Environment variable management for Node.js

Reading configuration in Node.js

Access variables through process.env. Validate required keys at boot so misconfiguration fails loudly.

import { z } from 'zod';

const env = z
  .object({
    DATABASE_URL: z.string().url(),
    API_KEY: z.string().min(1),
  })
  .parse(process.env);

dotenv for local loads

Libraries like dotenv load a file into process.env for local development. In production, prefer platform injection or a pull from EANVI so machines do not depend on unchecked files.

Team sync with the Eanvi CLI

Bind a project environment with eanvi init, then eanvi pull before npm run dev. CI can authenticate with an API key and pull the staging or production set as needed.
