electron-to-chromium

What is electron-to-chromium?

The electron-to-chromium package provides a mapping between Electron versions and Chromium versions. It allows developers to determine which version of Chromium is used in a given version of Electron. This is particularly useful for web developers targeting Electron applications, as it helps in understanding browser compatibility and feature support.

What are electron-to-chromium's main functionalities?

Get Chromium version for a specific Electron version

This feature allows you to get the Chromium version that corresponds to a specific Electron version.

"const electronToChromium = require('electron-to-chromium');
const chromiumVersion = electronToChromium.electronToChromium('9.0.0');
console.log(chromiumVersion); // Outputs the Chromium version used in Electron 9.0.0"

Get Electron versions for a specific Chromium version

This feature allows you to get all Electron versions that use a specific Chromium version.

"const electronToChromium = require('electron-to-chromium');
const electronVersions = electronToChromium.chromiumToElectron('83.0.4103.122');
console.log(electronVersions); // Outputs an array of Electron versions using Chromium 83.0.4103.122"

Get full list of Electron-to-Chromium mappings

This feature provides the full list of mappings between Electron and Chromium versions.

"const electronToChromium = require('electron-to-chromium');
const fullList = electronToChromium.fullList;
console.log(fullList); // Outputs the complete list of mappings"

Other packages similar to electron-to-chromium

browserslist

The browserslist package allows you to share target browsers and Node.js versions between different front-end tools. It is similar to electron-to-chromium in that it helps developers target specific browser versions, but it is more general and not limited to Electron's Chromium versions.

caniuse-lite

caniuse-lite is a lighter version of the caniuse database, providing browser support tables for front-end technologies. While it does not directly map Electron versions to Chromium, it serves a similar purpose in informing developers about feature support and compatibility across different browsers and versions.

electron-releases

electron-releases is a package that provides information about Electron releases, including version numbers, release dates, and more. It is similar to electron-to-chromium in that it provides data about Electron versions, but it does not focus on the mapping to Chromium versions.

README

Electron-to-Chromium

This repository provides a mapping of Electron versions to the Chromium version that it uses.

This package is used in Browserslist, so you can use e.g. electron >= 1.4 in Autoprefixer, Stylelint, babel-present-env and eslint-plugin-compat.

Install

Install using npm install electron-to-chromium.

Usage

to include electron-to-chromium, require it:

var e2c = require('electron-to-chromium');

Properties

The Electron-to-Chromium object has 4 properties to use:

versions

An object with all major Electron versions as keys and their respective major Chromium version as string value.

var versions = e2c.versions;
console.log(versions['1.4']);
// returns "53"

fullVersions

An object with all Electron versions as keys and their respective Chromium version as value.

var versions = e2c.fullVersions;
console.log(versions['1.4.11']);
// returns "53.0.2785.143"

electronToChromium(query)

Arguments:

• Query: string or number, required. A major or full electron version.

A function that returns the corresponding Chromium version for a given Electron function. Returns a string.

If you provide it with a major Electron version, it will return a major Chromium version:

var chromeVersion = e2c.electronToChromium('1.4');
// chromeVersion is "53"

If you provide it with a full Electron version, it will return the full Chromium version.

var chromeVersion = e2c.electronToChromium('1.4.11');
// chromeVersion is "53.0.2785.143"

If a query does not match a Chromium version, it will return undefined.

var chromeVersion = e2c.electronToChromium('9000');
// chromeVersion is undefined

electronToBrowserList(query) DEPRECATED

Arguments:

• Query: string or number, required. A major Electron version.

Deprecated: Browserlist already includes electron-to-chromium.

A function that returns a Browserlist query that matches the given major Electron version. Returns a string.

If you provide it with a major Electron version, it will return a Browserlist query string that matches the chromium capabilities:

var query = e2c.electronToBrowserList('1.4');
// query is "Chrome >= 53"

If a query does not match a Chromium version, it will return undefined.

var query = e2c.electronToBrowserList('9000');
// query is undefined

importing just versions or fullVersions

Both the versions and the fullVersions list can be imported on their own, if file-size is a concern.

versions

var versions = require('electron-to-chromium/versions');

fullVersions

var fullVersions = require('electron-to-chromium/full-versions');

Updating

This package will be updated with each new Electron release.

To update the list, run npm run build.js. Requires internet access as it downloads from the canonical list of Electron versions.
