SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill prevents runtime errors caused by missing or invalid environment variables in TypeScript applications by enforcing strict validation at startup.

Core Features & Use Cases

Startup Validation: Ensures all required environment variables are present and correctly typed before the application starts.
Centralized Schema: Defines environment variable schemas in a shared package, promoting consistency across a monorepo.
Type Safety: Eliminates direct process.env access, providing type-safe access to validated variables.
Use Case: In a new Node.js service, use this Skill to define and validate DATABASE_URL, NODE_ENV, and JWT_SECRET ensuring the application only starts with a valid configuration.

Quick Start

Use the zod-env skill to validate environment variables for your application.

FAQPage Schema

How do I validate environment variables in a TypeScript project at startup?▼

Validate environment variables at application startup by defining a Zod schema to check required variables and enforce type safety before the process starts. This prevents runtime errors caused by missing or invalid configuration in TypeScript projects.

What is the best way to manage environment variables across a Node.js monorepo?▼

Managing environment variables across a Node.js monorepo is best handled by centralizing Zod schema definitions in a shared package. This ensures configuration consistency and type-safe access to validated variables across all services.

Can I use Zod with dotenv for local environment variable configuration?▼

Yes, you can use Zod with dotenv for local environment variable configuration. The Skill utilizes dotenv to load local development variables and Zod schemas to validate them, ensuring applications only start with valid configurations.

How do I stop direct process.env access and enforce type safety in Node.js?▼

Stop direct process.env access by validating variables against a Zod schema and interacting exclusively with the resulting typed object. This eliminates untyped configuration access and provides strict type safety for variables like DATABASE_URL.

Does zod-env work for validating required environment variables like JWT_SECRET and NODE_ENV?▼

Yes, zod-env works for validating required environment variables like JWT_SECRET and NODE_ENV. It uses Zod schemas to ensure these variables are present and correctly typed before the application starts, preventing invalid configuration states.
