+# @probat/react
+
+React SDK for Probat A/B testing. Automatic impression and click tracking with zero boilerplate.
+
+## Install
+
+```bash
+npm install @probat/react
+```
+
+## Quick Start
+
+Wrap your app root with the provider (Next.js App Router example):
+
+```tsx
+// app/providers.tsx
+"use client";
+import { ProbatProviderClient } from "@probat/react";
+
+export function Providers({ children }: { children: React.ReactNode }) {
+ return (
+
+ {children}
+
+ );
+}
+```
+
+Create a thin experiment wrapper — one per experiment:
+
+```tsx
+// components/CTAButton/CTAButton.experiment.tsx
+"use client";
+import { Experiment } from "@probat/react";
+import { CTAButton } from "./CTAButton";
+import { CTAButtonAI } from "./CTAButton.ai-v1";
+
+export function CTAButtonExperiment() {
+ return (
+ }
+ variants={{ ai_v1: }}
+ />
+ );
+}
+```
+
+That's it. Impressions (50% visible for 250ms) and clicks are tracked automatically.
+
+## Custom Metrics
+
+```tsx
+const { capture } = useProbatMetrics();
+capture("purchase", { revenue: 42 });
+```
+
+## Run the Example
+
+```bash
+cd packages/probat-react/example
+node mocks/server.ts & # mock API on :3001
+npx next dev # app on :3000
+```
+
+## Docs
+
+See [SPEC.md](./SPEC.md) for the full event schemas, assignment rules, dedupe logic, and edge cases.
