Server

An Event Server is composed by:

Component	Description
handler	Class that will receive and process the event
register	Class that will register the handler to Event Discovery
EventSchema	Event Schema will be accepted in the payload attribute

Example:

from events_protocol.server.handler.event_handler_registry import EventRegister
from events_protocol.core.builder import EventBuilder, Event
from events_protocol.core.model.base import CamelPydanticMixin
from events_protocol.core.model.event import Event, ResponseEvent
from events_protocol.server.handler.event_handler import EventHandler
from events_protocol.server.parser.event_processor import EventProcessor


class MyEventSchema(CamelPydanticMixin):
    example: str


class MyHandler(EventHandler):
    _SCHEMA = MyEventSchema

    @classmethod
    def handle(cls, event: Event) -> ResponseEvent:
        payload = cls.parse_event(event)
        response = {"MyEventPayload": payload.example}
        return EventBuilder.response_for(event, response)


class MyEventRegister(EventRegister):
    event_name = "get:event:example"
    event_version = 1
    event_handler = MyHandler


MyEventRegister.register_event()

event_input = Event(
    name="get:event:example",
    version=1,
    id="9230c47c-3bcf-11ea-b77f-2e728ce88125",
    flow_id="a47830ca-3bcf-11ea-a232-2e728ce88125",
    payload={
        "example": "example"
    },
    identity={
        "userId": "USER_ID",
    },
    metadata={
        "date": "00-00-0000",
    },
)
input_body = event_input.to_json()

response = EventProcessor.process_event(input_body)
