Getting started — installation and minimal setup

Installation is intentionally boring: you npm-install the wrapper and the underlying Sigma runtime. If you want the short paste-ready command for a terminal — here it is.

npm install react-sigmajs sigma --save
# or
yarn add react-sigmajs sigma

After install, import the React component wrapper and feed it a graph object (nodes + edges). The wrapper expects a Sigma-compatible data shape: nodes with id/x/y/size/color and edges with id/source/target/size/color. Keep geometry simple — Sigma handles rendering.

Minimal example (conceptual): import the component, define graph JSON, render. This is the canonical snippet that gets copied into tutorials and answers the “how do I start” intent — perfect for featured snippets and voice queries.

import React from 'react';
import Sigma from 'react-sigmajs';

const graph = {
  nodes: [
    { id: 'n1', label: 'Node 1', x: 0, y: 0, size: 8, color: '#f00' },
    { id: 'n2', label: 'Node 2', x: 1, y: 1, size: 8, color: '#0f0' }
  ],
  edges: [
    { id: 'e1', source: 'n1', target: 'n2', size: 2 }
  ]
};

export default function App() {
  return ;
}

Note: real projects usually compute x/y using a layout (force-directed) or import coordinates from back-end processing. If you prefer runtime layout, use Sigma’s layout plugins or compute positions before mounting the React component.

Building an interactive example — events and state

Interactivity is the value proposition: pan/zoom, hover tooltips, node selection, and custom click behaviors. React Sigma.js exposes event hooks; bind them to update your React state or trigger side-effects (analytics, side panels).

Typical pattern: attach event listeners in a ref or via props, and map Sigma events to React handlers. Keep heavy computations out of render paths — updating huge graph objects in state can be expensive. Instead mutate Sigma’s graph instance or keep a lightweight ID-based React state.

Example idea: on node click, highlight neighbors and populate a detail sidebar. Use a small state object like {selectedId: ‘n1′} and rely on Sigma’s renderer to change node colors via attributes or custom renderers.

Customization, plugins and rendering tips

You can customize node/edge appearance, add labels, and create custom renderers with Sigma plugins. Plugins typically handle layouts (forceAtlas2), animations, or input controls. Check the plugin list in the Sigma.js ecosystem for ready-made features.

Common customization tasks:
– change node colors/sizes based on attributes,
– implement dynamic tooltips on hover,
– add edge curvature or directional arrows using renderers.

Two realistic ways to implement custom visuals: set attributes on nodes/edges (color/size/label) or inject a custom canvas/WebGL renderer if you need pixel-perfect control. The former is easier and sufficient for most dashboards.

Performance & best practices

Sigma.js uses WebGL which helps, but performance is still a function of graph size, layout compute, and DOM/React updates. Avoid re-creating the entire graph object on every render — mutate the existing Sigma instance or use shallow updates keyed by id.

Practical tips:

• Precompute layouts server-side when possible; transfer x/y positions instead of computing in-browser.
• Batch updates: add/remove nodes/edges in groups, not one-by-one per render.
• Use level-of-detail: simplify visuals when zoomed out (smaller labels or hidden labels).

For extremely large graphs (>10k nodes), consider simplified visualization (sampling, clustering) or alternative libraries specialized for massive datasets. Always profile — expensive CPU work often comes from layout algorithms, not rendering.

FAQ (short, to-the-point answers)

How do I install and set up react-sigmajs?

Install via npm or yarn (npm i react-sigmajs sigma). Import the Sigma React component, provide a graph object (nodes/edges), and render. Use layout plugins or precomputed coordinates for positioning.

Can I customize node styles and interactions in react-sigmajs?

Yes. Set node/edge attributes (color, size, label), attach event handlers for hover/click, and use Sigma plugins or custom renderers for advanced visuals like arrows or curved edges.

Is react-sigmajs suitable for large graphs and real-time updates?

Sigma uses WebGL and performs well for medium-to-large graphs. For very large graphs, apply sampling/clustering, server-side layout, and batch updates to keep UI responsive. For real-time updates, mutate the Sigma instance or send incremental diffs instead of replacing whole objects.
