@tushar13293 I added you as a reviewer for this PR. This is basically the foundation for you to work with this app.

Please checkout this branch via git checkout minimal-routes && git pull and test the app for the following things:

• can you setup the newly required accounts app just from reading the updated README
• can you understand the basic application structure / do you know where is what, where to start if you would want to implement a feature (please go through the code carefully, take your time)
• can you login, logout
• can you find and execute the local scripts for linting and testing

If there is any issue in the code you don't understand, please use the review to add comments.

One issue i found was when i log in for the first time server asks for username/password (as it should) but after logging out it doesn't ask for login details again and logs me in automatically.

I think this is intended?

Everything else works great.

I see, this is because the OAuth workflow logs you in across apps, so if you log out from the teacher app you are not finally logged out. But for teachers we should implement a logout call to the OAuth server so they are 100% logged out. This however requires this first to be solved in the accounts application.

Since you found nothing else I will merge this now and create the respective issues. Thank you 👍
