## What it is
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
