Introduction

This repository is maintained by me, Anton Bolychev, for educational purposes, specifically for the Async Architecture course.

Repository Overview

This repository is organized into multiple microservices, designed as API-only applications. The microservices included are:

• Auth Service
• Task Tracker

The primary programming language is Python, with Postgres as the database and Nats Jetstream serving as the message broker.

The project heavily relies on the following Python packages:

• FastAPI: A web framework for building APIs with Python 3.8+, utilizing standard Python type hints.
• FastStream simplifies the creation of producers and consumers for message queues, providing automatic parsing, networking, and documentation generation.
• SQLModel is a library for interacting with SQL databases from Python code, with Python objects and designed to be compatible with FastAPI, Pydantic, and SQLAlchemy.

These packages are well-integrated between each other, allowing the main logic to be written in a single file and the application to be launched with a single command:

cd servicename/app
uvicorn --port=YOUR_PORT main:api --reload

Auth Service

The Auth Service implements authentication using JWT tokens.

• auth/: The primary directory for the Auth Service.
  • auth/app/main.py: The main application file containing the core logic.
  • auth/auth: Directory containing configurations, database models, password hashing functions, and request schemas.

Task Tracker

The Task Tracker manages tasks and their tracking.

• tasktracker/: The primary directory for the Task Tracker.
  • tasktracker/app/main.py: The main application file with the core logic.
  • tasktracker/tasktracker/: Directory containing configurations and database models.

Common Library

A separate library is included to provide shared functionality across all services. Currently, it is utilized for authorization and decoding JWT tokens.

• common/common/authorizer.py: The single file in the common library responsible for authorization.
