Adds the @tryabby/vue integration package in packages/vue consuming @tryabby/core with full TypeScript parity with @tryabby/react:
createAbby: Initializes @tryabby/core with cookie-backed TestStorageService, FlagStorageService, and RemoteConfigStorageService (SSR/Nuxt-safe when window is undefined).
Composables & Provider:
useAbby(name, lookupObject?): Returns { variant, onAct } with narrowed variant/lookup types and dispatches PING and ACT events.
useFeatureFlag(name) & useFeatureFlags(): Reactive feature flag accessors.
useRemoteConfig(name) & useRemoteConfigVariables(): Reactive remote config accessors with RemoteConfigValueStringToType type mapping.
AbbyProvider component and Vue install plugin method, plus getFeatureFlagValue, getRemoteConfig, getABTestValue, getABResetFunction, getVariants, updateUserProperties, and withDevtools.
Tests: Added runtime and expectTypeOf tests in packages/vue/tests/useAbby.test.ts.

Merge Risk: Moderate · previous review 6601b
The new Vue package's runtime tests are not actually executed under the current Vitest configuration, so regressions would pass unnoticed. Fix the test selection before merging. A narrow stale-state case in the provider should also be fixed.

- Line 212: Update the computed lookups in useFeatureFlag and useRemoteConfig to
use the core fallback lookup methods instead of directly dereferencing entries
that may be absent, while keeping both values reactive and honoring configured
defaults.
- Around line 143-147: Initialize selectedVariant in useAbby as an empty string
instead of reading a variant from dataRef or abby.getProjectData(); keep the
existing onMounted logic that loads the client variant and sends the ping.
- Around line 293-300: Ensure each Vue app or SSR request gets its own complete

withDevtoolsFunction exposes types from @tryabby/devtools. tsup leaves external library types out of the bundled declaration, but @tryabby/devtools is only a devDependency. TypeScript consumers can therefore fail to resolve the published declaration.

Scope the complete Abby instance per app or request.
When the same createAbby result is installed in multiple Vue apps with different initialData, the later install call replaces the shared state observed by earlier apps. This can affect SSR when one factory result is reused across requests.
A separate Vue ref alone does not fix this. abby.init() mutates the shared Abby instance and notifies every subscriber. Create a separate createAbby result for each app or request, or otherwise make the Abby instance request-scoped.
React has the same underlying issue. Its provider state is local, but providers created from one factory result subscribe to the same Abby instance.

Call the composables inside component setup.
This test calls useAbby without an active Vue component. inject then returns undefined, and useAbby throws when it reads dataRef.value. The package test run fails before the type assertions. Render a test component and call the composables in its setup function. (github.com)

Run the inference assertions through a typechecker.
The package test script runs vitest without typechecking, and the Vitest configuration does not enable typechecking. The type-test requirement is therefore not fulfilled. Add a typecheck command that includes packages/vue/tests/useAbby.test.ts in the package validation workflow.
