The Short Answer

Use Recharts if you want a React-native declarative API and good TypeScript support. Use Chart.js (via react-chartjs-2) if you need maximum performance with large datasets or already know Chart.js from a non-React project.

API Design

This is where the two libraries differ most fundamentally. Recharts is component-based — you compose charts by nesting React components:

// Recharts — declarative, React-native
<BarChart data={data}>
  <XAxis dataKey="name" />
  <Bar dataKey="value" fill="#00e5a0" />
</BarChart>

Chart.js uses a configuration object, more similar to traditional charting libraries:

// Chart.js — config object style
const config = {
  type: 'bar',
  data: { labels, datasets: [{ data, backgroundColor: '#00e5a0' }] },
  options: { responsive: true }
};
<Bar data={config.data} options={config.options} />

Bundle Size

Chart.js wins on bundle size. Its canvas-based rendering is more efficient and tree-shakeable:

Library	Minified	Gzipped
Recharts	~480KB	~130KB
Chart.js + react-chartjs-2	~240KB	~72KB

Performance

Chart.js renders on a <canvas> element, which is significantly faster for large datasets (5,000+ data points). Recharts renders SVG, which is more flexible for custom styling but slower at scale.

For most dashboards with under 1,000 data points, the performance difference is imperceptible. Only optimize for Chart.js if you're building real-time monitoring tools or financial tick data charts.

TypeScript Support

Both libraries have good TypeScript support in 2025. Recharts ships its own types. Chart.js requires @types/chart.js which is well-maintained.

Recharts has the edge here because its component-based API makes prop types more intuitive — you get autocomplete on component props rather than deeply nested config objects.

Customization

Recharts is more customizable for React developers. You can pass custom React components as tooltips, labels, and legends. Chart.js customization requires writing plugin callbacks.

When to Use Each

Choose Recharts when: building React/Next.js dashboards, need custom React components in tooltips, want declarative code, TypeScript-first project
Choose Chart.js when: rendering 5,000+ data points, migrating from a non-React codebase, need canvas export (to PNG/PDF), minimal bundle size is critical
