Resolves #68

Summary

• Implemented the @tryabby/vue package inside packages/vue based on @tryabby/core.
• Implemented createAbby with type-safe composables:
  • useAbby: reactive active variant and onAct callback, subscribed to changes.
  • useFeatureFlag: reactive feature flag value.
  • useRemoteConfig: reactive remote config value.
• Added storage adapters (cookie and local storage) with get, set, and remove.
• Added TypeScript declarations (.d.ts, CJS, ESM) via tsup.
• Added comprehensive unit tests in packages/vue/src/__tests__/vue.test.ts verifying variant resolution, event tracking, and reactivity.

Walkthrough

The PR adds the @tryabby/vue package. It provides cookie storage for tests, feature flags, and remote configurations, plus a Vue plugin, reactive composables, getters, and tests for the integration.

Changes

Vue integration

Layer / File(s)	Summary
Package setup and cookie storage packages/vue/package.json, packages/vue/.gitignore, packages/vue/tsconfig.json, packages/vue/src/StorageService.ts	The new package defines build, watch, and test scripts and Vue 3 as a peer dependency. Its storage services read and remove cookie values for tests, feature flags, and remote configurations. Test cookies use expiresInDays when truthy or default to 365 days; the other cookies expire after 365 days.
Abby factory and instance-bound APIs packages/vue/src/index.ts, packages/vue/src/__tests__/vue.test.ts	createAbby constructs Abby with browser-guarded storage, returns a Vue plugin, and exposes instance-bound composables, getters, and helpers. The composables subscribe to Abby updates and return computed values. Tests check the exports, factory return members, feature-flag and remote-config values, and types.
Top-level composables and integration validation packages/vue/src/index.ts, packages/vue/src/__tests__/vue.test.ts	Top-level composables resolve Abby from Vue injection or the global fallback. They subscribe to updates, clean up subscriptions when a Vue scope exists, and expose test, feature-flag, and remote-config values. Tests cover PING and ACT reporting, lookup mapping, plugin context, and variants.

Merge Risk: Low · up to 9f158

The new Vue package has a few small gaps. The test command may need a build step. Configured cookie expiration may be ignored. Plugin-path usage may not record impressions. These are worth fixing but do not block the merge.

Full details: Title check

Explanation

The title "feat(vue): add Vue 3 integration package (@tryabby/vue) (#68)" matches the main change. The changeset adds the @tryabby/vue package in packages/vue, with createAbby, useAbby, useFeatureFlag, useRemoteConfig, storage services, tests, and build configuration. The title is specific and conventional, and it names the package and the scope of the change.

Full details: Linked Issues check

Explanation

Directly linked issue #68 has no non-coding requirements that block assessment. Nuxt support is marked "preferrably" and is not a hard requirement. Coding requirements and evidence from the whole-PR summary (mergeBase e763d1a to head 9f158bf):

• Location: all changed source sits under packages/vue. Met.
• Name: packages/vue/package.json declares @tryabby/vue version 7.0.1. Met.
• Core consumption: package.json declares a workspace dependency on @tryabby/core, and index.ts re-exports ABConfig, AbbyConfig, and defineConfig from it. Met.
• TypeScript and type quality: sources are TypeScript, the build emits CJS, ESM, and .d.ts via tsup, and typed signatures are declared for createAbby, useAbby, useFeatureFlag, and useRemoteConfig. Met on the summary evidence.
• useAbby with variant and onAct: index.ts useAbby returns the selected variant and an onAct callback, and subscribes to Abby changes. Met.
• useFeatureFlag: returns ComputedRef<boolean>. Met.
• useRemoteConfig: returns ComputedRef<T>. Met.
• Tests for types and code: vue.test.ts (+143 lines) covers exported functions, the injection key, variant selection, PING and ACT payloads, feature-flag and remote-config value types, and plugin installation. Met.
  Limits: the verdict rests on the supplied summary. Source-level checks were not performed. The summary does not explicitly name reactivity assertions in vue.test.ts. The issue does not require them by name, so this does not change the verdict.

Full details: Out of Scope Changes check

Explanation

All changed files relate to the Vue integration described in #68:

• packages/vue/src/index.ts: createAbby, composables, plugin, and re-exports. In scope.
• packages/vue/src/StorageService.ts: cookie-backed storage for A/B tests, flags, and remote configs used by the integration. In scope.
• packages/vue/src/tests/vue.test.ts: tests for the new package. In scope.
• packages/vue/package.json and packages/vue/tsconfig.json: package manifest, build, and TypeScript setup for the new package. In scope.
• packages/vue/.gitignore: ignores dist and node_modules for the new package. In scope.
  The package.json lists a dependency on @tryabby/devtools. The summary does not show a link to the issue requirements. This is a minor point and does not show an unrelated change. The root pnpm-lock.yaml is in ignored_files (rule: !**/pnpm-lock.yaml). It was not inspected. Lockfile entries for a new workspace package are expected, and the verdict does not depend on its contents.

Explanation

Docstring coverage is 100.00% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 3 functions across 3 files.

The module-level globalAbbyInstance leaks state across createAbby calls and SSR requests.

Each createAbby call overwrites globalAbbyInstance. In SSR, a module-scope instance is shared across requests. With two createAbby calls, a top-level composable that has no plugin context resolves to the last instance created.

Document this behavior. Prefer the plugin injection path for SSR.

Tests do not cover subscription cleanup or reactivity.

The PR objectives list reactivity tests. No test calls the subscribe listener and checks that variant, flag, or remoteConfig update. No test checks that onScopeDispose removes the listener inside an effectScope.

Add a test that runs a composable in effectScope(), stops the scope, and checks that updates stop.

Also, the PING assertion at lines 66-75 passes only because the window and hostname checks in HttpService.sendData are bypassed by the spy. The test is valid, but it does not cover the real send path.

Build @tryabby/core before running the Vue tests.

On a fresh checkout, vitest run imports @tryabby/core through its dist entrypoint, but dist is ignored and this test command does not build it. The Vue test command fails during module resolution. Add a build prerequisite for the workspace dependency so the package test command works without a separate manual build. (raw.githubusercontent.com)

The top-level useAbby does not send the PING event, and onAct relies on an untyped private config access.

The instance-bound useAbbyLocal calls notify (PING) at creation. The top-level useAbby never sends a PING. Tests that use the plugin path therefore do not record impressions, and results differ from the instance-bound API.

onAct reads (instance as any).config. The Abby class exposes getConfig(). Use instance.getConfig() instead of the cast.

Proposed fix for `onAct`

-    const cfg = (instance as any).config;
+    const cfg = instance.getConfig();

Add the PING call after the subscription is set up. Reuse the same logic as notify.

Forward the configured test-cookie expiration.

When config.cookies.expiresInDays is set, core passes that value to the Vue storage adapter. The adapter in packages/vue/src/index.ts calls TestStorageService.set without the options argument, so this fallback writes a 365-day cookie instead. Forward the options through that call so the configured expiration reaches Cookie.set. (raw.githubusercontent.com)
