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.

Integrations allow you to:

• 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.

• JavaScript / Node.js — use varlock in custom toolchains, scripts, and servers.
• Next.js — drop-in replacement for @next/env.
• Vite — Vite plugin that validates and replaces at build time.
• Qwik — Use the Vite integration.
• React Router — Use the Vite integration.
• Cloudflare Workers — Use the Vite intregration + Cloudflare Vite plugin.
• Astro — Astro integration built on top of our Vite plugin.
• GitHub Actions — Validate your .env.schema in GitHub Actions workflows
• Other languages — guidance for piping varlock output into non-JS runtimes.
• Docker — A Docker wrapper around the varlock CLI including examples.

We’re actively working on additional first-party integrations for popular runtimes, frameworks and hosting platforms. If yours isn’t listed yet, let us know!
