0.12.0

Minor Changes

• Add strictProxyHas configuration option for accurate namespace conflict detection (by @chadgauth in #692)

  Summary:

  This release adds a new configuration option strictProxyHas that enables accurate property existence checks using the in operator. This is required for scripts like FullStory that check for namespace conflicts when loaded via Google Tag Manager (GTM).

  Key Changes:

  • Add strictProxyHas?: boolean config option to enable accurate in operator behavior
  • Update window proxy's has trap to use Reflect.has() when strictProxyHas: true
  • Default is false for backwards compatibility
  • Add FullStory GTM integration test with production-ready snippet
  • Document the configuration and provide usage guide

  Usage:

  <script>
    partytown = {
      forward: ['FS.identify', 'FS.event'],
      strictProxyHas: true, // Enable for FullStory via GTM
    };
  </script>

  Backwards Compatibility:

  This is a non-breaking change. The default behavior remains unchanged (strictProxyHas: false), so existing implementations will continue to work without modifications.
