Slack Q&A

An easy plug-and-use library for developing Slack BOT that serves a Q&A-like use case.

For Python version, please see https://github.com/lokwkin/slack-qna-python

Description

High level flow:

1. User messages this BOT via either:
   1. Direct Message
   2. Mention in Channel
   3. Slack Command
2. The BOT shows a loading reaction to the message.
3. The BOT relays user's message to your custom handler, and expect for a result either in Text, File or Image type.
4. The BOT reply the user's message in Slack Thread.
5. The BOT also shows a success reaction to the message.

Note:

• This BOT uses Slack's Socket Mode instead of Webhook mode for slack connection, so it does not require an exposed public endpoint. But your services need to be long running.

Usage

Install

npm install --save slack-qna-node

import { SlackQna, IncomingMessage } from 'slack-qna-node';

const slackQnABot = new SlackQna({_
    slackBotToken: '<SLACK_BOT_TOKEN>',
    slackAppToken: '<SLACK_APP_TOKEN>',
    botUserId: '<SLACK_BOT_USER_ID>'
});

slackQnABot.registerHandler({
  isSync: true,         // If isSync = true, it would reply the user with the handler function result.
                        // If isSync = false, you would need to call slackQnABot.postMessage(OutgoingMessage) on your own.
  dataType: 'image',    // Expected output. Can either be "text", "file" or "image"
  handler: async (message: IncomingMessage) => {
    // Your logic goes here.
    return 'Hi there';
  },
});

slackAdapter.listen({
  directMessage: true,
  mention: true,
  command: true
});
