ember-aws-cognito

This addon adds capability to use Cognito authentication for protecting private pages. It is built on top of the code provided by Amazon on https://github.com/aws-samples/aws-serverless-ember

Installation

Installation of the addon is done the usual way

ember install ember-aws-cognito

Usage

Once install, you then need to play the included blueprint to update your project file adding :

• AWS variables in 'environnement.js'

The standard cognito-login template uses a component based on bootstrap

    {{#login-cognito-bootstrap}}Bootstrap Login with Cognito{{/login-cognito-bootstrap}}

This is the only component provided at the time being by this addon.

Once all this done, you can add a private page by adding to its route the following code :

    authentication: Ember.inject.service(),
    beforeModel() {
        var auth = this.get('authentication');
        if (!auth.authenticated) {
            this.transitionTo('cognito-login');
        }
    },

AWS Cognito configuration

The Cognito User pool should be correctly set up to allow autehntication of the users.

Here is a sample for CloudFormation setup. Note that the field 'Parameters.AppClientName.Default' and Resources.CognitoUserPool.Properties.UserPoolName' should be updated to fit your current project.
