Getting Started with Next.js SaaS Development

Building a SaaS application from scratch can be overwhelming. There are so many decisions to make: which framework to use, how to handle authentication, how to process payments, and more. In this guide, we'll walk through the essentials of building a production-ready SaaS with Next.js.

Next.js has become the go-to framework for building modern web applications, and for good reason:

• ✓Server-Side Rendering - Fast page loads and better SEO
• ✓API Routes - Build your backend right in your Next.js app
• ✓File-Based Routing - Intuitive and easy to understand
• ✓TypeScript Support - Catch errors before they reach production
• ✓Excellent Developer Experience - Hot reload, error overlays, and more

Every successful SaaS needs these core features:

▸1. Authentication

User authentication is the foundation of any SaaS. You need to:

• ✓Allow users to sign up and log in securely
• ✓Support OAuth providers (Google, GitHub, etc.)
• ✓Handle password resets and email verification
• ✓Manage user sessions

Recommended Solution: Supabase Auth provides all of this out of the box.

▸2. Database

Your SaaS needs to store user data, application data, and more. Consider:

• ✓PostgreSQL for relational data
• ✓Row Level Security (RLS) for multi-tenant isolation
• ✓Real-time subscriptions for live updates
• ✓Type-safe database queries

Recommended Solution: Supabase offers PostgreSQL with RLS and real-time features.

▸3. Payments

To monetize your SaaS, you need a payment system:

• ✓Subscription billing (monthly/annual)
• ✓Usage-based pricing
• ✓Trial periods
• ✓Billing portal for customers

Recommended Solution: Stripe handles all payment scenarios.

Here's how to get started with this boilerplate:

# Clone the repository
git clone https://github.com/yourusername/your-repo.git

# Install dependencies
npm install

# Copy environment variables
cp .env.local.example .env.local

# Run the development server
npm run dev

Your .env.local file should include:

# Supabase
NEXT_PUBLIC_SUPABASE_URL=your-supabase-url
NEXT_PUBLIC_SUPABASE_ANON_KEY=your-anon-key
SUPABASE_SERVICE_ROLE_KEY=your-service-role-key

# Stripe
NEXT_PUBLIC_STRIPE_PUBLISHABLE_KEY=your-publishable-key
STRIPE_SECRET_KEY=your-secret-key

Understanding the project structure helps you navigate and extend the boilerplate:

• ✓src/app/ - Next.js pages and API routes
• ✓src/components/ - Reusable UI components
• ✓src/features/ - Feature-specific components
• ✓src/lib/ - Utility functions and configurations
• ✓src/hooks/ - Custom React hooks
• ✓supabase/migrations/ - Database migrations

Now that you understand the basics, here's what to do next:

• ✓Customize the Landing Page - Edit src/config/site-config.ts
• ✓Set Up Your Database - Run npm run db:init
• ✓Configure Stripe Products - Create your pricing tiers
• ✓Deploy to Production - Use Vercel for one-click deployment

Building a SaaS doesn't have to be complicated. With the right tools and a solid foundation, you can launch your product in days instead of months. This boilerplate gives you everything you need to focus on what makes your SaaS unique.
