Building Scalable Backends with Node.js and TypeScript
An exploration into structuring modern enterprise APIs. In this post, I dive deep into architectural patterns, static typing benefits, and how to maintain high performance.
When engineering high-performance APIs, the choice of stack and structure plays a critical role in long-term maintainability. Transitioning from plain JavaScript to TypeScript has become the industry standard for a reason: it catches bugs at compile time rather than runtime.
Structuring the Application
I usually recommend a layered architecture. Separating controllers, services, and data-access layers ensures that your business logic isn't tightly coupled to the Express or Fastify routing mechanism.
