Barfi is a Flow-Based Programming framework that offers a graphical programming interface. It is designed to integrate seamlessly into your existing Python applications.
Barfi serves as an abstraction of Graphical Programming, Flow-Based Programming, or Node Programming, where a Block corresponds to a Node, and a Link (or connection) corresponds to an Edge. These concepts go by different names, each reflecting specific needs or philosophies. In Barfi, they form the foundation of a framework for building, saving, and executing workflows as needed. The framework is intentionally kept simple, providing APIs that allow customization for diverse use cases and philosophies.
Many existing visual Flow-Based Programming (FBP) libraries/frameworks operate within their own confined isolated environments, limiting their usability as components in existing applications or scripts. Barfi addresses this by decoupling the graphical programming interface from the computation environment, which eables easy integration into existing apps. The graphical interface is provided through a Streamlit widget: st_flow (with a Jupyter Notebook widget currently in development), while the computation environment is managed independently via the ComputeEngine.
Quickstart
A workflow consists of a bunch of Blocks connected to each other, the information of the blocks and connections is stored in a FlowSchema, which is then executed to execute each program/function connected to each Block and to propagate the data from one Block to another.
Under the hood
The Flow Editor UI is built using ReactFlow.
