# Is echarts ESM-only? Can you require() it?

> echarts@6.1.0 ships CommonJS and ESM builds. Dual package — require() works on every Node.js version we test; import works too.

Apache ECharts is a powerful, interactive charting and data visualization library for browser

Latest version 6.1.0, published May 19, 2026.

echarts publishes both a CommonJS entry and a native ESM entry (ESM added in 5.5.0). require("echarts") should work on every Node.js version the package supports; the runtime probe has not run for this version. import "echarts" works alongside it.

## What to do

1. Nothing to change. require("echarts") should work on every Node.js version the package supports; the runtime probe has not run for this version. import * as echarts from "echarts" works alongside it; use named imports for what the ESM entry exports.
2. TypeScript: types are bundled; install nothing extra.
