## Features

- **`OpraHttpNestjsAdapter`** — NestJS adapter integrating OPRA's HTTP handler
- **`OpraExceptionFilter`** — Global exception filter that maps OPRA errors to HTTP responses
- **`OpraMiddleware`** — Request/response middleware for the OPRA pipeline
- Full support for NestJS **dependency injection**, **interceptors**, and **guards**

npm install @opra/nestjs-http
