i had to add the catch

if you are using await, you can surround with try and catch

ok this seems better

let session = await supertokens.getSession(req, res, true).catch(er => null);
    if(!session){ return redirect(); }

@User , most of the queries you have can be answered via the node js docs: https://supertokens.io/docs/nodejs/usage-with-express/user-login

am getting this error today, right after init

Error: No SuperTokens core available to query

Can you please send your init code?

cause your server is working

Hey rp, can I use supertokens with next framework hosted on vercel serverless functions and mongodb database?

Hey @nxteword do you want to use the login feature or just session management?

Because for login, it only works MySQL and PostgreSQL at the moment

Whilst session works with mongo as well

Can you please point me to resources to learn about login and session and if I use session from you, how will I be able to implement login on my own? I know only a little bit about auth, I researched on web and using JWT and storing in a httponly cookie and doing refresh token implementation seems to be a good solution, I was wondering how that would go with supertokens, thanks.

If I were to implement user management (Login), when you guys introduce it for mongodb, will I be able to move users onto supertokens?

Again I'm sorry if the questions sound wrong.

Before I answer that question, one more question for you. Are you OK with using our managed service? Or do you definitely only want to use the self hosted version.

If you are OK with using the managed service, then you can use login + sessions since we store the data as well.

I think I'm okay with managed service as well since I'm planning to use it to a new side project

Sounds good! Then you can follow our quick setup and you should be able to use login + sessions out of the box. Now coming to your question about NextJS, do you have an API server too?

I'm planning to build it on serverless functions on Vercel

Using node under the hood?

Yeah I think

Do they allow you to add middlewares?

They have express like syntax but I'm not sure if they use express under the hood

Hmmmm.

That might be an issue then

Cause we work with express

If they are compatible with express, it should be fine
