Summary by CodeRabbit

• New Features
  • Added a Vue 3 integration for A/B tests, feature flags, and remote configuration, with typed composables for accessing reactive values.
  • Added server-side rendering support, including hydration of feature flags and remote configuration from server-loaded data.
  • Added setup and usage guidance for configuring the integration and using it in Vue applications.
• Bug Fixes
  • Persisted A/B test variants are reused only while they remain configured. If a saved variant is no longer available, a valid replacement is selected; the replacement is saved when cookies are enabled.

Walkthrough

Adds the @tryabby/vue package with a provider and typed composables for A/B tests, feature flags, and remote config. The integration supports client-side loading and server-provided initial data. The change also validates persisted test variants against configured variants.

Changes

Vue integration

Layer / File(s)	Summary
Client and provider lifecycle packages/vue/src/index.ts, packages/vue/package.json, packages/vue/tsconfig.json, packages/vue/tsup.config.ts, packages/vue/vite.config.ts, packages/vue/.gitignore, .changeset/add-vue-integration.md, packages/vue/README.md	Adds the package setup and configuration. createAbby creates an Abby client with cookie-backed stores. AbbyProvider initializes from initialData or loads project data after mounting, and provides client state to descendants.
Composable values and tracking packages/vue/src/index.ts, packages/vue/tests/*, packages/vue/README.md	Adds provider-checked composables for A/B tests, feature flags, and remote config. Test selections send PING and ACT events. Runtime, SSR, and type tests cover values, updates, and type errors.

Persisted variant validation

Layer / File(s)	Summary
Validate persisted test variants packages/core/src/index.ts, packages/core/tests/persisted-variants.test.ts	getTestVariant reuses a persisted value only when it matches a configured variant. Tests cover retention, replacement of removed variants, disabled cookies, and missing values.

Full details: Title check

Explanation

The title "feat(vue): add typed Vue 3 integration" matches the main change. The changeset adds a new @tryabby/vue package with a typed createAbby factory, provider, and composables for A/B tests, feature flags, and remote config. The title is short, specific, and uses a conventional commit prefix. Supporting changes in core (persisted variant handling) and tests are secondary and need not appear in the title.

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 8 files.

Resolution

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

- Around line 40-56: Validate persisted variants in core before accepting them
for selection: only reuse a persisted value when it matches a configured
variant, and treat any other value as absent so the existing selection and
cookie-consent logic applies. Locate the persisted-value check in the core
variant-selection flow; do not add this validation to the Vue cookieStorage
adapter.
