envguard

The fastest way to make broken environment variables fail before your app does.

Why This Exists

Most apps trust process.env until something explodes in production. A missing DATABASE_URL or invalid PORT often fails late, far from startup. That means confusing runtime crashes, noisy logs, and slow debugging. You should know your environment is valid the moment your app boots.

The Fix

import { loadEnv } from "envguard";

const env = loadEnv({
  PORT: "number",
  DATABASE_URL: "string",
});
