Nextjs 15 standalone mode support

[riccardolardi]

Hi all. I'm trying to deploy a T3 standalone build on a VPS. Upon starting node server.ts I get a bunch of Invalid environment variables errors to T3 env being not able to find the variables. Is this a known issue? Is T3 not compatible with standalone mode?

I was having this issue, and what fixed for me was add transpilePackages: [ "@t3-oss/env-nextjs", "@t3-oss/env-core" ] to my next.config.mjs

Thanks, but this doesn't seem to work for me (same errors)

Sorry, it did indeed work - I just didn't check your code exactly, there was a typo so what worked for me is transpilePackages: [ "@t3-oss/env-nextjs"]

Maybe would be a good idea to include this in the docs?

You need to add the following to your next.config.ts:

transpilePackages: ["@t3-oss/env-nextjs", "@t3-oss/env-core"],
