Jararaca Microservice Framework
Overview
Jararaca is an async-first microservice framework designed to simplify the development of distributed systems. It provides a comprehensive set of tools for building robust, scalable, and maintainable microservices with a focus on developer experience and type safety.
Key Features
REST API Development
- Easy-to-use interfaces for building REST APIs
- Automatic request/response validation
- Type-safe endpoints with FastAPI integration
- Automatic OpenAPI documentation generation
Message Bus Integration
- Topic-based message bus for event-driven architecture
- Support for both worker and publisher patterns
- Built-in message serialization and deserialization
- Easy integration with AIO Pika for RabbitMQ
Distributed WebSocket
- Room-based WebSocket communication
- Distributed broadcasting across multiple backend instances
- Automatic message synchronization between instances
- Built-in connection management and room handling
Task Scheduling
- Cron-based task scheduling
- Support for overlapping and non-overlapping tasks
- Distributed task execution
- Easy integration with message bus for task distribution
TypeScript Integration
- Automatic TypeScript interface generation
- Command-line tool for generating TypeScript types
- Support for REST endpoints, WebSocket events, and message bus payloads
- Type-safe frontend-backend communication
@ExposeTypedecorator - Explicitly expose types for TypeScript generation without needing them in endpoints
Hexagonal Architecture
- Clear separation of concerns
- Business logic isolation from infrastructure
- Easy testing and maintainability
- Dependency injection for flexible component management
Observability
- Built-in OpenTelemetry integration
- Distributed tracing support
- Logging and metrics collection
- Performance monitoring capabilities
Quick Start
Installation
pip install jararaca
Basic Usage
from jararaca import Microservice, create_http_server
from jararaca.presentation.http_microservice import HttpMicroservice
# Define your microservice
app = Microservice(
providers=[
# Add your providers here
],
controllers=[
# Add your controllers here
],
interceptors=[
# Add your interceptors here
],
)
# Create HTTP server
http_app = HttpMicroservice(app)
web_app = create_http_server(app)
Running the Service
# Run as HTTP server
jararaca server app:http_app
# Run as message bus worker
jararaca worker app:app
# Run as scheduler
jararaca scheduler app:app
# Generate TypeScript interfaces
jararaca gen-tsi app.main:app app.ts
