Use as esm without cdn

[MentalGear]

Is it possible to use the library only on device without "phoning" to the cdn?

I just want to get a fingerprint to use, and it won't matter if accuracy drops.

Hello @MentalGear, you can use the Webpack/Rollup/NPM/Yarn installation method documented here.

# Install the package first:
npm i @fingerprintjs/fingerprintjs
# or
yarn add @fingerprintjs/fingerprintjs

import FingerprintJS from '@fingerprintjs/fingerprintjs'

// Initialize an agent at application startup.
const fpPromise = FingerprintJS.load()

;(async () => {
  // Get the visitor identifier when you need it.
  const fp = await fpPromise
  const result = await fp.get()
  console.log(result.visitorId)
})()

Thanks for the reply! So this won't trigger any telemetry to fingerprint.com and execute only locally?

Yes, if you set it up accordingly (see below), it won't send any requests.

const fpPromise = FingerprintJS.load({
  monitoring: false
})

Great ! Is there any indication available how much accuracy gets dropped with this method? I read on the main page, that the fingerprint method uses a mix of indicators, including users' IP address, which obviously wouldn't be available when running client-side only.

It's hard to quantify accuracy drop precisely. Without the updated library, once there's a new change introduced in specific browser that affects fingerprinting logic or entropy sources, it might affect accuracy. Needless to say, browsers are evolving quite fast these days. To take a picture you can check our release frequency.

Open source FingerprintJS and Fingerprint Pro are two different products. There are no IP addresses as an entropy source for open source FingerprintJS. For a full comparison check our documentation.

Thank you for the detailed and quick answer !
