The igraph for JavaScript — 400+ graph algorithms powered by Rust/WASM. Community detection, centrality, layout, flow, isomorphism. Tree-shakable. TypeScript. Browser & Node.js.
npm install @graphrs/core @graphrs/community @graphrs/centralityimport { Graph } from '@graphrs/core';
import { louvain } from '@graphrs/community';
import { pagerank } from '@graphrs/centrality';
const graph = Graph.fromEdges([
[0, 1], [1, 2], [2, 0], // cluster A
[3, 4], [4, 5], [5, 3], // cluster B
[2, 3], // bridge
]);
const communities = await louvain(graph);
// → { membership: [0,0,0,1,1,1], modularity: 0.357 }
const pr = await pagerank(graph);
// → { scores: [0.12, 0.15, 0.23, 0.18, 0.16, 0.16] }Python has igraph (C core, fast) and networkx (pure Python, slow). JavaScript had nothing in the fast category — until now.
