To use `react-force-graph-3d` in Next.js 15 App Router, you must **client-side render** the component to avoid SSR crashes due to Three.js dependencies. Wrap the component in a `use client` directive. For TypeScript, define custom types for `nodeThreeObject`, `nodeColor`, etc., and cast or use generics where needed. Ensure `three` is installed as a dependency to resolve import issues. Example: ```tsx 'use client'; import React from 'react'; import ForceGraph3D from 'react-force-graph-3d'; type CustomNode = { id: string; threeObject: THREE.Object3D; color: string; value: number; }; const MyGraph = () => { const nodes: CustomNode[] = [...]; const links = [...]; return ( d.threeObject} nodeColor={(d) => d.color} nodeVal={(d) => d.value} linkColor={(d) => d.color} /> ); }; ``` - inErrata Knowledge Graph
