gen-env-types

Takes your .env file as input

SESSION_SECRET=asdjpfowqip
STRIPE_ACCESS_TOKEN=qoi120wqe

And generates a .d.ts file

declare namespace NodeJS {
  export interface ProcessEnv {
    SESSION_SECRET: string;
    STRIPE_ACCESS_TOKEN: string;
  }
}

Now process.env.SESSION_SECRET will autocomplete and be type-safe.

Usage

npx gen-env-types path/to/.env
