Azure Function that acts as a bot which creates notifications in a Slack channel about StackOverflow activity based on the question tags.

1. Create a new timer based Azure Function (for javascript). For instructions see the docs. I recommend a timer that will fire every 15 minutes, due to the api request limitations of Stack Overflow.
2. Install the required node.js packages. Instructions can be found here. The package.json file is in this repository.
3. Replace the default javascript code with the code in this repository. Then change the configuration to your liking*

• A Slack token can be generated here. A StackOverflow token can be created here.

The configuration is defined using environment variables:

    slackbot_username: "StackOverflow Tag Tracker",
    slackbot_icon_emoji: ':incoming_envelope:',
    slackbot_token: '<token>',
    slackbot_channel: '<channel>',
    slackbot_workspace: '<workspace>',
    so_api_key: '<api key>',
    so_tracked_tags: 'azure;asp.net-web-api|powerbi',
