Hmm i might drop some features like dotenv.

EDIT: Nevermind part 2, I should've tried harder. I just needed to install dotenv

// index.ts
import * as dotenv from "dotenv";

dotenv.config();

console.log(import.meta.env.SECRET);

That said, still running into some funkiness with a file that looks like the following:

// index.ts
import { someFunction } from "./someFunction"

someFunction()

// someFunction.ts
...

const thirdParty = new ThirdPartyClient({ auth: import.meta.env.AUTH_TOKEN })

function someFunction() {
  thirdParty.something(...)
}

The above won't work because import.meta.env.AUTH_TOKEN will be undefined. I needed to import and config dotenv in someFunction.ts in order for this work.

EDIT: Nevermind, I see you have to reference a specific value, like import.meta.env.SECRET. However, this still returns undefined with the following:

// .env
SECRET=hello

// index.ts
console.log(import.meta.env.SECRET)
// > undefined

Thank you for adding this in! Unfortunately, I'm trying to use this right now, and I'm still getting SyntaxError: Cannot use 'import.meta' outside a module. Am I using this incorrectly?

Just running yarn jiti index.ts where index.ts is just console.log(import.meta.env).

Yes, the way currently plugin works is that you need explicit import.meta.env.SOMETHING1 to be set. import.meta.env itself won't be transformed (we could support this btw..)
