Closes #68
/claim #68

Summary

Adds the @tryabby/vue integration package under packages/vue, consuming @tryabby/core internally and providing full feature and TypeScript type parity with @tryabby/react.

Acceptance Criteria Checklist

  • Located inside packages/vue and named @tryabby/vue`n- [x] Consumes @tryabby/core internally (Abby, HttpService, AbbyEventType, storage keys, and config types)
  • Written in TypeScript with full generic type narrowing matching @tryabby/react`n- [x] useAbby: returns the user's currently selected variant (with optional lookup mapping) as well as the onAct callback
  • useFeatureFlag: returns the boolean value of the given feature flag
  • useRemoteConfig: returns the strongly-typed value (string,
    umber, �oolean, Record<string, unknown>) of the given remote config key
  • Includes both AbbyProvider component and AbbyPlugin Vue/Nuxt plugin alongside unit tests for both runtime behavior ( ests/useAbby.test.ts) and TypeScript types ( ests/types.test.ts)

Summary by CodeRabbit

  • New Features
    • Added a Vue 3 integration for Abby feature flags, A/B testing, and remote configuration.
    • Added composables, provider and plugin options, direct value getters, and devtools support.
    • Added cookie-backed persistence for test variants, feature flags, and remote-config values.
    • Providers and plugins can initialize with supplied data or load project data automatically.
    • Added package installation and usage documentation.

Merge Risk: 🟡 Moderate · up to f0c21

Configured A/B test cookie expiry is silently ignored, and the Vue plugin can accumulate subscriptions when one client is shared across SSR requests. Fix both before merging.

packages/vue/src/context.ts:86-89
🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Forward the configured test-cookie expiry.

When config.cookies.expiresInDays is set, the core test-storage wrapper passes it as a third set argument. This callback discards that argument, so TestStorageService.set uses its 365-day default instead. Accept and forward the storage options so the configured expiry takes effect.

Clean up the plugin subscription when the app is destroyed.

When one createAbby instance is shared across SSR requests, AbbyPlugin.install accumulates one callback per app. Each callback captures that app's dataRef, so app teardown does not release the reference. Retain and invoke the unsubscribe function at app lifetime end.
