Two years ago, we wrote about building a Slack bot to automatically tweet new JDriven blog posts, and inform us about this using our dedicated internal Slack channel. Life was simple then. If it was on Twitter, it was "online".

But the social media landscape has fragmented and augmented. The tech community has spread, at least across X, Mastodon, and Bluesky. So to reach our audience today, we have to tweet, toot and who knows what to reach them.

We needed to upgrade our trusty Slack bot from a single-channel poster to an omnichannel syndication engine. In this post, I’ll walk you through how I refactored our Deno-based Slack app to handle multiple platforms, manage distinct authentication protocols, and ensure we don’t spam our followers with duplicate posts.

To check if a string value starts or ends with a given string you can use the str starts-with and str ends-with commands. The command returns a boolean value: true if the string starts or ends with the given string and false otherwise. The commands are case sensitive by default. You can use the --ignore-case (or the shorthand -i) to ignore casing while checking if a the string starts or ends with a given string.
To input can be a string value and then that string value is checked. If the input is an array of string values, then each element is checked. It is also possible to check values in a record or table. You need to pass the names of the field(s) or column(s) that you want to check the string values of.
