Summary

Adds the official Vue 3 & Nuxt integration package @tryabby/vue inside packages/vue with full feature and TypeScript parity with @tryabby/react:

  • Consumes @tryabby/core internally (Abby, HttpService, AbbyEventType, defineConfig, cookie storage services).
  • Provides createAbby returning:
    • useAbby(testName, lookupObject?) -> returns { variant, variantRef, onAct } and dispatches PING / ACT telemetry events.
    • useFeatureFlag(flagName) & useFeatureFlags() -> returns reactive typed feature flag values.
    • useRemoteConfig(key) & useRemoteConfigVariables() -> returns strongly typed remote config values (String, Number, Boolean, JSON).
    • AbbyProvider component & abbyPlugin Vue app plugin for SSR / Nuxt / SPA injection.
  • Includes runtime and TypeScript type tests in packages/vue/tests/useAbby.test.ts.

Closes #68
/claim #68

Merge Risk: High · up to b5fca

The new Vue package currently cannot pass CI because the lockfile is missing its entry and two of its tests fail on a core type that doesn't exist. Some composables can also return stale values, and the README quick start doesn't type-check. These should be fixed before merging.

Full details: Title check

Explanation

The title names the main change: adding the @tryabby/vue integration package with composables and tests. The raw summary confirms a new package with createAbby, composables for tests, feature flags and remote config, an AbbyProvider, a plugin, and Vue tests. The title does not mention the Nuxt support, and the '(#68)' suffix refers to the linked issue, which is acceptable. The title is specific and relevant, so the check passes.

Full details: Linked Issues check

Explanation

Issue #68 is the only directly linked issue, and it is open, so its coding requirements apply.

Package location and name: The head contains packages/vue/package.json with "name": "@tryabby/vue". The package sits inside packages/vue, as required.

Core consumption: packages/vue/package.json lists @tryabby/core as workspace:* in dependencies. StorageService.ts and context.ts use core storage keys and the Abby class, as described in the change summary.

TypeScript and types: The package uses TypeScript (src/context.ts, src/StorageService.ts, src/index.ts, tsconfig.json). It exports typed createAbby, ABTestReturnValue, and re-exports ABConfig, AbbyConfig, and defineConfig. tests/useAbby.test.ts includes compile-time type assertions for variant, mapped-variant, flag, and remote-config types.

useAbby: createAbby returns useAbby(testName, lookupObject?), which returns { variant, variantRef, onAct }. This covers the request for the selected variant and onAct.

useFeatureFlag: useFeatureFlag and useFeatureFlags return reactive typed flag values. This covers the flag requirement.

useRemoteConfig: useRemoteConfig and useRemoteConfigVariables return typed remote config values. The issue text for this bullet repeats the feature-flag wording. The PR implements remote config, which matches the bullet name and the issue description.

Tests: tests/useAbby.test.ts contains runtime tests for variant selection, ACT event data, flag and remote-config values, and type tests. This covers the test requirement.

Nuxt: The issue says Nuxt is preferred, not required. The PR describes SSR and Nuxt injection through abbyPlugin and AbbyProvider. Nuxt behavior was not separately verified, but it is not a stated requirement.

Basis: This verdict relies on the whole-PR change summary and the head file listing and package.json. The test file and context.ts were not read line by line. The summary describes their content.

Full details: Out of Scope Changes check

Explanation

The whole-PR file list at head contains only files under packages/vue: README.md, package.json, src/StorageService.ts, src/context.ts, src/index.ts, tests/useAbby.test.ts, tsconfig.json, tsup.config.ts, and vite.config.ts. No file outside the package changes.

Each file supports the new package:

  • src/StorageService.ts, src/context.ts, src/index.ts: implement the package API.
  • tests/useAbby.test.ts: tests the API, as the issue requires.
  • package.json, tsconfig.json, tsup.config.ts, vite.config.ts: build and test configuration for the new package.
  • README.md: documents the new package.

No change is unrelated to issue #68. The dev dependency @tryabby/devtools is a workspace package used by tooling. It does not change other packages.

Full details: Docstring Coverage

Explanation

No eligible functions found in the changed files. Skipping docstring coverage check. 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 0 functions across 6 files.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Build @tryabby/core before running the Vue tests.

On a fresh checkout, vitest run imports @tryabby/core through packages/vue/tests/useAbby.test.ts. Core exports dist/index.js and dist/index.mjs, but those files require a build. The root test task does not build dependencies first, so the Vue test command cannot resolve core. Add the build prerequisite to the test workflow. (raw.githubusercontent.com)

Inline comments:
Review comments at @packages/vue/package.json:
- Around line 1-3: Add the missing packages/vue importer to the pnpm lockfile by
regenerating it with pnpm 9.9.0, ensuring its dependency entries match the Vue
package manifest so frozen-lockfile installs can proceed.

