Is there an easy way to share a session on 2 localhost front

Question

Is there an easy way to share a session on 2 localhost frontends on 2 different ports e g localhost 8080 and localhost 9000

rp · Answer

I think this should happen by default

rp · Answer

Are the backends for both different or the same

constantinos · Answer

The same

rp · Answer

right So i think this should work without you having to do anything

constantinos · Answer

But in the api I am selecting a port

rp · Answer

the websiteDomain value on the backend should be either one of the frontend domains depending on which one you show the auth UI on

rp · Answer

and the websiteDomain on the frontend should be as per what that frontend is loaded on localhost 8080 or localhost 9000

constantinos · Answer

Ok let me try

constantinos · Answer

On the front ends I am not using `websiteDomain` I am using with Vue

constantinos · Answer

Should I

rp · Answer

ah i see

rp · Answer

no that s fine

rp · Answer

i thought you were using supetokens auth react SDK

constantinos · Answer

I first create the session on localhost 8080 Then try to visit http editor localhost 9001 and the session is not shared Is it because of the subdomain

rp · Answer

ah yea sub domain indeed

rp · Answer

try this https supertokens com docs thirdpartyemailpassword common customizations sessions share sessions across sub domains

rp · Answer

but im not sure if it s gonna work cause you are using localhost But give it a try anyway

rp · Answer

set the `sessionScope` to ` localhost`

constantinos · Answer

It works without the subdomain but not with it

rp · Answer

yeaaa Cause you are using localhost on the frontend I don t think putting a localhost is a valid cookieDomain browser may reject it

rp · Answer

so maybe use something other than localhost like a proper domain and change your PC s hosts file to redirect it to localhost

constantinos · Answer

How would I distinguish between the ports I can only set 127 0 0 1 not a port I am on windows

rp · Answer

i don t think IP addresses would work either

rp · Answer

you will have to give a proper domain name

constantinos · Answer

Getting this error in the backend `Error Please make sure that the apiDomain and websiteDomain have correct values`

rp · Answer

Can you print out the value of websiteDomain and apiDomain

constantinos · Answer

Yes

rp · Answer

What is the stack trace of the error

constantinos · Answer

What do you mean

rp · Answer

The full error not just the message part of it

constantinos · Answer

It works only if I change it back to localhost

constantinos · Answer

Do I need to do anything s ecial to run a custom host with nodemon

rp · Answer

this is weird Give me a min

rp · Answer

right So onrender com is a special domain name it s in the public suffix list https publicsuffix org

rp · Answer

So the domain you have provided with onrender com is actually inaccurate

rp · Answer

if you provide the correct domain values as given by onrender com when you sign up on their site it should be fine

constantinos · Answer

I see thanks

constantinos · Answer

Now getting connection refused Is it because I am on http

rp · Answer

Connection refused is cause the server is not running or some firewall setting issue Nothing to with supertokens setup

constantinos · Answer

I tried to disable windows defender and its the same The api is definetely running

rp · Answer

Can you use postman to query that api What does it return

rp · Answer

This is a DNS lookup error This is something you will have to fix yourself Nothing to do with ST
