In here, you'll see how to implement SSO between Single Page Apps and Regular Web Apps using Auth0.
In this example, we have 3 applications: app1.com (single page app) app2.com (single page app) app3.com (regular web app)
Each application has its own folder in this repository with its own instructions on how to run it.
In order to be able to test SSO correctly, each application must have its own domain. For that, you can edit your /etc/hosts and make app1.com, app2.com and app3.com all point to 127.0.0.1.
For that, open /etc/hosts and edits as follows:
# Host Database
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost
127.0.0.1 app1.com
127.0.0.1 app2.com
127.0.0.1 app3.com
Once that is done just run all 3 applications as per the instructions on each README and go to http://app1.com:3000 to start using the applications.
