You deploy. The app starts. Then it dies because DATABASE_URL doesn't exist in production. envshield catches that before a single request is served.

Setup

Write a schema:

# .env.schema
DATABASE_URL=required
STRIPE_SECRET_KEY=required
PORT=3000
LOG_LEVEL=info

Then run:

npx @neocrev/envshield

If something's missing, you'll know immediately.

Integrations

# CI
- run: npx @neocrev/envshield --strict

COPY .env.schema ./
RUN npx @neocrev/envshield

# pre-commit hook
npx @neocrev/envshield --strict

Options

| Flag | Description | Default | |------|-------------|---------| | -s, --schema | Path to schema file | .env.schema | | -e, --env | Path to env file | .env | | -t, --strict | Fail on missing required fields | warn only | | -i, --init | Generate schema from .env.example | | | -h, --help | Show help | |
