About React Flow
What is React Flow?
React Flow is a powerful, open-source React library that lets you build interactive node-based UIs, such as workflow editors, network graphs, and drag-and-drop diagramming tools. It handles rendering, interactions, and layout so you can focus on the application logic.
Who is it for?
React Flow is ideal for developers building data pipelines, whiteboard apps, automation tools, or any interface that requires connecting nodes with edges. It is not for non-technical users or those seeking a no-code drag-and-drop builder without React expertise.
Key Use Cases
Common applications include mind map apps, audio visualization tools, server-side rendering flows, multiplayer whiteboards, and custom control panels. The library offers extensive customization: custom nodes, edges, handles, and theming out of the box.
Key features
- Customizable Nodes — Build any node shape with React components, add handles, resizers, and toolbars.
- Flexible Edges — Supports bezier, straight, smooth-step, and custom edge types with labels and markers.
- Interactive Viewport — Pan, zoom, and drag nodes with smooth animations and minimap support.
- Built-in Hooks & Providers — Use hooks like useNodes, useEdges, and useReactFlow for state management and seamless integration.
- Layouting & Sub Flows — Auto-layout nodes, nest sub-flows, and manage complex hierarchies.
- Accessibility & Testing — A11y-friendly and built with TypeScript for robust development.
