Quick facts
npm install vueThis package powers Vue.js
The vue package is the canonical implementation of Vue.js. Sourcemap Explorer uses this exact npm package as the framework-level fingerprint when it flags Vue.js on a page — both via the bundled node_modules/vue/ source paths and via the embedded package.json inside the JavaScript sourcemap.
Common pairings
Packages this one expects to find in the same project. Each is also a Sourcemap Explorer detection target.
How Sourcemap Explorer detects vue
We catch vue from two complementary signals: bundled source paths and the embedded package.json. Modern bundlers (webpack, Vite, esbuild, Rollup, Turbopack) preserve the original node_modules/vue/ 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
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.
- 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/vue/` — every match confirms the package is bundled. The matching `sourcesContent[i]` for `node_modules/vue/package.json` gives you the exact installed version.
- 3
Read the version directly from package.json
Run `jq -r '. as $m | $m.sources | to_entries[] | select(.value | endswith("node_modules/vue/package.json")) | $m.sourcesContent[.key] | fromjson | .version' bundle.js.map`. Sourcemap Explorer automates the same query in the popup.

FAQ
What is vue used for?
The progressive JavaScript framework for building modern web UI.
How can I tell if a website is using vue?
Open the page in Chrome with the Sourcemap Explorer extension installed and read the Stack tab. We catch `vue` from two complementary signals: `node_modules/vue/` paths inside the JavaScript sourcemap, and the embedded `package.json` we read for exact-version detection. Without the extension you can do the same lookup manually in DevTools — the steps are listed in the "How Sourcemap Explorer detects" section above.
What is the latest version of vue?
3.5.34, as published on the npm registry. The "Recent versions" table on this page lists the most recent 8 releases with their release dates. Sourcemap Explorer reports the version actually bundled into a site, which can lag the latest release by months on real-world deployments.
What is the relationship between vue and Vue.js?
vue is the canonical npm package for Vue.js. Sourcemap Explorer treats finding `vue` in a bundle as the framework-level signal that Vue.js is on the page, and the page you're reading is the canonical Sourcemap Explorer entry for the package itself.

Detected by Sourcemap Explorer
When a bundle ships sourcemaps, we read the embedded package.json for vue and report the precise version. Without sourcemaps, an import / require in the page's scripts is enough to flag it.
