Environment Variables

ShipKit uses T3 Env for type-safe environment variable validation, ensuring runtime safety and excellent TypeScript integration.

Quick Setup

Copy the example environment file:

cp .env.example .env.local

Generate required secrets:

# Generate AUTH_SECRET
openssl rand -base64 32

Required Variables

Core Authentication

# Base URL for authentication
# In production, this will be automatically set to VERCEL_URL
AUTH_URL="http://localhost:3000"

# JWT secret for session management
# Generate with: openssl rand -base64 32
AUTH_SECRET=""

OAuth Providers (Optional)

# GitHub OAuth
AUTH_GITHUB_ID=""
AUTH_GITHUB_SECRET=""

# Discord OAuth
AUTH_DISCORD_ID=""
AUTH_DISCORD_SECRET=""

# Google OAuth
AUTH_GOOGLE_ID=""
AUTH_GOOGLE_SECRET=""

Database

# PostgreSQL connection string
DATABASE_URL="postgresql://postgres:password@localhost:5432/shipkit"

# Database prefix (defaults to "db")
DB_PREFIX="db"

External Services (Optional)

GitHub Integration

# GitHub access token for repo operations
GITHUB_ACCESS_TOKEN=""

Google Services

# Google service account credentials
GOOGLE_CLIENT_EMAIL=""
GOOGLE_PRIVATE_KEY=""

AI Services

# OpenAI API key
OPENAI_API_KEY=""

# Anthropic API key
ANTHROPIC_API_KEY=""

Payments

# LemonSqueezy credentials
LEMONSQUEEZY_API_KEY=""
LEMONSQUEEZY_STORE_ID=""

Node Environment

# Node environment (defaults to "development")
# Values: development, test, production
NODE_ENV="development"

Type Safety

Environment variables are validated using T3 Env and Zod schemas:

// src/env.ts
import { createEnv } from "@t3-oss/env-nextjs";
import { z } from "zod";

export const env = createEnv({
  server: {
    DATABASE_URL: z.string().url().optional(),
    DB_PREFIX: z.string().default("db"),
    NODE_ENV: z.enum(["development", "test", "production"]).default("development"),

    // Auth
    AUTH_SECRET: z.string().optional(),
    AUTH_URL: z.preprocess(
      (str) => process.env.VERCEL_URL ?? str,
      process.env.VERCEL ? z.string().optional() : z.string().url().optional(),
    ),
    AUTH_DISCORD_ID: z.string().optional(),
    AUTH_DISCORD_SECRET: z.string().optional(),
    AUTH_GITHUB_ID: z.string().optional(),
    AUTH_GITHUB_SECRET: z.string().optional(),
    AUTH_GOOGLE_ID: z.string().optional(),
    AUTH_GOOGLE_SECRET: z.string().optional(),

    // GitHub
    GITHUB_ACCESS_TOKEN: z.string().optional(),

    // Google
    GOOGLE_CLIENT_EMAIL: z.string().optional(),
    GOOGLE_PRIVATE_KEY: z.string().optional(),

    // AI Services
    OPENAI_API_KEY: z.string().optional(),
    ANTHROPIC_API_KEY: z.string().optional(),

    // Payments
    LEMONSQUEEZY_API_KEY: z.string().optional(),
    LEMONSQUEEZY_STORE_ID: z.string().optional(),
  },
});

Environment Management

Local Development

Copy the example environment file:

cp .env.example .env.local

Update variables in .env.local

Production (Vercel)

Add variables through the Vercel dashboard or CLI:

vercel env add MY_VAR

After adding variables, redeploy your application:

vercel --prod
