null, {
title: il8n.titleInLanguage('Login Page', il8n.language(data.geo))
});
});
});
`

$3

By default, everyauth.password automatically

- validates that the login (or email or phone, depending on what you authenticate with -- see Password Recipe 2) is present in the login http request,
- validates that the password is present
- validates that an email login is a correctly formatted email
- validates that a phone login is a valid phone number

If any of these validations fail, then the appropriate errors are generated and accessible to you in your view via the errors view local variable.

If you want to add additional validations beyond this, you can do so by configuring the step, validateRegistration:

`javascript
everyauth.password
.validateRegistration( function (newUserAttributes, baseErrors) {
// Here, newUserAttributes is the hash of parameters extracted from the incoming request.
// baseErrors is the array of errors generated by the default automatic validation outlined above
// in this same recipe.

// First, validate your errors. Here, validateUser is a made up function
var moreErrors = validateUser( newUserAttributes );
if (moreErrors.length) baseErrors.push.apply(baseErrors, moreErrors);

// Return the array of errors, so your view has access to them.
return baseErrors;
});
`

$3

By default, everyauth is agnostic about how you decide to store your users and
therefore passwords. However, one should always use password hashing and
salting for security.

Here's an example of how to incorporate password hashing into everyauth using
bcrypt hashing. The idea is to store a salt and hash value inside your user object
instead of the password. The hash value is generated from the password (sent with a
registration or login request) and unique salt per user, using the bcrypt algorithm.

`javascript
// Make sure to npm install bcrypt
var bcrypt = require('bcrypt');

everyauth.password
.registerUser( function (newUserAttrs) {
var promise = this.Promise()
, password = newUserAttrs.password;

delete newUserAttrs.password; // Don't store password
newUserAttrs.salt = bcrypt.genSaltSync(10);
newUserAttrs.hash = bcrypt.hashSync(password, salt);

// Create a new user in your data store
createUser( newUserAttrs, function (err, createdUser) {
if (err) return promise.fail(err);
return promise.fulfill(createdUser);
});

return promise;
})
.authenticate( function (login, password) {
var promise
, errors = [];
if (!login) errors.push('Missing login.');
if (!password) errors.push('Missing password.');
if (errors.length) return errors;

promise = this.Promise();

// findUser passes an error or user to a callback after finding the
// user by login
findUser( login, function (err, user) {
if (err) {
errors.push(err.message || err);
return promise.fulfill(errors);
}
if (!user) {
errors.push('User with login ' + login + ' does not exist.');
return promise.fulfill(errors);
}
bcrypt.compare(password, user.hash, function (err, didSucceed) {
if (err) {
return promise.fail(err);
errors.push('Wrong password.');
return promise.fulfill(errors);
}
if (didSucceed) return promise.fulfill(user);
errors.push('Wrong password.');
return promise.fulfill(errors);
});
});

return promise;
})

You will first need to register your application to get the consumer key and secret.

`javascript
everyauth.mendeley
.consumerKey('YOUR CONSUMER KEY HERE')
.consumerSecret('YOUR CONSUMER SECRET HERE')
.findOrCreateUser( function (sess, accessToken, accessSecret, user) {
// find or create user logic goes here
//
// e.g.,
// return usersByMendeleyId[user.main.profile_id] || (usersByMendeleyId[user.main.profile_id] = user);
})
.redirectPath('/');

var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`

OpenID protocol allows you to use an openid auth request. You can read more information about it here http://openid.net/

