Raw Blame History

electron-fingerprints Zero Dependencies

Generates fingerprints for electron version detection by downloading electron releases and generating checksums (sha1 hashes) of the files contained in each release. Published as a lookup table on the GitHub NPM Registry.

why

You can use this to guess which electron version is being used in a given application. A given electron version is (almost always) tightly bound to a node and chrome release as well, so you get a better sense of what the application is running.

Written as the backend for which-electon.

install

See the GitHub documentation to configure the GitHub Packages NPM Registry.

Install from the command line:

npm install @captn3m0/electron-fingerprints@2022.3.31

Install via package.json:

"@captn3m0/electron-fingerprints": "2022.3.31"

usage

This is just the raw data files, see which-electron for a usable package. The lookup.json file is published as the electron-fingerprints package on NPM. Programmatic usage is still possible:

const lookup = require("electron-fingerprints");
// baf786083f482c1f035e50e105b5f7475af1e00b = sha1(ffmpeg.dll)
lookup["win32-x64"]["baf786083f482c1f035e50e105b5f7475af1e00b"];
// ["v1.4.3", "v1.4.4", "v1.4.5"]

You can sort or filter the returned versions if needed. If you'd like to access the raw data, see HACKING.md for a schema description.

supported releases

All Stable electron releases for the following architectures are fingerprinted:

  • linux-x64
  • linux-arm64
  • darwin-x64 (Mac OS)
  • win32-x64 (Windows)
  • win32-arm64 (Windows)
  • darwin-arm64 (Apple Silicon)

A list of release fingerprints is under the hashes directory. Releases made when Electron was still called atom-shell are not supported (Before April 2015).
