Asyncslackevent

Async SlackEvent server handler based on https://github.com/slackapi/python-slack-events-api

The AsyncSlack Events is an Async version of the Python-based solution of python-slack-events-api to receive and parse events from Slack’s Events API. Therefore, it works in the same manner as python-slack-events-api by using an Async event emitter attaching functions to event listeners.

It can serve your app by creating a Quart server or it can uses your own serer framework. The app uses Pint (openapi for Quart), however I couldnt manage to construct the code in order to use the openapi features and use at the same time the same structure as python-slack-events-api, so, for now, it creates creates routes as usually when using Quart:

@app.route("/", methods=['GET', 'POST'])
async def events():
    if request.method == 'GET':
        # If a GET request is made, return 404.
        print("GET RECEIVED!!!")
        return await make_response(
            "These are not the slackbots you're looking for.", 404)

Create a Slack Event Adapter for receiving actions via the Events API

---

Using the built-in Quart server:

from asyncslackevent import AsyncSlackEventAdapter

# Use AsyncSlackEventAdapter to start a Quart/Pint Server and handle the EventsAPI
app_server = AsyncSlackEventAdapter(SLACK_SIGNING_SECRET, "/slack/events")


# Create an event listener for "reaction_added" events and print the emoji name
@app_server.on("reaction_added")
async def reaction_added(event_data):
  emoji = event_data["event"]["reaction"]
  print(emoji)


# Start the server on port 3000
app_server.run(port=3000)

Using your existing Flask instance:

from quart import Quart
from asyncslackevent import AsyncSlackEventAdapter


# This `app` represents your existing Quart app
app = Quart(__name__)


# An example of one of your Quart app's routes
@app.route("/")
def hello():
  return "Hello there!"


# Bind the Events API route to your existing Quart app by passing the server
# instance as the last param, or with `server=app`.
slack_event_handler = AsyncSlackEventAdapter(SLACK_SIGNING_SECRET, "/slack/events", app)


# Create an event listener for "reaction_added" events and print the emoji name
@slack_event_handler.on("reaction_added")
def reaction_added(event_data):
  emoji = event_data["event"]["reaction"]
  print(emoji)


# Start the server on port 3000
if __name__ == "__main__":
  app.run(port=3000)
