Environment Setup

This guide details all the environment variables needed to run CONA and how to configure them for both the webapp and temporal workers.

Quick Start

Copy the example environment files from both apps:

# Copy webapp environment file
cp apps/webapp/.env.example apps/webapp/.env.local

# Copy temporal workers environment file
cp apps/temporal-workers/.env.example apps/temporal-workers/.env.local

Fill in the required variables in both .env.local files

Application Architecture

CONA consists of two main applications that require environment configuration:

Webapp (apps/webapp): Next.js application handling web UI, API routes, and integrations
Temporal Workers (apps/temporal-workers): Background workers processing workflows and long-running tasks

Both applications share some common environment variables but have specific requirements.

Webapp Environment Variables

Database Configuration

# PostgreSQL connection strings
DATABASE_URL="postgresql://postgres.user:password@pooler.supabase.com:6543/postgres?pgbouncer=true&sslmode=require"
DIRECT_URL="postgresql://postgres.user:password@pooler.supabase.com:5432/postgres?sslmode=require"

What these do:

DATABASE_URL: Main database connection using pgBouncer for connection pooling - optimized for high-throughput applications
DIRECT_URL: Direct database connection for migrations, schema changes, and operations requiring transaction isolation

Supabase Configuration

NEXT_PUBLIC_SUPABASE_URL="https://your-project.supabase.co"
NEXT_PUBLIC_SUPABASE_ANON_KEY="your-anon-key"

What these do:

NEXT_PUBLIC_SUPABASE_URL: Your Supabase project URL for database and auth services
NEXT_PUBLIC_SUPABASE_ANON_KEY: Public anonymous key for client-side Supabase operations (safe to expose)

Security & Encryption

ENCRYPTION_KEY="your-encryption-key"

What this does:

Encrypts sensitive data like API keys, tokens, and PII before storing in database
Generate using: openssl rand -base64 32
Must be the same across webapp and temporal-workers

Auth0 Configuration

AUTH0_DOMAIN="auth.your-app-url.com"
AUTH0_TENANT_DOMAIN="your-tenant.eu.auth0.com"
AUTH0_CLIENT_ID="your-client-id"
AUTH0_CLIENT_SECRET="your-client-secret"
AUTH0_SECRET="your-auth0-secret"
AUTH0_API_BASE_URL="https://your-tenant.eu.auth0.com/api/v2"
AUTH0_WEBHOOK_SECRET="your-webhook-secret"
AUTH0_M2M_CLIENT_ID="your-management-api-client-id"
AUTH0_M2M_CLIENT_SECRET="your-management-api-client-secret"

What these do:

AUTH0_DOMAIN: User-facing custom domain for login/signup flows (the branded URL users see, e.g. auth.cona.app)
AUTH0_TENANT_DOMAIN: Canonical tenant domain used only for the Management API v2 (e.g. your-tenant.eu.auth0.com). The Management API is not served on custom domains, so this must be the raw tenant host. If unset, the Management client falls back to parsing the hostname out of AUTH0_API_BASE_URL.
AUTH0_CLIENT_ID/SECRET: Application credentials for Auth0 SDK
AUTH0_SECRET: Random string for encrypting session cookies
AUTH0_API_BASE_URL: Management API endpoint for user management operations
AUTH0_WEBHOOK_SECRET: Validates webhook payloads from Auth0
AUTH0_M2M_CLIENT_ID/SECRET: Machine-to-machine credentials for server-side Auth0 operations

Application URLs

APP_BASE_URL="https://your-app-url.com"
NEXT_PUBLIC_APP_URL="https://your-app-url.com"

What these do:

APP_BASE_URL: Server-side base URL for redirects and API calls
NEXT_PUBLIC_APP_URL: Client-side accessible URL for frontend operations

Development & Debugging

DEV_PASSWORD="your-dev-password"

What this does:

Password-protects development routes and debugging tools in non-production environments

Vercel Environment Detection (Staging/Preview)

# Automatically provided by Vercel for Next.js projects (no setup required)
NEXT_PUBLIC_VERCEL_ENV="preview"  # or "production", "development"
NEXT_PUBLIC_VERCEL_TARGET_ENV="staging"  # custom environment name if configured

What these do:

NEXT_PUBLIC_VERCEL_ENV: The deployment environment (development, preview, or production)
NEXT_PUBLIC_VERCEL_TARGET_ENV: The custom environment name (e.g., staging) when using Vercel custom environments

Both variables are automatically provided by Vercel for Next.js projects as Framework Environment Variables. No manual setup required. Why this matters: Client-side components (like debug mode toggle) need the NEXT_PUBLIC_ prefix to access environment variables in the browser. The getEnvironmentInfo() utility uses these variables to detect the current environment on both server and client.

Integration APIs
