This package is used in [Browserslist](https://github.com/ai/browserslist), so you can use e.g. `electron >= 1.4` in [Autoprefixer](https://github.com/postcss/autoprefixer), [Stylelint](https://github.com/stylelint/stylelint), [babel-preset-env](https://github.com/babel/babel-preset-env) and [eslint-plugin-compat](https://github.com/amilajack/eslint-plugin-compat). **Supported by:** ## Install Install using `npm install electron-to-chromium`. ## Usage To include Electron-to-Chromium, require it: ```js var e2c = require('electron-to-chromium'); ``` ### Properties The Electron-to-Chromium object has 4 properties to use: #### `versions` An object of key-value pairs with a _major_ Electron version as the key, and the corresponding major Chromium version as the value. ```js var versions = e2c.versions; console.log(versions['1.4']); // returns "53" ``` #### `fullVersions` An object of key-value pairs with a Electron version as the key, and the corresponding full Chromium version as the value. ```js var versions = e2c.fullVersions; console.log(versions['1.4.11']); // returns "53.0.2785.143" ``` #### `chromiumVersions` An object of key-value pairs with a _major_ Chromium version as the key, and the corresponding major Electron version as the value. ```js var versions = e2c.chromiumVersions; console.log(versions['54']); // returns "1.4" ``` #### `fullChromiumVersions` An object of key-value pairs with a Chromium version as the key, and an array of the corresponding major Electron versions as the value. ```js var versions = e2c.fullChromiumVersions; console.log(versions['54.0.2840.101']); // returns ["1.5.1", "1.5.0"] ``` ### Functions #### `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: ```js 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. ```js 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`. ```js var chromeVersion = e2c.electronToChromium('9000'); // chromeVersion is undefined ``` #### `chromiumToElectron(query)` Arguments: * Query: string or number, required. A major or full Chromium version. Returns a string with the corresponding Electron version for a given Chromium query. If you provide it with a major Chromium version, it will return a major Electron version: ```js var electronVersion = e2c.chromiumToElectron('54'); // electronVersion is "1.4" ``` If you provide it with a full Chrome version, it will return an array of full Electron versions. ```js var electronVersions = e2c.chromiumToElectron('56.0.2924.87'); // electronVersions is ["1.6.3", "1.6.2", "1.6.1", "1.6.0"] ``` If a query does not match an Electron version, it will return `undefined`. ```js var electronVersion = e2c.chromiumToElectron('10'); // electronVersion 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 [Browserslist](https://github.com/ai/browserslist) 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: ```js var query = e2c.electronToBrowserList('1.4'); // query is "Chrome >= 53" ``` If a query does not match a Chromium version, it will return `undefined`. ```js var query = e2c.electronToBrowserList('9000'); // query is undefined ``` ### Importing just versions, fullVersions, chromiumVersions and fullChromiumVersions All lists can be imported on their own, if file size is a concern. #### `versions` ```js var versions = require('electron-to-chromium/versions'); ``` #### `fullVersions` ```js var fullVersions = require('electron-to-chromium/full-versions'); ``` #### `chromiumVersions` ```js var chromiumVersions = require('electron-to-chromium/chromium-versions'); ``` #### `fullChromiumVersions` ```js var fullChromiumVersions = require('electron-to-chromium/full-chromium-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. To verify correct behaviour, run `npm test`. ## License [![FOSSA Status](https://app.fossa.io/api/projects/git%2Bgithub.com%2FKilian%2Felectron-to-chromium.svg?type=large)](https://app.fossa.io/projects/git%2Bgithub.com%2FKilian%2Felectron-to-chromium?ref=badge_large)
