Core Engine

Package:

npm install @casewavejs/core

@casewavejs/core is the headless graph engine. It does not depend on React.

Create Graph

import { CaseWaveGraph } from "@casewavejs/core";

const graph = new CaseWaveGraph({
  allowCycles: true,
  allowDanglingEdges: false,
  hypergraphMode: true,
  readonly: false
});

Add Node

graph.addNode({
  id: "node_1",
  type: "person",
  position: { x: 100, y: 120 },
  size: { width: 180, height: 90 },
  data: {
    name: "Person A"
  }
});

Update Node

graph.updateNode("node_1", {
  position: { x: 240, y: 160 },
  locked: true
});

Add Edge

graph.addEdge({
  id: "edge_1",
  type: "default",
  source: { kind: "node", nodeId: "node_1" },
  target: { kind: "node", nodeId: "node_2" },
  direction: "directed",
  relation: "related",
  routing: "bezier"
});

Snapshot

const snapshot = graph.snapshot({
  reason: "before user action"
});

Undo / Redo

graph.undo();
graph.redo();

Export JSON

const schema = graph.toJSON();

Load JSON

graph.load(schema);

Validate

const result = graph.validate();

if (!result.valid) {
  console.log(result.errors);
}
