Livefyre Auth

livefyre-auth is an extension of auth with added modules to authenticate with Livefyre StreamHub Auth APIs in Livefyre-powered Apps.

Livefyre Component developers should use this. auth is Livefyre-agnositc.

.plugin(auth)

Plug in to an instance of auth

auth allows apps to publish and subscribe to login events, and to trigger auth-related actions separately from how the web page operator delegates the implementaiton details of their log in flow.

The plugin will watch for 'authenticate' events on auth that have Livefyre credentials, and it will then try to authenticate them and log the user in with auth.login({ livefyre: user })

It will also load a user from session on page load, and clear the session on auth logout events.

require('livefyre-auth').plugin(auth);

Note: To create a delegate for a non-production cluster, you'll need to pass the serverUrl as a second parameter to .plugin

require('livefyre-auth').plugin(auth, 'uat.livefyre.com');

.User

Create a Livefyre User model. It is rare that you'd create this directly. Check out .userService.fetch().

var LivefyreUser = require('livefyre-auth').User;
var user = new LivefyreUser();

Users have attributes that can be get, set, and unset.

User#get

Get an attribute

user.get('id');
user.get('displayName');

User#set

Set an attribute. This will emit events.

// set with key, val args
user.set('id', 1);
// or a key/value map
user.get({
    id: 2,
    displayName: 'ben'
});

User#unset

Unset an attribute. This will emit a change event.

user.unset('id');

User#on

Users are EventEmitters, and emit 'change' events when attributes change.

// Listen for any change
user.on('change', function (changes) {
    // changes is an object of attribute/value pairs
});
// Listen for change of a particular attribute
user.on('change:{attributeName}', function (newValue) {
    // newValue is the value the attribute was changed to    
})

User#isMod

Check if a User is known to be a a moderator of a scope. returns a Boolean.

// network
user.isMod({
    network: 'livefyre.com'
});
// siteId
user.isMod({
    siteId: '343434'
});
// collectionId
user.isMod({
    collectionId: '124124124'
});
// collection info
user.isMod({
    network: 'livefyre.com',
    siteId: '4',
    articleId: '169'
});

.permissions

Deals with reading permissions from Livefyre

.permissions.forCollection(token, collection, errback)

Get permissions for a Livefyre Authentication Token within a Collection.

var permissions = require('livefyre-auth').permissions;
var collection = {
    network: 'livefyre.com',
    siteId: '4',
    articleId: '169'
};
permissions.forCollection('my token', collection, function (err, userInfo) {
    // `userInfo` has data specific to the user in the context of the collection.
});

.permissions.getKeys(user, collection, errback)

Get the user's keys for this collection, in order to decrypt erefs etc.

permissions.getKeys(user, collection, function (err, keys) {
    // `keys` is an array of valid decryption keys.
});

.createDelegate(serverUrl)

Create an auth delegate object to be passed to auth.delegate(). This will configure auth to be controlled by Livefyre.com accounts and profiles. Livefyre Enterprise customers will rarely use this.

var livefyreAuthDelegate = require('livefyre-auth').createDelegate('http://livefyre.com');

auth.delegate(livefyreAuthDelegate);

// This would launch a Livefyre.com login window
auth.login();

.userService

Manages Users via Livefyre Auth API

.fetch(credentials, errback)

Fetch a LivefyreUser from the AuthAPI. If you pass collection info in your credentials, the User will be made with the right collectionAuthorizations.

var livefyreAuth = require('livefyre-auth');
var authCredentials = {
    serverUrl: 'http://livefyre.com',
    token: 'lol'
};
livefyreAuth.fetchUser(authCredentials, function (err, user, userInfo) {
    // do
});

.api

Fetch the Livefyre Auth API.

Use .updateUser(user, data) to update a LivefyreUser from the auth api response data

var authApi = require('livefyre-auth').api;

authApi(opts, function (err, userInfo) {
    if (err) {
        return errback(err);
    }
    var user = new LivefyreUser();
    authApi.updateUser(user, userInfo);
});

.session

Helpers for dealing with the Livefyre User session
