ExpressoTS is a lightweight TypeScript framework for Node.js for building scalable server-side applications with clean architecture, a built-in DI container, controllers, use cases, and providers. It ships with a scaffolding CLI, an Express adapter, interceptors, type-safe events, guards, lazy loading, and a local developer experience platform called Studio.

Use cases

• build a REST or GraphQL API in TypeScript on Node.js
• scaffold a new backend service with clean architecture
• add role-based access control to API routes
• decouple domain logic with a type-safe event bus
• speed up cold starts with lazy-loaded modules
• inspect requests, logs, and DI graph locally during development
• build a tiny serverless HTTP service without a DI container

When to choose

• you want a NestJS-like structured TypeScript framework that is lighter weight
• you value clean architecture patterns (controllers, use cases, repositories) out of the box
• you want built-in DI, interceptors, events, and guards without assembling libraries yourself
• you want local observability tooling (Studio) during development

When to avoid

• you need the massive ecosystem and community of Express, Fastify, or NestJS
• you are building a minimal service and don't want framework conventions
• your team is not using TypeScript
• you require long-term enterprise-grade support guarantees from a large vendor
