Django-allauth, JWT, Oauth

There are usually two login flows with social login: client-side ("Javascript SDK") and server-side. If your server needs to be authorised, it's usually a lot easier to go through the server-side flow. And that's also what all-auth does I think (and you didn't mention you use a frontend library like the blogpost you mentioned does).

Now the challenge is to provide the token from the server to the frontend. You would probably load the token in the HTML of the initialisation of the SPA, and then from Angular save the token client side (cookie, localStorage, etc.) so the session isn't lost on a refresh.

If you don't want the user to leave your app, you can open your /accounts/login/ or /accounts/signup/ url in a new window. In that new window they authorise your app, and your server receives the token upon return. There, you will have to generate a JWT token manually, and render that into the template so that javascript can access it. With js in that popup window, you can then communicate with your app that opened the popup and pass it the token – see this SO answer for an example – so it can save it.

Django-allauth provides signals that let you hook into the social login process. In your case, I would recommend subscribing to the allauth.socialaccount.signals.pre_social_login signal. The code will look something like this:

from allauth.socialaccount.signals import pre_social_login@receiver(pre_social_login)def create_jwt_token(sender, request, sociallogin, **kwargs):    # dig into the sociallogin object to find the new access token.

We used hello.js for O-Auth at the company I worked at.

1. You provide a shim on the Python end and get the refresh token and whatever other data needed once the user connects their social account.

2. We redirect them via Django to the page they attempted to access from their OAuth provider's page.

Each user still has their own email account which is needed for the JWT, but you could assume that whatever email is in the scope of their social account is their email then use django's functionality to create new users: User.objects.create(email=emailStringFromOauthData) etc.
