Hello World micro API

[rnagulapalle]

Summary

Shipped a minimal single-file FastAPI service exposing a GET /hello endpoint that returns a JSON payload with a static greeting message and a dynamic UTC ISO-8601 timestamp. No database or authentication is required — this is a lightweight, container-ready micro API suitable as a service health probe or project scaffold.

Changes

• feat: Implemented app.py with a single GET /hello endpoint returning {"message": "hello world", "timestamp": ""} using a Pydantic response model and timezone-aware timestamps
• feat: Created Dockerfile and docker-compose.yml for containerized local development and deployment
• feat: Added requirements.txt with pinned dependencies: fastapi>=0.115.0 and uvicorn>=0.30.0
• docs: Created RUNNING.md with complete setup, run, and test instructions for both local and Docker workflows
• test: Added comprehensive test suite covering response status codes, JSON schema validation, ISO 8601 timestamp parsing with UTC timezone assertion, content-type headers, timing window checks, 404 for undefined routes, and 405 for disallowed HTTP methods

Testing

Full test suite executed via pytest using FastAPI's TestClient. Tests validate the response schema (exact key set, message value, ISO 8601 timestamp format, UTC timezone), correct HTTP status codes, content-type headers, and proper error responses for undefined routes (404) and wrong HTTP methods (405).

Running Locally

docker compose build

docker compose up -d

curl http://localhost:8000/hello

URL: http://localhost:8000
