platform-checker

Description

An ES module for checking which computing platform the script is executed in. For now it can check if it's running in Node.js, Deno or the browser.

Example

import {platform, platformVersion} from 'platform-checker'

console.log(platform, platformVersion)

Example output:

| Platforn | Output | | --- | --- | | Browser | Browser Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.90 Safari/537.36 | | Deno | Deno 1.8.3 | | Node.js | Node.js v15.13.0 |

How to use

Install using NPM

npm i platform-checker

Import the ES module into Node.js

import {platform} from 'platform-checker'

Import the ES module into the browser or Deno

import {platform} from '/node_modules/platform-checker/source/platformChecker.js'

Cumbersome? Consider using import maps so you can import it just like in Node.js. Also see the Deno specific documentation for import maps if using Deno.

Source code

Here is the full source code just to demonstrate how this works:

export const nodejs = (globalThis.Buffer && globalThis.process) ? process.version : undefined
export const deno = globalThis.Deno?.version?.deno
export const browser = globalThis.navigator?.userAgent

export const platform = (()=>{
  if (deno) return 'Deno'
  if (browser) return 'Browser'
  if (nodejs) return 'Node.js'
})()
export const platformVersion = deno || browser || nodejs

Have a happy day! ❤️
