Webtask Slackin

Webtask Slackin is a Serverless implementation of Guillermo Rauch's Slackin for Webtask.io. It is specifically intended to address cold start issues that smaller groups have when hosting on free tier cloud providers like Heroku & Azure. If you have ever setup Slackin for your group and encountered broken badge images becuase of response timeouts, then Webtask Slackin is for you.

Features

• A landing page you can point users to to fill in their emails and recieve an invite (https://{your wt container}.run.webtask.io/webtask-slackin).
• A SVG badge that works well for static mediums (like GitHub README Pages).
• Super simple deployment to Webtask.io.

Usage

To deploy the webtask from the command line, follow these steps:

Note: These steps assume you have the Wetask CLI installed and initialized.

1. Clone the repository git clone https://github.com/NotMyself/webtask-slackin.git
2. Update the .meta file to include your Slack team name
3. Copy the .env_example file to a .env file
4. Update the .env file to include your Slack API token
5. Run the script scripts/publish

The output will look like this:

Note: The URL at the end of the output is where your webtask is hosted.

Tips

Your team id is what you use to access your login page on Slack (eg: https://{this}.slack.com).

You can find or generate your API test token at api.slack.com/web – note that the user you use to generate the token must be an admin. You need to create a dedicated @slackin-inviter user (or similar), mark that user an admin, and use a test token from that dedicated admin user. Note that test tokens have actual permissions so you do not need to create an OAuth 2 app. Also check out the Slack docs on generating a test token.
