A Python Toolkit for Modern Web-Based User Interfaces

Flexx: A Python Toolkit for Modern Web-Based User Interfaces

Flexx is a powerful Python toolkit designed to create graphical user interfaces (GUIs) using web technology. This innovative framework allows developers to write applications purely in Python while automatically generating the necessary JavaScript through the PScript transpiler. Whether you’re building cross-platform desktop applications, web apps, or stand-alone HTML documents, Flexx provides a flexible and efficient solution.

The motivation behind Flexx is the growing popularity of web-based applications, including interactive scientific content. With Flexx, developers can leverage the browser technology that users are already familiar with, resulting in a smaller and more accessible library that is easy to use.

While Flexx offers great versatility, it’s important to keep in mind that different usage scenarios require careful separation of Python and PScript code. This ensures maintainability and prevents potential issues down the line. As a developer, it’s crucial to strike the right balance and make informed decisions when mixing server-side Python and browser-side Python.

To get started with Flexx, make sure you have Python 3.5+ installed (including pypy). Additionally, Flexx relies on several libraries, including Tornado, PScript, Webruntime, and Dialite. Installing the latest release can be done using the following command:
pip install flexx
For those who want to stay on the cutting edge, the latest version from GitHub can be installed with:
pip install -U https://github.com/flexxui/flexx/archive/master.zip
Flexx is designed to support all modern browsers, such as Firefox, Chrome, and Edge. While Internet Explorer versions 10 and above should work, some features may not perform optimally. If you plan on running desktop apps, ensure that you have either Firefox or NW.js installed.

Flexx is licensed under the liberal 2-clause BSD license, providing developers with the freedom to use the toolkit in their projects. Additional licensing details can be found in the LICENSE file.

By choosing Flexx as your Python toolkit for web-based user interfaces, you can unlock the potential of browser technology to create dynamic and responsive applications. Explore the documentation, examples, and community support to make the most of this innovative framework. Embrace the power of Python and web technology with Flexx!
