blockkit 1.8.1

A fast way to build Block Kit interfaces in Python.

---

Blockkit is a Python library for building UI interfaces for Slack apps. It allows you to compose the interface from Python classes, so you type less, and your code becomes more maintainable.

Blockkit performs validation at runtime and provides user-friendly errors when data is invalid.

Generate

You don't even need to write code yourself. Go to https://blockkit.botsignals.co paste your JSON payload from Block Kit Builder and get corresponding Python code!

Installation

pip install blockkit

Usage

Start with one of the Home, Modal, or Message surface classes and follow the structure as you would follow it in JSON.

The library supports all types of surfaces, blocks, block elements, and composition objects Slack provides.

Once UI is ready, call the build() method to render components to dictionary:

from blockkit import Section, MarkdownText

Section(text=MarkdownText(text="hello world")).build()

{"type": "section", "text": {"text": "hello world", "type": "mrkdwn"}}
