6. Offline Learning Support

// Download content for offline access
const OfflineManager = {
  downloadCourse: async (courseId) => {
    const course = await api.getCourse(courseId);

    // Download videos
    for (const section of course.curriculum) {
      for (const lesson of section.lessons) {
        if (lesson.type === 'video') {
          await downloadVideo(lesson.content.videoUrl, lesson.lessonId);
        }
      }
    }

    // Save course data
    await database.offline.saveCourse(course);

    showSuccess('Course downloaded for offline access');
  },

  getOfflineCourses: async () => {
    return await database.offline.getCourses();
  },

  syncProgress: async () => {
    // Sync offline progress when back online
    const pendingProgress = await database.offline.getPendingSync();

    for (const progress of pendingProgress) {
      await api.syncProgress(progress);
      await database.offline.markSynced(progress.id);
    }
  }
};

// Offline course viewer
const OfflineCourseViewer = ({ courseId }) => {
  const [course, setCourse] = useState(null);
  const [isOffline, setIsOffline] = useState(false);

  useEffect(() => {
    loadCourse();
    checkNetworkStatus();
  }, []);

  const loadCourse = async () => {
    // Try to load from offline storage first
    let courseData = await database.offline.getCourse(courseId);

    if (!courseData && navigator.onLine) {
      // Load from API if online
      courseData = await api.getCourse(courseId);
    }

    setCourse(courseData);
  };

  return (
    <View>
      {isOffline && (
        <Banner type="info">
          You're offline. Progress will sync when connected.
        </Banner>
      )}

      <CourseViewer course={course} offline={isOffline} />
    </View>
  );
};
