vite-plugin-browserslist-useragent
A vite plugin wrapping browserslist-useragent-regexp which provides utility RegExps compiled by browserslist query to test browser useragent.
Simplest example: you can detect supported browsers on client-side.
- Create
.browserslistrc
config, for example like this:
last 2 versions
not dead
- Add plugin to
vite.config.*
:
// vite.config.ts
import SupportedBrowsers from 'vite-plugin-browserslist-useragent'
export default defineConfig({
plugins: [SupportedBrowsers(/* options */)],
})
- Import RegExp from virtual module:
import { browsersRegex } from 'virtual:supported-browsers'
if (browsersRegex.test(navigator.userAgent)) {
alert('Your browser is supported.')
}
Auto-generated virtual:supported-browsers
:
export const browsersRegex =
/Edge?\/(10[5-9]|1[1-9]\d|[2-9]\d\d|\d{4,})(\.\d+|)(\.\d+|)|Firefox\/(10[4-9]|1[1-9]\d|[2-9]\d\d|\d{4,})\.\d+(\.\d+|)|Chrom(ium|e)\/(10[5-9]|1[1-9]\d|[2-9]\d\d|\d{4,})\.\d+(\.\d+|)|Maci.* Version\/(15\.([6-9]|\d{2,})|(1[6-9]|[2-9]\d|\d{3,})\.\d+)([,.]\d+|)( Mobile\/\w+|) Safari\/|Chrome.+OPR\/(9\d|\d{3,})\.\d+\.\d+|(CPU[ +]OS|iPhone[ +]OS|CPU[ +]iPhone|CPU IPhone OS|CPU iPad OS)[ +]+(15[._]([6-9]|\d{2,})|(1[6-9]|[2-9]\d|\d{3,})[._]\d+)([._]\d+|)|Opera Mini|Android:?[ /\-](10[6-9]|1[1-9]\d|[2-9]\d{2}|\d{4,})(\.\d+|)(\.\d+|)|Mobile Safari.+OPR\/(6[4-9]|[7-9]\d|\d{3,})\.\d+\.\d+|Android.+Firefox\/(10[5-9]|1[1-9]\d|[2-9]\d\d|\d{4,})\.\d+(\.\d+|)|Android.+Chrom(ium|e)\/(10[6-9]|1[1-9]\d|[2-9]\d\d|\d{4,})\.\d+(\.\d+|)|Android.+(UC? ?Browser|UCWEB|U3)[ /]?(13\.([4-9]|\d{2,})|(1[4-9]|[2-9]\d|\d{3,})\.\d+)\.\d+|SamsungBrowser\/(1[7-9]|[2-9]\d|\d{3,})\.\d+|Android.+MQQBrowser\/(13(\.([1-9]|\d{2,})|)|(1[4-9]|[2-9]\d|\d{3,})(\.\d+|))(\.\d+|)|K[Aa][Ii]OS\/(2\.([5-9]|\d{2,})|([3-9]|\d{2,})\.\d+)(\.\d+|)/
