Why EnvGuard?

Stop worrying about missing or invalid environment variables in production

Runtime Validation

Validate environment variables at runtime using your Zod schema

Catch configuration errors early and prevent silent failures in production.

Type Safety

Get full TypeScript support with inferred types from your schema

Enjoy autocomplete and type checking for all your environment variables.

Zero Config

Simple API that works with your existing Zod schemas

No complex setup required. Define your schema and you're ready to go.

Simple to Use

Define your schema and let EnvGuard handle the rest

config.ts

import { z } from 'zod'
import { loadDotEnv } from 'envguard'

const envSchema = z.object({
  DATABASE_URL: z.string().url(),
  API_KEY: z.string().min(1),
  PORT: z.coerce.number().default(3000),
  NODE_ENV: z.enum(['development', 'production', 'test'])
})

export const env = loadDotEnv(envSchema)

console.log(env.DATABASE_URL)
console.log(env.PORT)
console.log(env.API_KEY)