`javascript
var everyauth = require('everyauth')
, connect = require('connect');

everyauth.openid
.myHostname('http://localhost:3000')
.simpleRegistration({
"nickname" : true
, "email" : true
, "fullname" : true
, "dob" : true
, "gender" : true
, "postcode" : true
, "country" : true
, "language" : true
, "timezone" : true
})
.attributeExchange({
"http://axschema.org/contact/email" : "required"
, "http://axschema.org/namePerson/friendly" : "required"
, "http://axschema.org/namePerson" : "required"
, "http://axschema.org/namePerson/first" : "required"
, "http://axschema.org/contact/country/home": "required"
, "http://axschema.org/media/image/default" : "required"
, "http://axschema.org/x/media/signature" : "required"
})
.openidURLField('openid_identifier'); //The POST variable used to get the OpenID
.findOrCreateUser( function(session, openIdUserAttributes) {
// find or create user logic goes here
})
.redirectPath('/');

var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`

OpenID+OAuth Hybrid protocol allows you to combine an openid auth request with a oauth access request. You can read more information about it here http://code.google.com/apis/accounts/docs/OpenID.html

Register your domain with Google
here and write down the
consumer key and consumer secret generated during the domain registration.

`javascript
var everyauth = require('everyauth')
, connect = require('connect');

everyauth.googlehybrid
.consumerKey('YOUR CONSUMER KEY HERE')
.consumerSecret('YOUR CONSUMER SECRET HERE')
.scope(['GOOGLE API SCOPE','GOOGLE API SCOPE'])
.findOrCreateUser( function(session, userAttributes) {
// find or create user logic goes here
})
.redirectPath('/');

var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`

$3

You will need to register for an app id here. Implementation details follow the same pattern as with other
oauth2 implementations.

`javascript

var everyauth = require('everyauth')
, connect = require('connect');

everyauth.smarterer
.appId('YOUR APP ID')
.appSecret('YOUR APP SECRET')
.findOrCreateUser(function(session, accessToken, accessTokenSecret, userData) {
// find or create user logic goes here
// userData.userName will contain the smarterer username for the authenticated user
// userData.badges will contain the scores on quizes
})
.redirectPath('/');

var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`




$3

`javascript
var everyauth = require('everyauth')
, connect = require('connect');

everyauth.box
.apiKey('YOUR API KEY')
.findOrCreateUser( function (sess, authToken, boxUser) {
// find or create user logic goes here
//
// e.g.,
// return usersByBoxId[user.user_id] || (usersByBoxId[user.user_id] = user);
})
.redirectPath('/');

var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`

You can also configure more parameters (most are set to defaults) via
the same chainable API:

`javascript
everyauth.box
.entryPath('/auth/box')
.callbackPath('/auth/box/callback');
`

If you want to see what the current value of a
configured parameter is, you can do so via:

`javascript
everyauth.box.callbackPath(); // '/auth/box/callback'
everyauth.box.entryPath(); // '/auth/box'
`

To see all parameters that are configurable, the following will return an
object whose parameter name keys map to description values:

`javascript
everyauth.box.configurable();
`

The LDAP module is still in development. Do not use it in production yet.

Install OpenLDAP client libraries:

$ apt-get install slapd ldap-utils

Install node-ldapauth:

`javascript
var everyauth = require('everyauth')
, connect = require('connect');

everyauth.ldap
.host('your.ldap.host')
.port(389)

// The ldap module inherits from the password module, so
// refer to the password module instructions several sections above
// in this README.
// You do not need to configure the authenticate step as instructed
// by password because the ldap module already does that for you.
// Moreover, all the registration related steps and configurable parameters
// are no longer valid
.getLoginPath(...)
.postLoginPath(...)
.loginView(...)
.loginSuccessRedirect(...);

var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`

You will need to create a Windows Azure ACS namespace. The only caveat when creating the namespace is setting the "Return URL". You will probably create one Relying Party for each environment (dev, qa, prod) and each of them will have a different "Return URL". For instance, dev will be http://localhost:port/auth/azureacs/callback and prod could be https://myapp.com/auth/azureacs/callback (notice the /auth/azureacs/callback, that's where the module will listen the POST with the token from ACS)

