In React Flow, edge types define how components interact, shaping the flow’s structure and user experience. Mastering these edge variations unlocks powerful ways to build dynamic, responsive workflows that respond seamlessly to user interactions.
Source and Target Edges: The Core Connection
Source edges initiate interactions from one component to another, while target edges receive and define where actions take effect. This fundamental pairing establishes directional flow and governs event propagation across nodes, forming the backbone of component communication.
Connection Edges: Bridging Global Workflows
Connection edges extend beyond individual nodes, linking separate flows or entire diagrams. They enable modular design and integration with external systems, making them ideal for complex applications that require cohesive multi-diagram navigation and data synchronization.
Custom Edge Variants: Tailoring Interaction Semantics
React Flow supports custom edge types to reflect unique business logic or user behavior. By implementing custom edge styles, labels, and behaviors, developers can create intuitive visual cues that enhance usability and clarify workflow intent.
Understanding and leveraging edge types in React Flow empowers developers to craft sophisticated, responsive diagrams that align with real-world interactions. By thoughtfully applying source, target, connection, and custom edge patterns, teams can build intuitive, maintainable workflows that elevate both design and functionality—start refining your React Flow projects today.
You can choose different kinds of edge types in React Flow: default (bezier), straight, step and smoothstep. React Flow provides several built. What Are Nodes and Edges? In React Flow, a diagram (or "flow") consists of two primary elements: Nodes: Visual elements positioned on the canvas that can represent any concept Edges: Connections between nodes that represent relationships These elements form the basis of any flow diagram, from simple charts to complex interactive applications.
It's also possible to create a custom edge, if you need special edge routing or controls at the edge. In this example we are demonstrating how to implement an edge with a button, a bi-directional edge, a self connecting edge. In all examples we are using the BaseEdge component as a helper.
React Flow comes with built-in edge types like "smoothstep" or "step". If you are using a custom edge component, it depends on your implementation how the edge path looks like. As you can see, React Flow comes with different edge types - bezier, step and smoothstep.
It's also possible to create a custom edge. The key to successful edge routing lies in finding the right balance between visual clarity and computational efficiency. Whether using built-in algorithms or implementing custom solutions, understanding these fundamental concepts enables the creation of sophisticated and responsive node.
The EdgeTypes type is used to define custom edge types. Hey everyone, in this video I will show you how to master custom edge in React Flow. We will cover these topics1) Understanding the basics of Custom Edges2).
React Flow Smart Edge Custom Edges for React Flow that never intersect with other nodes, using pathfinding.