Review comments at @packages/vue/README.md:
- Line 16: Update the quick-start call to defineConfig to pass both required
arguments: put projectId and currentEnvironment in the first object, and
environments, flags, tests, and remoteConfig in the second.

Review comments at @packages/vue/src/context.ts:
- Around line 216-220: Update the object returned by useAbby so variant stays
reactive as variantRef changes, using a getter backed by variantRef or clearly
documenting that consumers must use variantRef for reactive updates.
- Around line 223-226: Update useFeatureFlag and the corresponding remote-config
composable to handle missing entries in project data without throwing. Resolve
absent values using the existing configured override and default behavior,
preserving those precedence rules and leaving present-entry behavior unchanged.
- Around line 77-81: Update the test storage set wrapper to accept the optional
StorageServiceOptions argument and pass it through to TestStorageService.set,
preserving configured cookie expiry; import the type from @tryabby/core.
- Around line 110-132: Update ensureGlobalSubscription to refresh globalDataRef
from abby.getProjectData() when establishing the first subscription, so
standalone composables receive current project data; preserve the subscription
callback’s updates for subsequent changes.

Review comments at @packages/vue/tests/useAbby.test.ts:
- Around line 129-166: Ensure the type assertions in the test using createAbby,
useAbby, useFeatureFlag, and useRemoteConfig are checked by the project’s Vitest
typecheck workflow rather than relying on vitest run; configure or invoke that
workflow for this test. Also correct the remote-config Boolean schema to use the
established boolean schema representation, preserving the intended boolean
inference assertion.
- Around line 97-127: Update the remote-config tests to use the supported JSON
type instead of Boolean, which Core rejects. In the runtime test, change the
promo configuration and value to JSON, then assert the returned object; also
update the related type assertion to expect a JSON object. Keep the tests
focused on supported remote-config types.

Update the lockfile for the Vue package.

The lockfile has no packages/vue importer. CI installs with frozen-lockfile mode, so the install fails before the package build and tests. Regenerate and commit the lockfile with pnpm 9.9.0.

Pass both arguments to defineConfig.

The re-exported defineConfig requires dynamicConfig and config. This quick start passes one object, so TypeScript reports a missing argument. Put projectId and currentEnvironment in the first object. Put environments, flags, tests, and remoteConfig in the second. (raw.githubusercontent.com)

Forward the options argument in the test storage set wrapper.

Core passes cookies.expiresInDays to the wrapper, but the wrapper drops it. Test cookies therefore use the 365-day default instead of a configured nonzero expiry.

Refresh global data when subscribing.

If __abby__.init() runs before the first standalone composable call, globalDataRef retains the pre-init values. The feature-flag test returns false for darkMode instead of true. Valid remote-config values can also remain at their defaults until another notification.

Suggested fix

       abby.subscribe((newData) => {
         globalDataRef.value = newData;
       });
+      globalDataRef.value = abby.getProjectData();

useAbby returns a non-reactive variant.

variant: variantRef.value reads the value once at call time. useAbby is called inside setup. The variant will not update when project data loads later, for example after AbbyProvider calls loadProjectData on mount. Templates that use variant keep the stale value. The reactive variantRef is available, but the primary field does not use it. Document that consumers must use variantRef for reactivity. You can also return a getter-based object.

Handle missing flag and remote config entries.

If project data omits a configured name, either composable can throw a TypeError. Use fallbacks that preserve configured overrides and defaults.

Replace the unsupported Boolean remote config type.

Core rejects "Boolean" during type checking and throws during construction. Both tests stop before their assertions. Use "JSON" to test a supported type.

assertType has no effect at runtime.

assertType is a no-op at runtime. vitest run does not type-check. These assertions do not verify types unless the vitest typecheck mode runs them. Also, the "Boolean" remote config type here has the same schema problem. Run vitest --typecheck, or add expectTypeOf tests with a typecheck config.

Review comment at @packages/vue/tests/useAbby.test.ts around lines 129 - 166:
Ensure the type assertions in the test using createAbby, useAbby,
useFeatureFlag, and useRemoteConfig are checked by the project’s Vitest
typecheck workflow rather than relying on vitest run; configure or invoke that
workflow for this test. Also correct the remote-config Boolean schema to use the
established boolean schema representation, preserving the intended boolean
inference assertion.
