|
|
|
|
## ✨ Features
|
|
|
|
- Express
|
|
- TypeScript
|
|
- Slack webhook route
|
|
|
|
## 💁♀️ How to use
|
|
|
|
- Create a Slack app with an [incoming webhook](https://api.slack.com/messaging/webhooks).
|
|
- Click the deploy button and add the `SLACK_WEBHOOK_URL`.
|
|
- Install dependencies `yarn`
|
|
- Connect to your Railway project `railway link`
|
|
- Start the development server `railway run yarn dev`
|
|
|
|
## 📝 Notes
|
|
|
|
The server started simply returns `Hello from the webhook! :rocket:`. You can consume whatever information you'd like from your custom webhook, parse it and send it to Slack accordingly.
