browserslist-ua-parser

Parse User-Agent into browserslist's compatible format

What is it?

This is User-Agent parser, but unlike others, it only returns browser name and version in browserslist's format. This helps you create Custom Usage Data.

Installation

with npm

npm install browserslist-ua-parser

with yarn

yarn add browserslist-ua-parser

with pnpm

pnpm add browserslist-ua-parser

Usage

import { parseUA } from 'browserslist-ua-parser'

parseUA('Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36')
// { browser: 'chrome', version: '108' }

Notes

• This library categorized the browsers based on their layout engine instead of their real browser's name, like all browsers on iOS will return ios_saf (Because all browsers in iOS use Webkit), or Browsers based on Chromium, such as MiuiBrowser will return chrome.

  This because this library intentionally used for detecting features using Browserslist, and that is how Browserslist work.

• Chrome Android will be parsed as chrome instead of and_chr. This because Browserslist only work with last version on mobile browser (see this comment). This also applied to Firefox.
