## Overview

This is a minimal NestJS starter application, not the NestJS framework itself. Its runtime starts the AppModule, which registers one GET endpoint; the controller delegates to a service that returns a fixed greeting. The README describes the starter and framework generally, but the sampled application source establishes only this endpoint. The HTTP transport details are provided by NestJS and are not mapped as repository components.

Main entry points: [`src/app.controller.ts`](https://github.com/abdulloh8085/nestar/blob/master/src/app.controller.ts) (App controller), [`src/app.module.ts`](https://github.com/abdulloh8085/nestar/blob/master/src/app.module.ts) (App module), [`src/app.service.ts`](https://github.com/abdulloh8085/nestar/blob/master/src/app.service.ts) (App service), [`src/main.ts`](https://github.com/abdulloh8085/nestar/blob/master/src/main.ts) (Bootstrap)
