jararaca 0.1.2

A simple and fast API framework for Python

Jararaca Microservice Framework

Overview

Jararaca is a aio-first microservice framework that provides a set of tools to build and deploy microservices in a simple and clear way.

Features

Hexagonal Architecture

The framework is based on the hexagonal architecture, which allows you to separate the business logic from the infrastructure, making the code more testable and maintainable.

Dependency Injection

The framework uses the dependency injection pattern to manage the dependencies between the components of the application.

Web Server Port

The framework provides a web server that listens on a specific port and routes the requests to the appropriate handler. It uses FastAPI as the web framework.

Message Bus

The framework provides a message bus that allows you to send messages between the components of the application. It uses AIO Pika as the message broker worker and publisher.

Installation

pip install jararaca

Usage

Create a Microservice

# app.py
from jararaca import Microservice, create_http_server, create_messagebus_worker

app = Microservice(
    providers=[
        ProviderSpec(
            provide=Token[AppConfig],
            use_factory=AppConfig.provider,
        )
    ],
    controllers=[TasksController],
    interceptors=[
        AIOSqlAlchemySessionInterceptor(
            AIOSQAConfig(
                connection_name="default",
                url="sqlite+aiosqlite:///db.sqlite3",
            )
        ),
    ],
)

web_app = create_http_server(app)
messagebus_worker = create_messagebus_worker(app)

Run as a Web Server

uvicorn app:web_app --reload

Run as a Message Bus Worker
