what kind of app

Nodejs server

can you share a minimal reproducible example?
this utilities app can read the variable just fine -

Can I simply read the environment variables this way?

Or is there another standard for reading them in the application?

the code looks fine, but are you trying to define it as a service variable, because thats not how it works

Hmm, I see. But is there a way to read it or to differentiate the REPLICAS within my application?

🥲

are you trying to define it as a service variable?

yes

thats not how it works, dont do that, and then it will work

To give you context, the same application has 4 replicas, but they are socket applications. I want to read my database with 1000 users and distribute 250 to each replica

Is there a way to differentiate my replicas at the service layer?

the replica id is a unique id given to each replica

Yes, that's why I would like to use this ID as a reference to distribute users among the replicas

now that i have told you why you are having trouble with that, and how to fix it, what is blocking you now?

Sorry, I still don't understand. How should I define it to be able to read the variable from the code?

you dont need to define it, and you shouldn't, you defining it is causing the variable to be empty

But I am simply trying to read it with process.env, without defining it. It was created by Railway itself, right?

yes

In that case, shouldn't it have a value in console.log?

it will when you remove it from your service variables

Hello @Brody , even though I didn't add the RAILWAYREPLICAID to the service variables, I still receive it as empty in my console.log

please provide a minimal reproducible example

Alright, I created a simple project with NestJS and a health check endpoint. In this endpoint, I included console.log(RAILWAYREPLICAID). I deployed the project on Railway with 4 replicas, but I never added RAILWAYREPLICAID to the service variables. Even so, I am receiving null in console.log.

send the repo please
