Why Node.js?

Node.js lets you write backend in JavaScript and TypeScript. One language, one team, one ecosystem. This simplifies communication, speeds up development, and lowers costs. For us, Node.js is a natural choice because our entire stack speaks the same language.

What Node.js gives you

  • I/O performance

    Event-driven, non-blocking I/O. Handles thousands of concurrent connections without spawning new threads.

  • One language

    TypeScript on frontend and backend. Smaller team, shared types, faster development.

  • npm ecosystem

    The largest package registry in the world. A proven solution for every problem.

  • Scalability

    From prototype to millions of users. Clustering, load balancing, microservices.

How we work with Node.js

Node.js powers our backend: Next.js API routes, Server Actions, and external integrations.

  • API and Server Actions

    • Next.js API routes for REST endpoints
    • Server Actions for data operations
    • Middleware for authentication and rate limiting
  • External integrations

    • Email delivery (transactional and marketing)
    • Webhooks and SaaS integrations
    • Supabase Edge Functions
  • Tools and automation

    • Migration scripts and seeders
    • CI/CD pipeline with GitHub Actions
    • Type generation and build tools