`javascript
var everyauth = require('everyauth')
, connect = require('connect');

everyauth.azureacs
.identityProviderUrl('https://YOURNAMESPACE.accesscontrol.windows.net/v2/wsfederation/')
.entryPath('/auth/azureacs')
.callbackPath('/auth/azureacs/callback')
.signingKey('d0jul....YOUR_SIGNINGK=_KEY......OEvz24=')
.realm('YOUR_APPLICATION_REALM_IDENTIFIER')
.homeRealm('') // if you want to use a default idp (like google/liveid)
.tokenFormat('swt') // only swt supported for now
.findOrCreateUser( function (session, acsUser) {
// you could enrich the "user" entity by storing/fetching the user from a db
return null;
});
.redirectPath('/');


var routes = function (app) {
// Define your routes here
};

connect(
connect.bodyParser()
, connect.cookieParser()
, connect.session({secret: 'whodunnit'})
, everyauth.middleware()
, connect.router(routes);
).listen(3000);
`

If you want to see what the current value of a
configured parameter is, you can do so via:

`javascript
everyauth.box.callbackPath(); // '/auth/azureacs/callback'
`

To see all parameters that are configurable, the following will return an
object whose parameter name keys map to description values:

`javascript
everyauth.box.configurable();
`

Configuring a Module

everyauth was built with powerful configuration needs in mind.

Every module comes with a set of parameters that you can configure
directly. To see a list of those parameters on a per module basis,
with descriptions about what they do, enter the following into the
node REPL (to access the REPL, just type node at the command line)

> var ea = require('everyauth');
> ea.facebook.configurable();

For example, you will see that one of the configuration parameters is
moduleTimeout, which is described to be how long to wait per step
before timing out and invoking any timeout callbacks

Every configuration parameter corresponds to a method of the same name
on the auth module under consideration (i.e., in this case
ea.facebook). To create or over-write that parameter, just
call that method with the new value as the argument:

`javascript
ea.facebook
.moduleTimeout( 4000 ); // Wait 4 seconds before timing out any step
// involved in the facebook auth process
`

Configuration parameters can be scalars. But they can be anything. For
example, they can also be functions, too. The facebook module has a
configurable step named findOrCreateUser that is described as
"STEP FN [findOrCreateUser] function encapsulating the logic for the step
fetchOAuthUser.". What this means is that this configures the
function (i.e., "FN") that encapsulates the logic of this step.

`javascript
ea.facebook
.findOrCreateUser( function (session, accessToken, extra, oauthUser) {
// find or create user logic goes here
});
`

How do we know what arguments the function takes?
We elaborate more about step function configuration in our
Introspection section below.

$3

Everyauth also supports a special method configure for coffee-script
aficionados. Coffee and chainable APIs often don't mix well. As an alternative,
you can configure an everyauth module using an Object passed to configure:

`coffee
everyauth.dropbox.configure
consumerKey: conf.dropbox.consumerKey
consumerSecret: conf.dropbox.consumerSecret
findOrCreateUser: (sess, accessToken, accessSecret, dbMeta) -> users[dbMeta.uid] or= addUser('dropbox', dbMeta)
redirectPath: '/'
`

Introspection

everyauth provides convenient methods and getters for finding out
about any module.

Show all configurable parameters with their descriptions:

`javascript
everyauth.facebook.configurable();
`

Show the value of a single configurable parameter:

`javascript
// Get the value of the configurable callbackPath parameter
everyauth.facebook.callbackPath(); // => '/auth/facebook/callback'
`

Show the declared routes (pretty printed):

`javascript
everyauth.facebook.routes;
`

Show the steps initiated by a given route:

`javascript
everyauth.facebook.route.get.entryPath.steps;
everyauth.facebook.route.get.callbackPath.steps;
`

Sometimes you need to set up additional steps for a given auth
module, by defining that step in your app. For example, the
set of steps triggered when someone requests the facebook
module's callbackPath contains a step that you must define
in your app. To see what that step is, you can introspect
the callbackPath route with the facebook module.

