Summary

  • Adds Vue 3 integration (createAbby, AbbyProvider, useAbby, useFeatureFlag, useRemoteConfig) in packages/vue/src/context.ts wrapping @tryabby/core with reactive ComputedRef bindings and Vue provide/inject.

Fixes #68
/claim #68

Summary by CodeRabbit

  • New Features
    • Added Vue integration for accessing test variants, feature flags, and remote configuration values through composables.
    • Added a provider for sharing an Abby instance across Vue components.
    • Test variant results expose an onAct callback for recording actions.
    • Values update when subscribed configuration changes are received.

Walkthrough

This change adds a Vue integration that creates an Abby instance and provider. It exposes composables for test variants, feature flags, and remote config, and re-exports core configuration types and defineConfig.

Layer / File(s) Summary
Create the Vue context and composables

createAbby creates an Abby instance and provider. The composables return computed values that track supported instance updates. useAbby also returns an onAct callback.

Explanation

The title "feat(vue): add Vue 3 integration composable and provider (#68)" names the main change. The raw summary and objectives both describe a new Vue 3 integration in packages/vue/src/context.ts that adds createAbby, AbbyProvider, useAbby, useFeatureFlag, and useRemoteConfig. The title is specific, short, and follows a conventional commit style. It names the composable and provider, which are core parts of the change. The issue reference (#68) matches the linked issue.

Full details: Out of Scope Changes check

Explanation

The only change is the new file packages/vue/src/context.ts (+70 lines, no deletions). It implements the Vue integration that issue #68 requests and stays inside packages/vue, as the issue requires. It exports createAbby, AbbyProvider, useAbby, useFeatureFlag, useRemoteConfig, and re-exports core types and defineConfig. Each export maps to an issue requirement or supports one, so no unrelated change exists in the diff. The missing package.json and tests are unmet requirements, reported under linkedIssuesAssessment, not out-of-scope changes.

Full details: Linked Issues check

Explanation

Issue #68 has coding requirements. Several are met by the diff in packages/vue/src/context.ts: (1) useAbby returns a ComputedRef variant and an onAct method (ABTestReturnValue); (2) useFeatureFlag returns a ComputedRef<boolean> for a flag; (3) useRemoteConfig returns a ComputedRef for a remote config key; (4) the code is TypeScript and consumes @tryabby/core via createAbbyInstance and defineConfig. Two requirements are unmet. First, the package must be named @tryabby/vue. The file packages/vue/package.json does not exist at the reviewed head (git reports the path is absent), and the files listing for packages/vue contains only src/context.ts. No package name is defined. Second, the issue requires tests for the types and the code. The PR adds no test files under packages/vue, and the PR description reports no test results. Nuxt support is a preference only and is not assessed as a requirement.

Resolution

Add packages/vue/package.json with the name "@tryabby/vue", and declare the @tryabby/core and vue dependencies needed by src/context.ts. Add an entry point for the package if needed. Add automated tests under packages/vue that cover the runtime behavior of useAbby (variant and onAct), useFeatureFlag, and useRemoteConfig, and that check the exported types (for example with a type-level test such as expect-type or tsd, or a vitest typecheck).

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. 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 1 functions across 1 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Add a package manifest for @tryabby/vue in packages/vue.

The PR adds only packages/vue/src/context.ts. Without packages/vue/package.json, the directory is not a pnpm workspace package. Turbo does not build it, pnpm --filter @tryabby/vue finds no package, and pnpm publish cannot publish @tryabby/vue. Issue #68 requires this named package, so the integration cannot be installed or imported as @tryabby/vue.

Add a manifest that defines the package name and entrypoints, similar to packages/react/package.json. Declare the package's dependencies separately, because that change belongs to the imports concern.

Replace the core imports and method calls in context.ts. Keep onAct and send the ACT event from the Vue package.

@tryabby/core does not export createAbbyInstance or AbbyInstance, and its source has no __subscribe method. Line 2 does not compile against this core source. The optional call on line 15 also skips the subscription silently, so the computed values do not refresh when flags or remote config update.

The composables also call methods that the core Abby class does not define:

  • abby.getVariant (line 37): core defines getTestVariant at packages/core/src/index.ts:526.
  • instance.__subscribe?. (line 15): core defines subscribe at packages/core/src/index.ts:609.
  • abby.onAct (line 41): the inspected core class defines no onAct member. Keep onAct in ABTestReturnValue because issue #68 requires it. Send the ACT event from the Vue package, as packages/react/src/context.tsx does.
Suggested fix for the core API boundary

-import { createAbbyInstance, type AbbyConfig, type AbbyInstance, type ABConfig, defineConfig } from "@tryabby/core";
+import { Abby, type AbbyConfig, type ABConfig, defineConfig } from "@tryabby/core";
-  const instance: AbbyInstance<TConfig> = createAbbyInstance(config);
-  const AbbyKey: InjectionKey<AbbyInstance<TConfig>> = Symbol("AbbyContext");
+  const instance = new Abby(config);
+  const AbbyKey: InjectionKey<typeof instance> = Symbol("AbbyContext");
-  instance.__subscribe?.(() => {
+  instance.subscribe(() => {
     version.value += 1;
   });
-  function useInstance(): AbbyInstance<TConfig> {
+  function useInstance(): typeof instance {
-      return abby.getVariant(testName);
+      return abby.getTestVariant(testName);

Replace onAct on line 41 with a function that sends the ACT event. Use the variant computed value as selectedVariant. Import HttpService and AbbyEventType from the same module that packages/react/src/context.tsx uses. Keep the early return when no variant is selected.

Check the new Abby(config) generics before you commit the change. ABTestReturnValue depends on the test names inferred from TConfig.

Wrap the optional flags property in NonNullable before indexing.

TConfig["flags"] includes undefined because core AbbyConfig declares flags?. Indexing that type with [number] is invalid under strict: true. The error sits in the generic constraint, so it can fail type-checking for packages/vue/src/context.ts whenever that file is compiled with strict null checks. This matches the existing NonNullable use in useRemoteConfig.

Type useRemoteConfig with the configured value type.

useRemoteConfig returns ComputedRef<unknown>, so callers lose the value type. Core declares that type on getRemoteConfig, and the React integration keeps it. RemoteConfigValueStringToType is exported from @tryabby/core, and the key constraint already guarantees a RemoteConfigValueString value.
