We are planning to build backend in two languages, javascript and python serverless functions

Since I'm working with a friend, who works in python

I think that's fine since I can do the login part in javascript?

Actually, I think vercel serverless functions would work

That's awesome.

supertokens work fine with ssr right?

Since the request should be able to go from both server and client

SuperTokens will work with SSR. Yes

Okay awesome.

Will it be possible to move from managed service to self hosted in future if wanted?

Yes. Though it may require some downtime as the data is moved. And there might be a few issues depending on which db you use. We use PostgreSQL.

I can’t guarantee that it’s going to be a very smooth transition though.

Also, since we have not explicitly made the lib to work with serverless functions, there might be a few issues you encounter along the way.

Yeah makes sense.

Does supertokens require state between requests?

It doesn’t require it. Though it has state so that subsequent requests can be served faster.

We have a plan to optimise that for serverless execution.

But haven’t executed on that yet

How's your support for flask and nuxt?

We offer only sessions for flask

So u will need to build out login yourself

Sessions means Authorization right?

Login means authentication?

So not authorisation strictly. But creating access and refresh tokens to access your apis post login

Authorisation includes access control as well, which we don’t have

So you will get functions like createNewSession (which you call when login is successful), verifySession, revokeSession etc...

How would we implement access control, by having a copy of user id and his access permissions in our database?

So if you are gonna be using only sessions, you will need to store the userIds with you (since your also doing login)

Access permissions, if you are using roles, can be inserted in the access token when u create a new session, and then read in any API after the session has been verified

If I were to combine flask and express backend, would this work?
