Component Library¶

UI Components Architecture¶

Our component library follows atomic design principles:

Atoms (Basic Building Blocks)¶

// components/ui/Button.tsx
interface ButtonProps extends React.ButtonHTMLAttributes<HTMLButtonElement> {
  variant?: 'primary' | 'secondary' | 'outline' | 'ghost'
  size?: 'sm' | 'md' | 'lg'
  loading?: boolean
}

export const Button: React.FC<ButtonProps> = ({
  variant = 'primary',
  size = 'md',
  loading = false,
  children,
  className,
  ...props
}) => {
  return (
    <button
      className={cn(
        buttonVariants({ variant, size }),
        loading && 'opacity-50 cursor-not-allowed',
        className
      )}
      disabled={loading}
      {...props}
    >
      {loading && <Spinner className="mr-2" />}
      {children}
    </button>
  )
}

Molecules (Component Combinations)¶

// components/ui/FileUpload.tsx
interface FileUploadProps {
  onUpload: (file: File) => Promise<void>
  accept?: string
  maxSize?: number
  multiple?: boolean
}

export const FileUpload: React.FC<FileUploadProps> = ({
  onUpload,
  accept,
  maxSize,
  multiple = false
}) => {
  const [dragActive, setDragActive] = useState(false)
  const [uploading, setUploading] = useState(false)

  const handleDrop = useCallback(async (e: React.DragEvent) => {
    e.preventDefault()
    setDragActive(false)

    const files = Array.from(e.dataTransfer.files)
    for (const file of files) {
      if (validateFile(file, accept, maxSize)) {
        setUploading(true)
        await onUpload(file)
        setUploading(false)
      }
    }
  }, [onUpload, accept, maxSize])

  return (
    <div
      className={cn(
        "border-2 border-dashed rounded-lg p-6 text-center",
        dragActive ? "border-primary bg-primary/5" : "border-gray-300",
        uploading && "opacity-50"
      )}
      onDrop={handleDrop}
      onDragOver={(e) => e.preventDefault()}
      onDragEnter={() => setDragActive(true)}
      onDragLeave={() => setDragActive(false)}
    >
      <Upload className="mx-auto h-12 w-12 text-gray-400" />
      <p className="mt-2 text-sm text-gray-600">
        Drop files here or click to browse
      </p>
      <input
        type="file"
        accept={accept}
        multiple={multiple}
        className="hidden"
        onChange={handleFileSelect}
      />
    </div>
  )
}

Organisms (Complex Components)¶

// components/auth/LoginForm.tsx
interface LoginFormProps {
  onSuccess?: () => void
  redirectTo?: string
}

export const LoginForm: React.FC<LoginFormProps> = ({
  onSuccess,
  redirectTo = '/'
}) => {
  const { login } = useAuth()
  const navigate = useNavigate()

  const form = useForm<LoginSchema>({
    resolver: zodResolver(loginSchema),
    defaultValues: {
      username: '',
      password: ''
    }
  })

  const onSubmit = async (data: LoginSchema) => {
    try {
      await login(data)
      onSuccess?.()
      navigate(redirectTo)
    } catch (error) {
      form.setError('root', {
        message: 'Invalid username or password'
      })
    }
  }

  return (
    <Card className="w-full max-w-md">
      <CardHeader>
        <CardTitle>Sign In</CardTitle>
        <CardDescription>
          Enter your credentials to access your account
        </CardDescription>
      </CardHeader>
      <CardContent>
        <Form {...form}>
          <form onSubmit={form.handleSubmit(onSubmit)} className="space-y-4">
            <FormField
              control={form.control}
              name="username"
              render={({ field }) => (
                <FormItem>
                  <FormLabel>Username</FormLabel>
                  <FormControl>
                    <Input placeholder="Enter your username" {...field} />
                  </FormControl>
                  <FormMessage />
                </FormItem>
              )}
            />
            <FormField
              control={form.control}
              name="password"
              render={({ field }) => (
                <FormItem>
                  <FormLabel>Password</FormLabel>
                  <FormControl>
                    <Input type="password" placeholder="Enter your password" {...field} />
                  </FormControl>
                  <FormMessage />
                </FormItem>
              )}
            />
            <Button type="submit" className="w-full" loading={form.formState.isSubmitting}>
              Sign In
            </Button>
          </form>
        </Form>
      </CardContent>
    </Card>
  )
}

State Management¶

Zustand Store Architecture¶

We use Zustand for simple, efficient state management:

Authentication Store¶

// store/auth.ts
interface AuthState {
  user: User | null;
  token: string | null;
  isAuthenticated: boolean;
  isLoading: boolean;
}

interface AuthActions {
  login: (credentials: LoginCredentials) => Promise<void>;
  logout: () => void;
  refreshToken: () => Promise<void>;
  updateProfile: (data: UpdateProfileData) => Promise<void>;
}

export const useAuthStore = create<AuthState & AuthActions>((set, get) => ({
  // State
  user: null,
  token: localStorage.getItem("access_token"),
  isAuthenticated: false,
  isLoading: false,

