## What it is
Flume is a React-powered node editor library that lets developers build user-friendly visual editors for modeling business logic as JSON graphs. It includes a runtime engine (RootEngine) to execute those graphs in any JavaScript environment, with type-safe ports preventing invalid connections.

## Use cases
- let end-users customize business logic with a visual node editor
- extract business logic from app code into portable JSON graphs
- build a visual programming language with type-safe connections
- render a node editor in a React app
- execute user-defined logic graphs at runtime
- create workflow or rule builders for non-developers

## When to choose
- you need a polished, type-safe node editor embedded in a React application
- you want users to define and edit logic visually that your app can execute
- you need logic graphs portable across JavaScript environments

## When to avoid
- you need a general-purpose diagramming or flowchart tool rather than executable logic graphs
- your project does not use React and you cannot adopt it
- you need a full data-pipeline or ETL visual builder out of the box
