## What it is
Ts.ED is a TypeScript framework for Node.js and Bun built on top of Express.js, Koa.js, or Fastify.js, using decorators and class-based architecture to structure server-side applications. It includes dependency injection, routing, OpenAPI/JSON Schema support, a CLI for scaffolding, configuration sources, and 100+ plugins.

## Use cases
- build a REST API in TypeScript with decorators
- scaffold a Node.js backend project with a CLI
- generate OpenAPI/Swagger documentation from controllers
- build a serverless API on AWS with TypeScript
- add WebSocket endpoints to a TypeScript server
- use dependency injection in a Node.js application
- migrate between Express, Koa, and Fastify platforms

## When to choose
- you want a NestJS-like decorator-based framework with a lighter learning curve
- you need OpenAPI/Swagger docs generated from your code
- you want flexibility to switch between Express, Koa, and Fastify
- you prefer class-based controllers, models, and DI in TypeScript

## When to avoid
- you prefer minimal, unopinionated frameworks without decorators
- your project is plain JavaScript without TypeScript
- you need a framework with a much larger ecosystem and community than NestJS
