# Electron-to-Chromium [](https://www.npmjs.com/package/electron-to-chromium) [](https://travis-ci.org/Kilian/electron-to-chromium) [](https://www.npmjs.com/package/electron-to-chromium) [](https://codecov.io/gh/Kilian/electron-to-chromium)[](https://app.fossa.io/projects/git%2Bgithub.com%2FKilian%2Felectron-to-chromium?ref=badge_shield)

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

## 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`.
 |
