Integrations Overview

Varlock ships with official integrations that wire the CLI, runtime helpers, and framework-specific plugins together so your configuration is validated, type-safe, and protected everywhere it runs.

If you are working in a monorepo, start with the Monorepos guide for schema layout, root-level dependency overrides, and CI patterns before picking a per-framework integration below.

Integrations let you:

load and validate .env files automatically during dev and use them in CI/CD and production
inject config into your code at build or request time
enable runtime protections such as leak prevention, and log redaction