`javascript
everyauth.facebook.route.get.callbackPath.steps.incomplete;
// => [ { name: 'findOrCreateUser',
// error: 'is missing: its function' } ]
`

This tells you that you must define the function that defines the
logic for the findOrCreateUser step. To see what the function
signature looks like for this step:

`javascript
var matchingStep =
everyauth.facebook.route.get.callbackPath.steps.filter( function (step) {
return step.name === 'findOrCreateUser';
})[0];
// { name: 'findOrCreateUser',
// accepts: [ 'session', 'accessToken', 'extra', 'oauthUser' ],
// promises: [ 'user' ] }
`

This tells you that the function should take the following 4 arguments:

`javascript
function (session, accessToken, extra, oauthUser) {
...
}
`

And that the function should return a user that is a user object or
a Promise that promises a user object.

`javascript
// For synchronous lookup situations, you can return a user
function (session, accessToken, extra, oauthUser) {
...
return { id: 'some user id', username: 'some user name' };
}

// OR

// For asynchronous lookup situations, you must return a Promise that
// will be fulfilled with a user later on
function (session, accessToken, extra, oauthUser) {
var promise = this.Promise();
asyncFindUser( function (err, user) {
if (err) return promise.fail(err);
promise.fulfill(user);
});
return promise;
}
`

You add this function as the block for the step findOrCreateUser just like
you configure any other configurable parameter in your auth module:

`javascript
everyauth.facebook
.findOrCreateUser( function (session, accessToken, extra, oauthUser) {
// Logic goes here
});
`

There are also several other introspection tools at your disposal:

For example, to show the submodules of an auth module by name:

`javascript
everyauth.oauth2.submodules;
`

Other introspection tools to describe (explanations coming soon):

- Invalid Steps

`javascript
everyauth.facebook.routes.get.callbackPath.steps.invalid
`

Debugging

$3

To turn on debugging:

`javascript
everyauth.debug = true;
`

Each everyauth auth strategy module is composed of steps. As each step begins and ends, everyauth will print out to the console the beginning and end of each step. So by turning on the debug flag, you get insight into what step everyauth is executing at any time.

For example, here is some example debugging information output to the console
during a Facebook Connect authorization:

`
starting step - getAuthUri
...finished step
starting step - requestAuthUri
...finished step
starting step - getCode
...finished step
starting step - getAccessToken
...finished step
starting step - fetchOAuthUser
...finished step
starting step - getSession
...finished step
starting step - findOrCreateUser
...finished step
starting step - compile
...finished step
starting step - addToSession
...finished step
starting step - sendResponse
...finished step
`

$3

By default, all modules handle errors by throwing them. That said, everyauth allows
you to over-ride this behavior.

You can configure error handling at the module and step level. To handle all
errors in the same manner across all auth modules that you use, do the following.

`javascript
everyauth.everymodule.moduleErrback( function (err) {
// Do something with the err -- e.g., log it, throw it
});
`

You can also configure your error handling on a per module basis. So, for example, if
you want to handle errors during the Facebook module differently than in other modules:


`javascript
everyauth.facebook.moduleErrback( function (err) {
// Do something with the err -- e.g., log it, throw it
});
`

$3

By default, every module has 10 seconds to complete each step. If a step takes longer than 10 seconds to complete, then everyauth will pass a timeout error to your configured error handler (see section "Configure Error Handling" above).

If you would like to increase or decrease the timeout period across all modules, you can do so via:

`javascript
everyauth.everymodule.moduleTimeout(2000); // Wait 2 seconds per step instead before timing out
`

You can eliminate the timeout altogether by configuring your timeouts to -1:

`javascript
everyauth.everymodule.moduleTimeout(-1);
`

You can also configure the timeout period on a per module basis. For example, the following will result in the facebook module having 3 seconds to complete each step before timing out; all other modules will have the default 10 seconds per step before timing out.

`javascript
everyauth.facebook.moduleTimeout(3000); // Wait 3 seconds
``
