A nodejs Azure Function to post to Slack
- You will need an Azure subscription. You can get one for free here
- your brain
- Fork this project
- Create an
Azure function Appfrom the portal (as at this time Azure Functions are still in preview you may want to go here - Set the forked repo as your deployment source (gear icon)
- Create a function called
Slackbot(or whatever name you have changed the function into in your fork) - wait for the repo to sync
- Tricky part: for whatever reason Azure Functions do not run
npm install. Therefore you need to go toFunction app Settings - Kuduand open the console, go tosite/wwwroot/Slackbotand runnpm installfrom the console command-line - go to the
Function app settings - Create a Slack Webhook
- Add an
App SettingnamedSLACK_URLto your Azure Function, pointing to the Slack Webhook - Test the function by adding a payload (HTTP POST) to the functions's
