obsidiahq / cuid2 Goto Github PK

Hi,

Thank you for your package, very helpful.
I tried to include it inside a mobile/web project but I had an incompatibility with the code for the web platform.

The problem

_createFingerprint() inside cuid2_base.dart use Platform.localHostname; and pid.

• dart:io and Platform.localHostname, I successfully replace it with universal_io
• but I'm concern about the pid that I cannot simulate in a distributed system for a browser.

do you have any recommendation or sample for web integration please ?

Do you think that replace it for web by a Math.random is enough like said that inside: https://github.com/paralleldrive/cuid2/blob/6c64c5d118885eaef9e7594de4416dc4945e3460/src/index.js#L50

a simple fix will in cuid2_base.dart:

import 'package:universal_io/io.dart';
...
 String _createFingerprint() {
    final hostname = Platform.localHostname;
    final version = Platform.operatingSystemVersion;
    final os = Platform.operatingSystem;
    seed = kIsWeb ? (_random.nextDouble() * 36).floor() : pid;
    final fingerprint = '${_pad(seed.toRadixString(36), 3)}$hostname$version$os';
    final entropy = _createEntropy(length: _entropyLength);
    final sourceString = '$fingerprint$entropy';

    return _hash(sourceString).substring(0, _entropyLength);
  }

and with that the web platform will supported.

Best regards,

Alexandre
