ductile-ui 0.2.6

A library provides interactive ui for discord.py

ductile-ui

A library provides declarative UI for discord.py.

Features

• Declarative UI, inspired by React.
• Component-oriented with State
• Fully typed

Installation

Python3.10 or higher is required

discord.py^2.2.0 is required; any compatibility under 2.1.x or 1.x is not guaranteed

Using the latest stable release of discord.py is recommended

  pip install ductile-ui

Usage/Examples

You can define component as return value of View.render(). To store state, use State.

# This example requires the 'message_content' privileged intent to function.
