A deep dive into Slack’s Block Kit

Watch the Video

Okay, so this video’s all about leveling up your Slack game with Block Kit and a Next.js app. We’re talking about ditching plain text messages and building rich, interactive experiences in Slack using JSON. The video walks through common message types, shows how to handle user interactions, and even provides a ready-to-go Next.js app you can clone and tweak.

Why’s this valuable for us as developers embracing the AI/no-code revolution? Well, think about it: Slack is where so much collaboration happens. Being able to automate and enhance those interactions with Block Kit and a bit of Next.js code opens up a *ton* of possibilities. Instead of manually triggering actions or sifting through notifications, you could build bots that automatically surface relevant information, collect user input, and even trigger workflows in other systems. Plus, Knock’s UI and API integrations can make this even easier to manage at scale.

I’m personally excited to give this a try. I’ve been looking for ways to streamline our internal communication and automate some of the repetitive tasks that clog up our workflow. Imagine being able to build a Slack bot that automatically kicks off a CI/CD pipeline when a team member approves a pull request, or one that surfaces relevant documentation based on the channel someone’s posting in. It could mean less context switching, faster turnaround times, and happier developers all around. Definitely worth an afternoon of experimentation.
