Edge Runtime User Agent

The @edge-runtime/user-agent package gives some utilities on top of ua-parser-js .

Installation


npm install @edge-runtime/user-agent


pnpm add @edge-runtime/user-agent


yarn add @edge-runtime/user-agent


bun add @edge-runtime/user-agent

This package includes built-in TypeScript support.

Usage

Just call the exported .userAgentFromString method for getting the parsed data from an User-Agent HTTP header:


import { userAgentFromString } from '@edge-runtime/user-agent'
 
export default (request: Request) => {
  const userAgent = request.headers.get('user-agent')
  userAgentFromString(userAgent)
 
  return Response.json(userAgent(request))
  // => {
  //   browser: {
  //     major: '83',
  //     name: 'Chrome',
  //     version: '83.0.4103.116',
  //   },
  //   cpu: { architecture: 'amd64' },
  //   engine: {
  //     name: 'Blink',
  //     version: '83.0.4103.116',
  //   },
  //   isBot: false,
  //   os: {
  //     name: 'Windows',
  //     version: '10',
  //   },
  //   ua: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64)…'
  // }
}

or alternatively, you can call .userAgent and pass the Request instance:


import { userAgent } from '@edge-runtime/user-agent'
 
export default (request: Request) => {
  return Response.json(userAgent(request))
  // => {
  //   browser: {
  //     major: '83',
  //     name: 'Chrome',
  //     version: '83.0.4103.116',
  //   },
  //   cpu: { architecture: 'amd64' },
  //   engine: {
  //     name: 'Blink',
  //     version: '83.0.4103.116',
  //   },
  //   isBot: false,
  //   os: {
  //     name: 'Windows',
  //     version: '10',
  //   },
  //   ua: 'Mozilla/5.0 (Windows NT 10.0; Win64; x64)…'
  // }
}
