​
Configuration Overview

PreLaunch uses a central configuration file to manage application settings. This makes it easy to customize your application without diving into the code. The main configuration file is config.ts in the root directory.

​
Core Configuration File

The config.ts file contains all the main settings for your application: 
// config.ts
import { ConfigProps } from "./types/config";

const config = {
  // REQUIRED
  appName: "PreLaunch",
  // REQUIRED: a short description of your app for SEO tags
  appDescription: "Focused on product validation phase, helping you quickly deploy a professional website, validate product ideas and collect potential user feedback.",
  // REQUIRED (no https://, not trailing slash at the end, just the naked domain)
  domainName: "prelaunch.online",
  
  // Other configuration sections...
} as ConfigProps;

export default config;

​
Main Configuration Sections

​
Basic Information

appName: "PreLaunch",
appDescription: "Your app description here",
domainName: "yourdomain.com",
These settings are used throughout the application for SEO tags, page titles, and metadata.

​
Customer Support (Crisp)

crisp: {
  // Crisp website ID. Set to empty string if you don't use Crisp
  id: "YOUR_CRISP_ID",
  // Hide Crisp by default, except on route "/". Crisp is toggled with <ButtonSupport/>
  onlyShowOnRoutes: ["/"],
},
PreLaunch integrates with Crisp for customer support chat. You can enable or disable it here.

​
Payment Configuration (Paddle)

paddle: {
  plans: [
    {
      priceId: "pri_01jrqpcg09vwepwkfxt1by8np3",
      id: "template",
      icon: "/assets/icons/paddle-icon.svg",
      features: ["Complete landing page template", "SEO optimization", "Waitlist functionality", "High performance loading", "User survey form", "Free updates", "Responsive design", "Source code access", "Dark mode support", "Developer support"],
      name: "Complete Package",
      description: "Get all features, one-time payment, lifetime access",
    },
    // Add more plans here
  ],
},
Configure your pricing plans, features, and Paddle price IDs here. Each plan should have a unique ID and a valid Paddle price ID.

​
Email Configuration (Resend)

resend: {
  // REQUIRED — Email 'From' field to be used when sending magic login links
  fromNoReply: `PreLaunch <noreply@prelaunch.online>`,
  // REQUIRED — Email 'From' field to be used when sending other emails, like abandoned carts, updates etc..
  fromAdmin: `Team at PreLaunch <team@prelaunch.online>`,
  // Support email shown to customer. Leave empty if not needed
  supportEmail: "support@prelaunch.online",
},
Configure your email sender information for transactional emails. PreLaunch uses Resend for email delivery.

​
Theme Configuration

colors: {
  // The DaisyUI theme to use. Leave blank for default (light & dark mode)
  theme: "",
  // This color will be reflected on the whole app outside of the document
  main: "#3b82f6",
},
Set your application theme and primary color here. PreLaunch uses DaisyUI for theming.

​
Authentication Configuration

auth: {
  // The path to log in users. Used to protect private routes
  loginUrl: "/api/auth/signin",
  // The path to redirect users after successful login
  callbackUrl: "/",
},
Configure your authentication routes and redirect URLs.

​
Environment Variables

In addition to the config.ts file, PreLaunch also uses environment variables for sensitive information. These should be set in your .env.local file: 
# Basic Configuration
NEXTAUTH_URL=http://localhost:3000
NEXTAUTH_SECRET=your_nextauth_secret

# Database (MongoDB)
MONGODB_URI=your_mongodb_uri

# Email (Resend)
RESEND_API_KEY=your_resend_api_key

# Paddle Payment
PADDLE_SANDBOX=true
PADDLE_API_KEY=your-api-key-here
PADDLE_NOTIFICATION_WEBHOOK_SECRET=your-webhook-secret-here
NEXT_PUBLIC_PADDLE_CLIENT_TOKEN=your-paddle-client-token-here

# Analytics
NEXT_PUBLIC_GA_MEASUREMENT_ID=your_ga_id

​
Creating a Custom Configuration Type

PreLaunch uses TypeScript for type safety. If you need to extend the configuration with new properties, you should update the ConfigProps type in types/config.ts: 
// types/config.ts
export interface ConfigProps {
  appName: string;
  appDescription: string;
  domainName: string;
  // Add your new properties here
  myCustomConfig?: {
    setting1: string;
    setting2: number;
  };
  // Other existing properties...
}

​
Best Practices

  • Keep Sensitive Information in Environment Variables: Never put API keys, secrets, or passwords in config.ts
  • Use Strong NEXTAUTH_SECRET: This value should be a long, random string to secure authentication
  • Review All Required Fields: Make sure all fields marked as “REQUIRED” are filled in
  • Use Development/Production Environments: Use different values for development and production environments
