How can I run code during build?

I have a function that checks that the environment variables required by my app are correctly defined.
Currently that function runs inside a middleware which fails without giving any meaningful information unless you check the server logs.
I would like to call that function during the build instead, so that the build fails if the function finds missing env variables.
What would be the best way to accomplish this?

But if you already have an env var validation system and dont want to use t3-env, you can just import the logic to next.config.js

hmm, the only issue is that my env validation code is in TypeScript
not sure I can import from next.config.js…?
you have to use js and for typing,
// @ts-check with jsdoc i guessor you can also use a typescript file and run it before
next buildLarge oak-apple gallOP
how would I do that?
@Large oak-apple gall how would I do that?
use something like
ts-node then- "build": "next build",
+ "build": "ts-node utils/check-env.ts && next build"Large oak-apple gallOP
oh interesting, I'll look into it
so I assume there's no other built-in "post-build" hook in Next?
that would run in the same environment as the rest of your Next code
no there isn't anything like that
