device-uuid's Issues

Duplicate UUID generated for different devices

I have used this package in my web application to generate device specific uuid. But after checking multiple records, UUID's seem to be duplicating even when users are using different devices.

Generation of unique id for each device

I have created the uuid using this method
var uuid = du.hashMD5(dua.join(':'));
Now this one return unique id for chrome but in firefox its returning different id. Is there is any possibility to create UUID that should be unique for all the client browser.

DeviceUUID is not a constructor

i using this library for my project in react js
and how to using this library?

ReferenceError: navigator is not defined

DeviceID from a browser and then from an Android app

Let's say, I've run the script run in a mobile browser thus generating a DeviceID. Is there an API of Android to generate the same DeviceID from within a mobile app?

I need to pass DeviceID from a browser to my app.

DeviceUUID is not a constructor

can someone help with this error? I am facing this error while running a desktop app build with js, svelte and go.

Nice - Some general questions :)

Hi there. This is a great tool you have made.

1. Has it been used in production and what is your experience with it?

2. What works well and what does not work well?

3. Do you have any suggestions on how to configure it the bestway?

4. Do you think there are certain things at the end user that affect the result over time?

5. Is there a difference in the result before and after the user updates hes browser version?
   is the browser version also included in generating the uuid?

Thanks

ReferenceError: navigator is not defined in angular universal

hi
when run project in ssr
with command : npm run dev:ssr
get same error:

return new DeviceUUID(navigator.userAgent);
                        ^
ReferenceError: navigator is not defined

im using a mock browser , in server.ts file :

const MockBrowser = require('mock-browser').mocks.MockBrowser;
const mock = new MockBrowser();
global['navigator'] = mock.getNavigator();
global['window'] = mock.getWindow();
global['document'] = mock.getDocument();

thanks

NPM package please

Why bower? We want NPM as well.

OS X Safari – wrong OS

There is a browser-specific issue with Device ID generation for Mac.

Conditions: Apple Laptop with Mac OS X Yosemite (10.10) installed, having latest Chrome (55.0) and Safari 9.1. These browser report different OS version in UserAgent string.
Chrome: OS X 10_10 (correct)
Safari: OS X 10_11 (incorrrect)

I know nothing about company's politics regarding OS and browser versions and upgrades and if this issue can be reproduced again on other devices.

Compatibility with Vite

Hi, biggora
I am trying to use device-uuid with Vite react project.
When developing stage, it works well, but it is not working with production build.
I alwasys get this error message: "DeviceUUID is not contructor".
I hope you to resolve this as soon as possible.

No unique Id on euqal device models

Hi,

first of all i thought that i really get unique ids..

Lastly i tried to get the UUID on two devices which are equal (same manufacture, model, software version,..), then i recognized that i get the same UUID on both devices :(

For node js

Can I use this library in node.js?
