Slack Status Updater

A Cloudflare Worker that automatically updates your Slack status based on your Google Calendar work location. The worker checks your calendar events daily and sets your Slack status to "Working remotely" when you're working from home.

Features

• Automatically checks Google Calendar events for work location
• Updates Slack status to "Working remotely" when working from home
• Sends notifications when work location is not set for scheduled events
• Runs daily at 8:00 AM via Cloudflare Cron
• Supports both office and home working locations
• Prevents duplicate status updates

Acknowledgments

This project was developed with the assistance of Cursor, and Large Language Models (LLMs). Their capabilities in code generation, debugging, and documentation were invaluable in creating this tool efficiently.

Prerequisites

• A Google Calendar API project with OAuth 2.0 credentials
• A Slack workspace with appropriate API tokens
• Node.js and npm installed
• Wrangler CLI installed (npm install -g wrangler)

Setup

1. Clone the repository:

git clone https://github.com/ulrikandersen/slack-status-updater.git
cd slack-status-updater

2. Install dependencies:

npm install

3. Set up environment variables:

   • Copy the example configuration file:

   cp .dev.vars.example .dev.vars

   • Edit .dev.vars with your actual credentials:
     • GOOGLE_CLIENT_ID: Your Google OAuth client ID
     • GOOGLE_CLIENT_SECRET: Your Google OAuth client secret
     • GOOGLE_REFRESH_TOKEN: Your Google OAuth refresh token (obtained via get_token.ts)
     • SLACK_USER_TOKEN: Your Slack user token (starts with xoxp-)
     • SLACK_BOT_TOKEN: Your Slack bot token (starts with xoxb-)
     • SLACK_USER_ID: Your Slack user ID

4. Get your Google OAuth refresh token:

   • Make sure your .dev.vars file has GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET set
   • Run the token generator:

   npx ts-node get_token.ts

   • Open the provided URL in your browser
   • Authorize the application
   • Copy the refresh token from the console output to your .dev.vars file

Local Development

1. Start the development server:

wrangler dev

2. Access the status endpoint:
   • Open your browser and navigate to http://localhost:8787/status
   • This will trigger the status check manually

Deployment

1. Login to Cloudflare:

wrangler login

2. Set up your secrets in the Cloudflare dashboard:

   • Go to https://dash.cloudflare.com
   • Navigate to Workers & Pages
   • Select your worker
   • Go to Settings > Variables
   • Add all the environment variables from your .dev.vars file

3. Deploy the worker:

wrangler deploy

Environment Variables

The following environment variables are required:

Variable	Description
GOOGLE_CLIENT_ID	Google OAuth client ID
GOOGLE_CLIENT_SECRET	Google OAuth client secret
GOOGLE_REFRESH_TOKEN	Google OAuth refresh token
SLACK_USER_TOKEN	Slack user token (starts with xoxp-) - used for setting status
SLACK_BOT_TOKEN	Slack bot token (starts with xoxb-) - used for sending reminder message
SLACK_USER_ID	Your Slack user ID

How It Works

1. The worker runs daily at 8:00 AM via Cloudflare Cron
2. It checks your Google Calendar events for the current day
3. If you have events scheduled:
   • If your work location is set to "Home", it updates your Slack status to "Working remotely"
   • If no work location is set, it sends you a Slack message to set your location
4. The status is only updated if you don't already have a status set
