tomodachi
A framework to quickly create microservices using asyncio (async / await) on Python 3, with built-in support for HTTP, Websocket connections, AWS SNS+SQS event based messaging and RabbitMQ / AMQP topic exchange pub/sub for optional intra-service communication.

Built on Python 3 and used for fast-paced development

Tomodachi is a tiny framework designed to be used for microservice development by giving services capabilities of listening on HTTP or communicating over event driven message buses like RabbitMQ, AMQP, AWS (Amazon Web Services) SNS+SQS, etc.

It's designed to be extendable to make use of any type of transport layer available.

Usage: tomodachi <command> [options] [arguments]

Options:
  -h, --help                                Show this help message and exit
  -v, --version                             Print tomodachi version
  --dependency-versions                     Print versions of dependencies

Available commands:
  ---
  Command: run
  Starts service(s) defined in the .py files specified as <service> argument(s)

  $ tomodachi run <service ...> [-c <config-file ...>] [--production]
  | --loop [auto|asyncio|uvloop]            Event loop implementation [asyncio]
  | --production                            Disable restart on file changes
  | -c, --config <files>                    Use configuration from JSON files
  | -l, --log <level>, --log-level <level>  Specify log level

Supported protocols / transport layers

tomodachi comes with some built-in triggers for your code, with the possibility to add additional subscriptions (ways of invoking service tasks / functions) by extending the tomodachi.Invoker class.

Currently available built-in supported protocols and transport methods:

HTTP requests – including connection keep-alive
WebSocket connections
AWS SNS + SQS event based messaging – incl. message attributes and filter policy support
RabbitMQ / AMQP pub/sub – topic exchange
Scheduled function invocations – with cron notation or on timed intervals
