About

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

What detecting echarts tells you about a site

echarts (Apache ECharts) is a heavyweight, canvas-first charting engine with a vast feature set: large datasets, geographic maps, candlesticks, dense interactive dashboards. Spotting it signals a data-serious application where visualisation is a core feature, not decoration, and frequently points to enterprise, fintech, monitoring or analytics products. It is also extremely common on Chinese-origin and large-scale platforms given its origins at Baidu and adoption in that ecosystem, so its presence can hint at the project's lineage as much as its capabilities.

Why the exact echarts version matters

ECharts 5 was a major release that reworked the API surface, introduced tree-shakeable modular imports and changed defaults versus the version 4 line. The exact version therefore tells you whether the build can selectively import components (a big bundle-size difference) or pulls the full monolith, and which generation of chart types and options the configuration was written against.

echarts in a real-world stack

When you find echarts in a bundle, it rarely travels alone. Sometimes echarts-for-react on React projects; otherwise used framework-agnostically.

Quick facts

What echarts pulls in

echarts declares 2 direct dependencies — each one also rides into any bundle that ships echarts, so they are detection targets too. Reading them is a quick way to understand the package's real footprint .

How Sourcemap Explorer detects echarts

echarts ships as v6.1.0, published 2026-05-19 and carries 2 direct dependencies, 117 versions on the registry. Those exact numbers are the footprint Sourcemap Explorer matches when echarts rides inside a deployed bundle — here is how the detection works.

We catch echarts from two complementary signals: bundled source paths and the embedded package.json. Modern bundlers (webpack, Vite, esbuild, Rollup, Turbopack) preserve the original node_modules/echarts/ paths inside the JavaScript sourcemap's sources[] array — that's the canonical signal. When the matching package.json is also captured in sourcesContent[], we read the exact version field — patch number included. No regex guessing, no version inference.

1. 1

   Confirm the site exposes sourcemaps

   In DevTools Network, check the response headers of any application script for `SourceMap` or `X-SourceMap`. Failing that, fetch the script's last 4 KB and look for a `//# sourceMappingURL=` comment — that map is where the `echarts` paths live.

2. 2

   Find the package in the bundle

   Open DevTools → Network → reload. Click any application script and look at its sourcemap. Inside, search `sources[]` for entries matching `node_modules/echarts/` — every match confirms the package is bundled. The matching `sourcesContent[i]` for `node_modules/echarts/package.json` gives you the exact installed version.

3. 3

   Read the version directly from package.json

   Run `jq -r '. as $m | $m.sources | to_entries[] | select(.value | endswith("node_modules/echarts/package.json")) | $m.sourcesContent[.key] | fromjson | .version' bundle.js.map`. Sourcemap Explorer automates the same query in the popup.

Major releases of echarts

When each major version first landed. Major bumps are where breaking changes live, so this timeline is the fastest way to date the echarts version a site actually ships against the ecosystem.

Recent security advisories for echarts

The 1 most recent advisories affecting some versions of echarts, aggregated from OSV.dev (GitHub Advisory + CVE data). A listing here doesn't mean the version a given site ships is affected — each advisory applies to a specific version range. Sourcemap Explorer reads the exact bundled version so you can check it against these ranges.

Build

Build echarts source code:

Execute the instructions in the root directory of the echarts: (Node.js is required)

# Install the dependencies from NPM:
npm install

# Rebuild source code immediately in watch mode when changing the source code.
# It opens the `./test` directory, and you may open `-cases.html` to get the list
# of all test cases.
# If you wish to create a test case, run `npm run mktest:help` to learn more.
npm run dev

# Check the correctness of TypeScript code.
npm run checktype

# If intending to build and get all types of the "production" files:
npm run release

Then the "production" files are generated in the dist directory.
