## How to Use

### 1. In React Components

```tsx
import { useThingService } from "@/hooks";
import { EffectProvider } from "@/context";

export function CourseList() {
  const { things: courses, loading } = useThingService("course", "group-123");

  if (loading) return <div>Loading...</div>;

  return (
    <ul>
      {courses.map((course) => (
        <li key={course._id}>{course.name}</li>
      ))}
    </ul>
  );
}

// Wrap app with provider
export function App() {
  return (
    <EffectProvider>
      <CourseList />
    </EffectProvider>
  );
}
```

### 2. In Astro Pages

```astro
---
import { ThingService } from "@/services";
import { ClientLayer } from "@/services/ClientLayer";
import { Effect } from "effect";

const courses = await Effect.runPromise(
  Effect.gen(function* () {
    const service = yield* ThingService;
    return yield* service.list("course", "group-123");
  }).pipe(Effect.provide(ClientLayer))
);
---

<h1>Courses</h1>
<ul>
  {courses.map((course) => (
    <li>{course.name}</li>
  ))}
</ul>
```

### 3. Using Effect Directly

```tsx
import { useEffectRunner } from "@/hooks";
import { ThingService } from "@/services";
import { Effect } from "effect";

export function CreateCourseForm() {
  const { run, loading } = useEffectRunner();

  const handleSubmit = async (data: CourseData) => {
    const program = Effect.gen(function* () {
      const service = yield* ThingService;
      const courseId = yield* service.create({
        type: "course",
        name: data.name,
        groupId: data.groupId,
        properties: data.properties,
      });
      return courseId;
    });

    const courseId = await run(program);
    if (courseId) {
      navigate(`/courses/${courseId}`);
    }
  };

  return <form onSubmit={handleSubmit}>...</form>;
}
```

## Files Summary

**Total New Files:** 14 TypeScript files
**Total Lines of Code:** 1,100+ lines
**Phases Complete:** 2-4 (DataProvider, Services, Hooks)
**Phases Remaining:** 5-10 (Integration, Migration, Testing, Deployment)

---

## Key Design Decisions

1. **DataProvider Interface First:** Defines contract before implementation
2. **Effect.ts for Services:** Type-safe error handling, composition
3. **React Hooks for UI:** Standard React patterns, easy adoption
4. **Stub Providers:** Ready for multiple backend implementations
5. **Dependency Injection:** Layer composition for testing + flexibility

## Lessons Learned (Cycle 1-40)

✅ **Cycle 011-020:** DataProvider interface design is elegant and enforces ontology
✅ **Cycle 021-030:** Effect.ts services are composable and type-safe
✅ **Cycle 031-040:** React hooks integrate seamlessly with Effect programs
