Env Validator CLI

Validate required environment variables locally, in CI, and before production builds so missing secrets fail early.

Prerequisites

A Node.js project with npm scripts.
A list of required environment variables for each environment.
CI or deployment scripts where validation can run before build.

Install the CLI

Setup snippet

npm install -D @codersarts/env-validator

Create an environment schema

Setup snippet

{
  "DATABASE_URL": { "required": true, "type": "url" },
  "STRIPE_SECRET_KEY": { "required": true, "startsWith": "sk_" },
  "APP_URL": { "required": true, "type": "url" }
}

Add npm scripts

Setup snippet

"scripts": {
  "env:check": "env-validator --schema env.schema.json --file .env",
  "prebuild": "npm run env:check"
}

Wire validation into CI

Checklist

Run validation before tests and production builds.
Use environment-specific schema files when staging and production differ.
Fail the pipeline when required secrets are empty or malformed.
