• Validation: Validates all environment variables on load
• MCP Configuration: Configuration management for MCP servers
• RevealUI Config: RevealUI-specific configuration

Installation

pnpm add @revealui/config

Usage

Load Environment Configuration

import { loadConfig } from '@revealui/config'

// Load and validate environment variables
const config = loadConfig()

// Access validated config
console.log(config.database.url) // Type-safe access
console.log(config.stripe.secretKey)
console.log(config.vercel.token)

RevealUI Configuration

import { getRevealUIConfig } from '@revealui/config/revealui'

const config = getRevealUIConfig()
// Returns validated RevealUI configuration

MCP Configuration

import { getMCPConfig } from '@revealui/config/mcp'

const mcpConfig = getMCPConfig()
// Returns MCP server configuration

Environment Variables

The config package validates these environment variables:

Required Variables

# Database
POSTGRES_URL=postgresql://user:password@host/database

# RevealUI
REVEALUI_SECRET=your_secret_key_here
REVEALUI_PUBLIC_SERVER_URL=http://localhost:4000

Optional Variables

# Stripe
STRIPE_SECRET_KEY=sk_test_...
STRIPE_WEBHOOK_SECRET=whsec_...

# Vercel
VERCEL_API_KEY=vercel_...
BLOB_READ_WRITE_TOKEN=vercel_blob_...

# Neon
NEON_API_KEY=neon_...

# Supabase
SUPABASE_URL=https://....supabase.co
SUPABASE_ANON_KEY=eyJ...
SUPABASE_SERVICE_ROLE_KEY=eyJ...

File Loading Priority

Environment variables are loaded in this order (later overrides earlier):

1. System environment variables
2. .env (shared defaults, if present)
3. .env.local (local overrides)
4. .env.development.local (development mode)
5. .env.production.local (production mode)

Validation

The package uses Zod schemas to validate configuration:

import { loadConfig } from '@revealui/config'

try {
  const config = loadConfig()
  // Config is valid and type-safe
} catch (error) {
  // Validation failed - missing or invalid variables
  console.error('Configuration error:', error)
}
