aurelia-auth is a token-based authentication plugin for Aurelia with support for popular social authentication providers (Google, Twitter, Facebook, LinkedIn, Windows Live, FourSquare, Yahoo, Github, Instagram ) and a local stragegy, i.e. simple username (email) and password.
aurelia-auth is a port of the great Satellizer library to ES6 and packaged as an Aurelia plugin.
Other OAuth1 and Oauth2 than the above mentioned providers can be simply added by editing the extensible configuration file.
Basically, aurelia-auth does not use any cookies but relies on a JWT (json web token) stored in the local storage of the browser:
Both local storage as well as session storage can be used (via the aurelia-auth security configuration file).
The aurelia token will be sent automatically to your API when the user is authenticated.
Obviously, the prerequisites (NodeJs, Gulp) from Aurelia. Since aurelia-auth is an Aurelia plugin , we presume here you have your Aurelia project up and running.
jspm install aurelia-auth
aurelia-auth does not contain any UI widgets. It's conceived as a simple service with following interface:
login(email, password)
logout(redirectUri)
authenticate(provider, redirect, userData)
signup(displayName, email, password)
getMe()
isAuthenticated()
getTokenPayload()
unlink(provider)Login is used for the local authentication strategy (email + password). Authenticate is for social media authentication. Authenticate is also used for linking a social media account to an existing account.
Add an javascript file to your project where you will store the aurelia-auth security configuration data. Call it for example authConfig.js. Since this file is available via the browser, it should never contain sensitive data. Note that for OAuth the clientId is non sensitive. The client secret is sensitive data and should be only available server side. The aurelia-auth config file is compatible with the original Satellizer config file, easing the migration of AngularJs projects to Aurelia.
var configForDevelopment = {
providers: {
google: {
clientId: '239531826023-ibk10mb9p7ull54j55a61og5lvnjrff6.apps.googleusercontent.com'
}
,
linkedin:{
clientId:'778mif8zyqbei7'
},
facebook:{
clientId:'1452782111708498'
}
}
};
var configForProduction = {
providers: {
google: {
clientId: '239531826023-3ludu3934rmcra3oqscc1gid3l9o497i.apps.googleusercontent.com'
}
,
linkedin:{
clientId:'7561959vdub4x1'
},
facebook:{
clientId:'1653908914832509'
}
}
};
var config ;
if (window.location.hostname==='localhost') {
config = configForDevelopment;
}
else{
config = configForProduction;
}
export default config;The above configuration file can cope with a development and production version (not mandatory of course). The strategy is that when your run on localhost, the development configuration file is used, otherwise the production configuration file is taken.
In your aurelia configuration file, add the plugin and inject the aurelia-auth security configuration file :
import config from './authConfig';
export function configure(aurelia) {
aurelia.use
.standardConfiguration()
.developmentLogging()
.plugin('aurelia-animator-css')
.plugin('aurelia-auth', (baseConfig)=>{
baseConfig.configure(config);
});
aurelia.start().then(a => a.setRoot());
}The above aurelia configuration file consumes the aurelia-auth security configuration file.
In your aurelia app file, inject the {FetchConfig} class from aurelia-auth. We need to explicitely opt-in for the configuration of your fetch client by calling the configure function of the FetchConfig class:
import 'bootstrap';
import {inject} from 'aurelia-framework';
import {Router} from 'aurelia-router';
import {FetchConfig} from 'aurelia-auth';
@inject(Router,FetchConfig, AppRouterConfig )
export class App {
constructor(router, fetchConfig, appRouterConfig){
this.router = router;
this.fetchConfig = fetchConfig;
}
activate(){
this.fetchConfig.configure();
}
}Allthough the Fetch Client is the preferred 'http client' for aurelia, there is also support for aurelia-http-client.
The configuration of aurelia-http-client is similar to aurelia-fetch-client.
In your aurelia app file, inject the HttpClientConfig.
In the activate step, invoke the configure() method to send Authorization tokens with every HttpClient request.
import {inject} from 'aurelia-framework';
import HttpClientConfig from 'aurelia-auth/app.httpClient.config';
@inject(Router,HttpClientConfig,AppRouterConfig )
export class App {
constructor(router, httpClientConfig){
this.router = router;
this.httpClientConfig = httpClientConfig;
}
activate(){
this.httpClientConfig.configure();
}
...
}See aurelia-auth-samples for more details.
Button actions are passed to the corresponding view model via a simple click.delegate:
<button class="btn btn-block btn-google-plus" click.delegate="authenticate('google')">
<span class="ion-social-googleplus"></span>Sign in with Google
</button>The login view model will speak directly with the aurelia-auth service, which is made available via constructor injection.
import {AuthService} from 'aurelia-auth';
import {inject} from 'aurelia-framework';
@inject(AuthService)
export class Login{
constructor(auth){
this.auth = auth;
};
heading = 'Login';
email='';
password='';
login(){
return this.auth.login(this.email, this.password)
.then(response=>{
console.log("success logged " + response);
})
.catch(err=>{
console.log("login failure");
});
};
authenticate(name){
return this.auth.authenticate(name, false, null)
.then((response)=>{
console.log("auth response " + response);
});
}
}On the profile page, social media accounts can be linked and unlinked. For a nice UI experience, use if.bind for either showing the link or unlink button:
<button class="btn btn-sm btn-danger" if.bind="profile.facebook" click.delegate="unlink('facebook')">
<i class="ion-social-facebook"></i> Unlink Facebook Account
</button>
<button class="btn btn-sm btn-primary" if.bind="!profile.facebook" click.delegate="link('facebook')">
<i class="ion-social-facebook"></i> Link Facebook Account
</button>The logout and profile links are only shown when the user is authenticated, whereas the login link is only visible when the user is not authenticated.
<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<li repeat.for="row of router.navigation | authFilter: isAuthenticated" class="${row.isActive ? 'active' : ''}">
<a data-toggle="collapse" data-target="#bs-example-navbar-collapse-1.in" href.bind="row.href">${row.title}</a>
</li>
</ul>
<ul if.bind="!isAuthenticated" class="nav navbar-nav navbar-right">
<li><a href="/#/login">Login</a></li>
<li><a href="/#/signup">Sign up</a></li>
</ul>
<ul if.bind="isAuthenticated" class="nav navbar-nav navbar-right">
<li><a href="/#/profile">Profile</a></li>
<li><a href="/#/logout">Logout</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li class="loader" if.bind="router.isNavigating">
<i class="fa fa-spinner fa-spin fa-2x"></i>
</li>
</ul>
</div>Menu items visibility can also be linked with the authFilter to the isAuthenticated value.
In the router config function, you can specifify an auth property in the routing map indicating wether or not the user needs to be authenticated in order to access the route:
configure(){
var appRouterConfig = function(config){
config.title = 'Aurelia';
config.addPipelineStep('authorize', AuthorizeStep); // Add a route filter to the authorize extensibility point.
config.map([
{ route: ['','welcome'], moduleId: './welcome', nav: true, title:'Welcome' },
{ route: 'flickr', moduleId: './flickr', nav: true, title:'Flickr' },
{ route: 'customer', moduleId: './customer', nav: true, title:'CRM', auth:true },
...
]);
};
this.router.configure(appRouterConfig);
}In the above example the customer route is only available for authenticated users.
