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.
- 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.
To deploy the webtask from the command line, follow these steps:
Note: These steps assume you have the Wetask CLI installed and initialized.
- Clone the repository
git clone https://github.com/NotMyself/webtask-slackin.git - Update the
.metafile to include your Slack team name - Copy the
.env_examplefile to a.envfile - Update the
.envfile to include your Slack API token - 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.
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.
