react-fingerprint

Utility for generating user fingerprints with one function.

Data points

* Browser vendor, language, useragent, plugins, capabilities (contacts, pdf, cookies), mimetypes, canvas, doNotTrack
* Device bars (menubar, toolbar etc), touchscreen, cpu, display sizes, ram, colour info
* Timezone
* Audio test
* Webgl info
* Fonts
* Math calculations (some of them differ ever so slightly between browsers)

Usage

``ts
import { getFingerprint, getRawFingerprint } from "react-fingerprint";
// const { getFingerprint, getRawFingerprint } = require("react-fingerprint") (cjs version)

const asyncFunc = async () => {
let fingerprint = await getFingerprint() // fingerprint id
let rawData = await getRawFingerprint() // raw data that is used to make the fingerprint
}
`

⚠️ Warning

This package relies entirely on browser APIs, so if you are using it with an SSR framework (example being Remix) then find a way to run it only client-side

$3

To run code client-side in Remix, you use the React useEffect function.

`js
import { getFingerprint } from "react-fingerprint"
import React, {useEffect} from "react"

export default function view() {
useEffect(() => {
(async () => { // as react-fingerprint returns promises, you will need to either wrap it in an async func or use .then()
let fingerprint = await getFingerprint()
})
})

return (


whatever


)
}
