ASAB simplifies a development of async application servers

Asynchronous Server App Boilerplate (or ASAB for short) minimizes the amount of code that needs to be written when building a server application in Python. ASAB is fully asynchronous, this means you can use the new shiny async/await syntax from Python 3.5, making your code non-blocking, speedy and hence scalable.

We hope you will find ASAB fun and easy to use, especially when you are about to build a Python-based application server such as web server, MQTT server, microservice container, ETL or stream processor.

ASAB is developed on GitHub.

Contributions are welcome.

Have fun!

Installation

pip install asab

Example

#!/usr/bin/env python3
import asab

class MyApplication(asab.Application):
    async def main(self):
        print("Hello world!")
        self.stop()

if __name__ == '__main__':
    app = MyApplication()
    app.run()

Principles

• Write once, use many times

• Keep it simple

• Well documented

• Asynchronous via Python 3.5+ async/await and asyncio

• Event-driven Architecture / Reactor pattern

• Single-threaded core but compatible with threads

• Good support for containerization

• Compatible with pypy, Just-In-Time compiler capable of boosting Python code performace more then 5x times

• Support for introspection

• Modularized

High-level architecture
