Shiny Express – Reactive web framework for data science in Python
Shiny is an open source web framework for data scientists to create interactive web applications, using Python or R. Shiny for R has been around since 2012, Shiny for Python since 2022. Today, we're releasing Shiny Express, a new syntax for writing Shiny for Python apps that is dramatically simpler and more concise. You can write full-stack interactive applications that manipulate and visualize your data in realtime, using a syntax that is highly reminiscent of writing a regular Python script.
In plain words
Shiny Express is an open source web framework that lets Python data scientists build interactive web applications with a simplified syntax resembling standard Python scripts. It enables real-time data manipulation and visualization in full-stack applications without requiring extensive web development knowledge. This new syntax for Shiny for Python offers a more concise alternative to previous versions, making it accessible to those primarily experienced with data science rather than web development.
