react.joint v1.0.2

React JointJS

React wrapper for JointJS: refer to their documentation to learn how to customize JointJS.

React JointJS aims at simplifying the integration with React by letting you render nodes and ports with React components.

Install

yarn add react.joint

Usage

API:

type Port = joint.dia.Element.Port & {
  element: JSX.Element;
  id: string;
  size: { width: number; height: number };
};

type Node = joint.dia.Element.Attributes & {
  element: JSX.Element;
  type: string;
  id: string;
  size: { width: number; height: number };
  position: { x: number; y: number };
  ports: Array<Port>;
};

type Props = {
  graph: joint.dia.Graph;
  paperOptions: joint.dia.Paper.Options;
  nodes: Array<Node>;
  links: Array<joint.dia.Link>;
  paperRef: (paper: joint.dia.Paper) => void;
};

<ReactJointJS

    id: node.id,

      x: node.x,
      y: node.y
    },
    size: {
      width: 100,

    element: <GraphNode id={node.id} />,
    type: "MyNode",

        element: <Port1 label="Out 1" />,

        },
        target: { id: link.target, port: `${link.target}_3` },

    width: graphSize.width + 200,

Under the hood

React JointJS uses foreignObject and portals to render your React components inside the svg created and managed by JointJS.
