feat(vue): add typed reactive integration with isolated providers - #210
Vue: 10 tests passed, including actual core reactivity, PING/ACT arguments, dynamic names, subscription cleanup, provider isolation, consent/persistence, fetch fallback, server rendering and real SSR markup hydration.
Public type checks include negative cases for unknown names, incomplete variant mappings and incorrect remote-config value types.
Core: 29 tests passed.
Core and Vue CJS/ESM/declaration builds passed.
Biome and git diff checks passed.
Lockfile adds only the new importer and reachable dependency records (194 added lines); existing importers are unchanged. Filtered frozen installation passed.
This is not a claim that all application workspaces, every Vue version, Nuxt deployment or a real hosted Abby project were tested. Existing unrelated peer warnings are not fixed by this PR.
The video runs the real Vue package and core using synthetic initial data: variant selection, flag toggle, string/number configuration and ACT click. Playwright assertions passed at 1280x950 and 390x844, with no page errors or external requests, a loaded brand asset and no horizontal overflow.
The core's localhost event suppression remains in effect; network event argument coverage is in the unit tests, not a claim of production analytics delivery.
Boundaries
Variants are undefined until mount/data readiness to keep SSR hydration deterministic. Core development-only overrides remain development-only. A dedicated Nuxt module and optional Vue devtools panel are not included; the README describes a provider/initialData approach for Nuxt. Generated dist files and the demo video are not part of the code branch.

loadProjectData. Preserve the provider’s existing readiness and error-reporting
behavior.

Walkthrough
Adds the @tryabby/vue package with a typed createAbby API, provider, and composables for tests, feature flags, and remote configuration. The provider supports initial data, cookie storage, project-data loading, and per-provider client state. Core initialization now allows callers to defer browser cookie overrides; overrides remain enabled by default.

Defines the Vue package API and provider. The provider creates an isolated client, handles cookie storage and optional initial data, and loads project data when needed. Core initialization can defer cookie overrides through an optional parameter, which defaults to enabled.
Reactive composables packages/vue/src/index.ts
Adds composables for test variants and ACT/PING events, feature flags, remote configuration, client access, and readiness.
Examples and validation packages/vue/README.md, packages/vue/examples/*, packages/vue/src/tests/*
Adds setup and usage documentation, a Vue demo, integration and SSR tests, and compile-time checks for public types.

Merge Risk: Low · previous review 880e4
A malformed browser cookie can leave a provider unready, and a fresh direct package build requires a prior core build. Both risks are bounded and have workarounds.

Explanation
The title "feat(vue): add typed reactive integration with isolated providers" matches the main change. The PR adds the new @tryabby/vue package, which provides typed reactive composables and per-provider isolation. The title does not mention the small core change to Abby.init (the applyLocalOverrides parameter), but that is a secondary detail.
Full details: Linked Issues check
Explanation
Issue #68 requires a TypeScript package in packages/vue named @tryabby/vue that consumes @tryabby/core. It requires useAbby, useFeatureFlag, and useRemoteConfig, with code and type tests. The PR adds these APIs, core integration, strict TypeScript configuration, runtime tests, and negative public-type tests. The preferred Nuxt support is not a mandatory acceptance criterion.
Full details: Out of Scope Changes check
Explanation
The changes support the Vue integration in Issue #68. The package code, documentation, example, build configuration, changeset, tests, and the core initialization option support the required APIs, reactivity, typing, and SSR behavior. No unrelated product-area change is shown. A dedicated Nuxt module and Vue devtools panel are explicitly excluded and are not required by the issue.

Defer browser cookie overrides until after hydration.
Abby.init applies document.cookie before the provider renders, and the provider applies it again. A ready gate would avoid the hydration mismatch by replacing the flag with a placeholder, but it would violate the SSR contract that renders the initialData flag value. Defer the cookie application from Abby.init until onMounted, while keeping initialData available during SSR and the initial hydration render.
- if (props.initialData) client.init(props.initialData);- if (typeof document !== "undefined")- client.setLocalOverrides(document.cookie);+ if (props.initialData) client.init(props.initialData, false);
...
onMounted(async () => {
mounted.value = true;
+ if (typeof document !== "undefined")+ client.setLocalOverrides(document.cookie);
if (props.initialData) return;

Addressed the three review findings in 880e485 (Codex AI-assisted). Added a real SSR-to-browser cookie mismatch regression: it failed with a hydration mismatch before the fix and now passes. Core init gains an optional applyLocalOverrides parameter defaulting to true; the Vue provider defers browser overrides until mounted and refreshes computed state. Vue test/typecheck scripts now build core first. Validation: Vue 11/11 tests, core 29/29 tests, typecheck, Vue CJS/ESM/DTS build, Biome and diff check pass. No cloud deployment or payment verification is claimed.

Addressed follow-up findings in 92df2c8 (Codex AI-assisted). The cookie regression reproduced URIError before the fix; parsing now skips malformed name/value pairs while preserving valid neighbors, and provider override errors cannot bypass project loading. Added core and actual Vue loading regressions. Direct Vue build now builds core first, matching test/typecheck prerequisites. Validation: Vue 12/12, core 30/30, typecheck, CJS/ESM/DTS build, Biome (9 files), diff check pass. No new clone, full-workspace or cloud deployment validation is claimed.

Summary
Adds an independent @tryabby/vue package on current main, consuming the existing @tryabby/core.
No competing contributor implementation was copied. This work was prepared and tested with Codex AI assistance.
Validation
Windows / Node 24.3.0 / repository pnpm 9.9.0:
This is not a claim that all application workspaces, every Vue version, Nuxt deployment or a real hosted Abby project were tested. Existing unrelated peer warnings are not fixed by this PR.

The core's localhost event suppression remains in effect; network event argument coverage is in the unit tests, not a claim of production analytics delivery.
Boundaries
Variants are undefined until mount/data readiness to keep SSR hydration deterministic. Core development-only overrides remain development-only. A dedicated Nuxt module and optional Vue devtools panel are not included; the README describes a provider/initialData approach for Nuxt. Generated dist files and the demo video are not part of the code branch.
