Setting Up Your Tech Stack

Architecture Planning

Before diving into templates, establish your SaaS architecture foundation:

Frontend Considerations:

• Choose between SPA (React, Vue, Angular) or traditional server-rendered approaches
• Consider static site generation for marketing pages
• Plan for mobile responsiveness and PWA capabilities

Backend Decisions:

• API-first design for future mobile apps or integrations
• Database selection (PostgreSQL for complex queries, MongoDB for flexibility)
• Authentication strategy (Auth0, Firebase Auth, or custom JWT)

Infrastructure Choices:

• Cloud provider selection (AWS, Google Cloud, or Vercel/Netlify for simplicity)
• CDN setup for global performance
• Backup and disaster recovery planning

Customizing and Extending Templates

```
