@ronanru is attempting to deploy a commit to the t3-oss Team on Vercel.

A member of the Team first needs to authorize it.

How useful really is this (ts config) considering the cjs limitations?

How useful really is this (ts config) considering the cjs limitations?

I don't like seeing js files in my src folder. With ts next config env.js can be env.ts. I don't think it changes anything else.

next.config.ts should be more useful in create-t3-turbo. I think we can remove jiti dependency there, when we update to next 15 there.

Are you sure this works? t3-env is an ESM only package which is called out to be incompatible

[ronanru]

Are you sure this works?

I tried multiple configurations, everything seems to work. Dev, Build, LSP all work. I get an error for missing env variables.

[juliusmarminge]

Try doing something esm in it, it will crash

This works:

// app/env.js
import { createEnv } from "@t3-oss/env-nextjs";
import { vercel } from "@t3-oss/env-nextjs/presets"
import { z } from "zod";

console.log(import.meta.filename)

export const env = createEnv({
  extends: [vercel()],
  server: {
    FOO: z.string()
  },
  experimental__runtimeEnv: {
    FOO: "bar"
  }
});

// next.config.js
import "./app/env.js"

export default {
  /* config options here */
};

Change file extensions to .ts. It crashes:

[ronanru]

oh, ok. I reverted the next config changes. We can add them later when the ESM thing is fixed.

[juliusmarminge]

we could have it like turbo and use jiti to load the ts file ?

Hey t3-oss/translators!

This PR contains changes to your language. Please review the changes ❤️.

[juliusmarminge]

I made some more changes to get it more in line with Next Auth v5 standards.

I did some manual testing but would be nice with some more before merging. Can you look it over again @ronanru and make sure my additions are all good?

[TheCukitoDev]

Can @t3dotgg @c-ehrlich and @nexxeln please review the code please?? I think it would be useful to have it implemented already

[ronanru]

Just tested your changes, everything looks good @juliusmarminge
