Tech Stack

Getting Started

Prerequisites

  • Node.js 18.17.0 or later
  • pnpm (recommended) or npm/yarn
  • Upstash Redis account (for production)

Installation

  1. Clone the repository:

    git clone https://github.com/vercel/platforms.git
cd platforms

  2. Install dependencies:

    pnpm install

  3. Set up environment variables: Create a .env.local file in the root directory with:

    KV_REST_API_URL=your_redis_url
KV_REST_API_TOKEN=your_redis_token

  4. Start the development server:

    pnpm dev

  5. Access the application:

Multi-Tenant Architecture

This application demonstrates a subdomain-based multi-tenant architecture where:

  • Each tenant gets their own subdomain (tenant.yourdomain.com)
  • The middleware handles routing requests to the correct tenant
  • Tenant data is stored in Redis using a subdomain:{name} key pattern
  • The main domain hosts the landing page and admin interface
  • Subdomains are dynamically mapped to tenant-specific content

The middleware (middleware.ts) intelligently detects subdomains across various environments (local development, production, and Vercel preview deployments).

Deployment

This application is designed to be deployed on Vercel. To deploy:

  1. Push your repository to GitHub
  2. Connect your repository to Vercel
  3. Configure environment variables
  4. Deploy

For custom domains, make sure to:

  1. Add your root domain to Vercel
  2. Set up a wildcard DNS record (*.yourdomain.com) on Vercel
