A quick-and-dirty out-of-office Slack autoreply based on NodeJS.

Sends an ephemeral message when someone DMs you. Use chat.postMessage if you want to send an actual message.

You'll need NodeJS (tested on 12.15.0) and the Slack legacy token.

yarn install

Clone the .env.example file to .env

cp .env.example .env

Request your Slack legacy token and replace xoxp-your-token in the .env file with it.

yarn start

Install pm2

npm install pm2@latest -g

Start the server by running

pm2 start server.js --name your-app-name

Alternatively, for convenience you can create a ecosystem.config.js config file with the following example and simply run pm2 start

module.exports = {
  apps: [
    {
      name: "your-app-name",
      script: "server.js"
    }
  ]
};

The server.js uses the "Require hook" hack, check it out here.

Enjoy!
