Structure it using a layered architecture that separates routes, controllers, services, and repositories. This approach codifies clear responsibilities across Node.js Express TypeScript projects, establishing a consistent and scalable backend development approach.

The recommended directory layout enforces a structured organization for Node.js TypeScript services. It requires specific component conventions, including a shared BaseController, to maintain naming consistency and reusable patterns across the project.

Integrate Sentry error handling into Express TypeScript applications by applying integrated error handling patterns within your controllers and middleware. This provides robust observability tooling and reduces regressions across your backend services.

Refactor existing Node.js routes and controllers by auditing your project against established guidelines. Begin aligning routes, controllers, and services with the prescribed layered architecture to resolve architectural inconsistency.

Yes, you can use these backend guidelines for existing Express projects with inconsistent patterns. The guidelines provide migration playbooks and testing strategies specifically designed to reduce regressions while refactoring.
