b9ui 0.2.0

The Next.js like Python framework

b9ui is a lightweight framework for building HTML pages with a component approach similar to Next.js. It is designed so that developers need to write almost no JavaScript to create dynamic web services.

[!]

The framework is in a very early development/testing phase. There are currently a lot of half-functioning features. We welcome your contributions to help progress!

Requirements

python = "^3.12" ludic = "^0.4.0"

Installation

pip install “b9ui”

Similar to Starlette, you will also want to set up an ASGI server:

pip install uvicorn
