create-envguard

Scaffold envguard into any Node.js project in one command.

Quick Start

npx create-envguard

That's it. The interactive wizard will:

1. Detect your framework (Next.js, NestJS, Vite, Express, or plain Node)
2. Ask about Docker/Kubernetes usage
3. Install the right @stacklance/envguard-* packages
4. Create env.schema.ts with framework-appropriate defaults
5. Create .env.example from your existing .env
6. Add env-guard check to your predev and prebuild scripts
7. Add .env to .gitignore

Framework-Specific Setup

Next.js

npx create-envguard --framework next

Creates a schema with NEXT_PUBLIC_* pattern support.

NestJS

npx create-envguard --framework nestjs

Installs @stacklance/envguard-nestjs and creates a schema with PORT and DATABASE_URL.

Vite

npx create-envguard --framework vite

Creates a schema with VITE_* prefix support.

Express

npx create-envguard --framework express

Plain Node.js

npx create-envguard --framework node

Non-Interactive Mode

Use the add subcommand to skip prompts:

npx create-envguard add
npx create-envguard add --framework next
npx create-envguard add --framework nestjs --docker --k8s
