check-env

Check that the critical environment variables are set for your app, and that you did not leave dangerous development overrides in production.

Installation

bun add @nitra/check-env

Usage

import checkEnv from '@nitra/check-env'

checkEnv(
  // Will log an error and throw if any of these are missing:
  [
    'SOME_API_SECRET',
    'PRIVATE_TOKEN',
    'SOME_OTHER_IMPORTANT_THING'
    // ...
  ]
)

If some required environment variable are not set, it will tell you and throw an error at the end:

SKIP_CHECK_ENV

If the SKIP_CHECK_ENV environment variable is set, the library will skip required variable checks and will not throw. This can be useful for local development or specific CI scenarios.

SKIP_CHECK_ENV=1 bun node app.js

• With SKIP_CHECK_ENV enabled, you'll see a warning in logs: SKIP_CHECK_ENV is set, skipping environment variable check.
• The exported env will behave like plain process.env (no proxy checks for prior validation).
