Asynchronous Server Application Boilerplate

Asynchronous Server App Boilerplate (ASAB) is an open-source microservice platform for Python 3.7+ and asyncio. ASAB aims to minimize the amount of code that needs to be written when building a microservice or an application server. ASAB is fully asynchronous using async/await syntax from Python 3, making your code modern, non-blocking, speedy, and hence scalable. We make every effort to build ASAB container-friendly so that you can deploy ASAB-based microservices via Docker or Kubernetes swiftly and easily.

Anyone can (and is encouraged to) use ASAB in their own projects, for free.

ASAB is the right choice when:

You want to build a microservice or an application server

You are using Python 3.7+

You want to use asynchronous I/O

You want to write non-blocking, speedy, and scalable code

Here is a complete example of a working microservice:

hello_world.py

import asab

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

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