hi, I want to get getUserId() from session object and i am using fastify mercurius . In documentation, there is an example for only express, so can anyone here how can I pass the session in the context in mercurius?

Hey!

no, in integration tab there is graphql and in backend setup there is example for express only

@nkshah2 can help.

Right, so you want to follow the steps here: https://supertokens.com/docs/session/common-customizations/sessions/session-verification-in-api/verify-session which explains how to use the verifySession middleware (This page has docs for how to use it in fastify as well) That will give you access to the session object which you can then add to the graphlql context

I am using the preHandler hook to call verifySession middleware, still, I am getting session object undefined.

Can you show some code?

fastify.addHook( "preHandler", async (request: SessionRequest, reply: FastifyReply, done: () => void) => { await verifySession({ sessionRequired: false }); console.log(request.session); done(); } );

So because you have set sessionRequired as false, it goes through even if a session does not exist

Like rp said since session required is false it goes through if the user isn’t logged in Since this is a GraphQL route you want to keep session required false, in which case if the session is undefined it usually means you aren’t logged in

but i tried by logging in

So there could be some other reason why it's not working.. some misconfiguration

i currently don't have frontend app

How are you testing it?

i am just logging the req.session object

What recipe are you using?
