🎯 Usage Examples

Accessing Configuration

src/config/index.ts

import { appConfig } from "@/config";

// Access metadata
const siteName = appConfig.metadata.name;
const siteTitle = appConfig.metadata.title;

// Access theme settings
const themeEnabled = appConfig.ui.theme.enabled;
const defaultMode = appConfig.ui.theme.defaultMode;

// Access payment plans
const allPlans = appConfig.payment.plans;
const nextjsPlan = appConfig.payment.plans.nextjs;

Type Safety

The configuration is fully typed with TypeScript:

src/config/index.ts

import type { AppConfig } from "@/config/types";

// Configuration is type-safe
const config: AppConfig = {
  // TypeScript will enforce correct structure
};

📝 Best Practices

Environment Variables: Use environment variables for sensitive data like API keys and price IDs
Type Safety: Always use the provided TypeScript types
Consistent Naming: Follow the existing naming conventions
Documentation: Update this documentation when adding new configuration options
Validation: Consider adding runtime validation for critical configuration values

🔧 Customization

To customize the configuration:

Edit the config file: Modify src/config/index.ts
Update types: Add new types to src/config/types.ts if needed
Use throughout app: Access configuration via import { appConfig } from "@/config"
Environment variables: Use .env files for environment-specific values

Your NEXTDEVKIT application configuration is now properly documented and ready for customization! 🎉
