DESCRIPTION

This Moose::Role helps to quicly bootstrap async http service that is including OpenAPI documentation.

See https://time.meon.eu/ and Async::Microservice::Time code.

To bootstrap new async service

Create new package for your APIs from current examples lib/Async/Microservice/*. Inside set return value of service_name. This string will be used to set process name and to read/locate OpenAPI yaml definition for the documentation. Any GET/POST processing funtions must be defined in get_routes funtion.

Copy one of the bin/*.psgi update it with your new package name.

Copy one of the root/static/*.yaml to have the same name as service_name.

Now you are able to lauch the http service with:

    plackup -Ilib --port 8089 --server Twiggy bin/async-microservice-YOUNAME.psgi

In your broser you can read the OpenAPI documentation: http://0.0.0.0:8089/v1/ and also use editor to extend it: http://0.0.0.0:8089/v1/edit

TODO

    - graceful termination (finish all requests before terminating on sigterm/hup)
    - systemd service file examples
    - static/index.html and static/edit.html are not really static, should be moved
