# Lambda-IoT Core

This repository contains a minimal Go REST service used as the backend for the Lambda-IoT project.

Repository: https://git.piskot.si/SeminarM2/lambdaiot-core

## Features ✅

- Simple HTTP server with two endpoints:
  - `GET /health` — basic health check
  - `GET /hello` — example greeting endpoint
- Tests for handlers using `httptest`
- Multi-stage `Dockerfile` for small production images
- `Makefile` with common tasks (build, run, test, docker-build)

---

## Quickstart 🔧

Build and run locally:

```bash
make build
./bin/server
```

Run tests:

```bash
make test
```

Build Docker image:

```bash
make docker-build
```

Then run it:

```bash
docker run -p 8080:8080 lambdaiot-core:latest
```

### Endpoints

- `http://localhost:8080/health` — returns `{ "status": "ok" }`
- `http://localhost:8080/hello` — returns a small greeting JSON
- `POST http://localhost:8080/login` — demo login, JSON body: `{ "username": "admin", "password": "password" }`, returns `{ "token": "..." }`
- `GET http://localhost:8080/protected` — protected endpoint requiring `Authorization: Bearer <token>` header

### Environment

- `JWT_SECRET` — (optional) secret used to sign tokens; defaults to `secret` for local/dev use

If you want I can wire more features (structured logging, config, middleware, or dependency injection). Just tell me which direction to take. 🎯
