How To

To listen and dispatch events is very simple:

from onany import dispatch, listener

@listener("event.name")
def on_event_name(*args, **kwargs):
    print("I've been called with {} and {}".format(
        args,
        kwargs
    ))

>>> dispatch(
    "event.name",
    "first_param",
    "second_param",
    "third_param",
    first="param",
    second="param",
    third="param")

Should I wait all callbacks to end ?

Nope. You can “threadily” dispatch your events so they don’t need to be waited for the main process.

from onany import disthread, listener

@listener("event.name")
def on_event_name():
    print("I'm gonna be executed on another thread")

>>> disthread("event.name")

Webhook listener

It’s possible declare webhook rules to be dispatched as an inside event. This webhook events can be a powerful tool for communicating to third-party clients that an event is ended.

Listener rules:

• route

  • type: str

  • description: API route

  • required

• callback

  • type: callable/function

  • description: Receives request response object if needed

When dispatch or disthread is called is possible define some attributes to be sent in the external API call.

Attributes:

• data

  • type: dict

  • description: JSON body

• headers

  • type: dict

  • description: Dictionary declaring headers to be sent

Example:

from onany import dispatch, listener

def event_name_webhook_response(response):
    if response.status_code == 200:
        print("My hook listener worked")

listener("event.name", {
    "route": "https://my.api/hooks",
    "callback": event_name_webhook_response
})

>>> dispatch("event.name", data={
    "some": "payload",
    "I": "wanna",
    "send": "to",
    "hooked": "api"
})