  // Actions
  login: async (credentials) => {
    set({ isLoading: true });
    try {
      const response = await authAPI.login(credentials);
      const { access_token, user } = response.data;

      localStorage.setItem("access_token", access_token);
      set({
        user,
        token: access_token,
        isAuthenticated: true,
        isLoading: false,
      });
    } catch (error) {
      set({ isLoading: false });
      throw error;
    }
  },

  logout: () => {
    localStorage.removeItem("access_token");
    set({
      user: null,
      token: null,
      isAuthenticated: false,
    });
  },

  refreshToken: async () => {
    try {
      const response = await authAPI.refresh();
      const { access_token } = response.data;

      localStorage.setItem("access_token", access_token);
      set({ token: access_token });
    } catch (error) {
      get().logout();
      throw error;
    }
  },

  updateProfile: async (data) => {
    const user = await userAPI.updateProfile(data);
    set({ user });
  },
}));

UI State Store¶

// store/ui.ts
interface UIState {
  theme: "light" | "dark" | "system";
  sidebarOpen: boolean;
  notifications: Notification[];
}

interface UIActions {
  setTheme: (theme: UIState["theme"]) => void;
  toggleSidebar: () => void;
  addNotification: (notification: Omit<Notification, "id">) => void;
  removeNotification: (id: string) => void;
}

export const useUIStore = create<UIState & UIActions>((set, get) => ({
  // State
  theme: (localStorage.getItem("theme") as UIState["theme"]) || "system",
  sidebarOpen: true,
  notifications: [],

  // Actions
  setTheme: (theme) => {
    localStorage.setItem("theme", theme);
    set({ theme });
  },

  toggleSidebar: () => {
    set((state) => ({ sidebarOpen: !state.sidebarOpen }));
  },

  addNotification: (notification) => {
    const id = Math.random().toString(36).substr(2, 9);
    set((state) => ({
      notifications: [...state.notifications, { ...notification, id }],
    }));

    // Auto-remove after delay
    setTimeout(() => {
      get().removeNotification(id);
    }, notification.duration || 5000);
  },

  removeNotification: (id) => {
    set((state) => ({
      notifications: state.notifications.filter((n) => n.id !== id),
    }));
  },
}));

API Integration¶

Type-Safe API Client¶

We generate TypeScript types from the backend OpenAPI schema:

# Generate types from backend API
cd frontend
pnpm run generate:types

API Client Configuration¶

// lib/api/client.ts
import axios from "axios";
import { useAuthStore } from "@/store/auth";

const API_BASE_URL =
  import.meta.env.VITE_API_URL || "http://localhost:8000/api/v1";

export const apiClient = axios.create({
  baseURL: API_BASE_URL,
  timeout: 10000,
  headers: {
    "Content-Type": "application/json",
  },
});

// Request interceptor for authentication
apiClient.interceptors.request.use((config) => {
  const token = useAuthStore.getState().token;
  if (token) {
    config.headers.Authorization = `Bearer ${token}`;
  }
  return config;
});

// Response interceptor for error handling
apiClient.interceptors.response.use(
  (response) => response,
  async (error) => {
    if (error.response?.status === 401) {
      const authStore = useAuthStore.getState();
      try {
        await authStore.refreshToken();
        // Retry the original request
        return apiClient.request(error.config);
      } catch (refreshError) {
        authStore.logout();
        window.location.href = "/login";
      }
    }
    return Promise.reject(error);
  },
);

API Service Modules¶

// lib/api/auth.ts
export const authAPI = {
  login: (credentials: LoginCredentials) =>
    apiClient.post<AuthResponse>("/auth/login", credentials),

  register: (data: RegisterData) =>
    apiClient.post<UserResponse>("/auth/register", data),

  refresh: () => apiClient.post<AuthResponse>("/auth/refresh"),

  logout: () => apiClient.post("/auth/logout"),

  requestPasswordReset: (email: string) =>
    apiClient.post("/auth/password-reset-request", { email }),

  confirmPasswordReset: (data: PasswordResetData) =>
    apiClient.post("/auth/password-reset-confirm", data),
};

// lib/api/users.ts
export const userAPI = {
  getProfile: () => apiClient.get<UserResponse>("/users/me"),

  updateProfile: (data: UpdateProfileData) =>
    apiClient.put<UserResponse>("/users/me", data),

  getUser: (id: string) => apiClient.get<UserResponse>(`/users/${id}`),

  listUsers: (params?: ListUsersParams) =>
    apiClient.get<UsersListResponse>("/users", { params }),
};

Routing System¶

Route Configuration¶

// router.tsx
import { createBrowserRouter } from 'react-router-dom'
import { Layout } from '@/components/layout/Layout'
import { ProtectedRoute } from '@/components/auth/ProtectedRoute'

export const router = createBrowserRouter([
  {
    path: '/',
    element: <Layout />,
    children: [
      {
        index: true,
        element: <Home />
      },
      {
        path: 'login',
        element: <Login />
      },
      {
        path: 'register',
        element: <Register />
      },
      {
        path: 'dashboard',
        element: (
          <ProtectedRoute>
            <Dashboard />
          </ProtectedRoute>
        )
      },
      {
        path: 'profile',
        element: (
          <ProtectedRoute>
            <Profile />
          </ProtectedRoute>
        )
      },
      {
        path: 'uploads',
        element: (
          <ProtectedRoute>
            <Uploads />
          </ProtectedRoute>
        )
      }
    ]
  }
])

Protected Routes¶

// components/auth/ProtectedRoute.tsx
interface ProtectedRouteProps {
  children: React.ReactNode
  requiredRole?: string
}

export const ProtectedRoute: React.FC<ProtectedRouteProps> = ({
  children,
  requiredRole
}) => {
  const { isAuthenticated, user, isLoading } = useAuthStore()
  const location = useLocation()

  if (isLoading) {
    return <LoadingSpinner />
  }

  if (!isAuthenticated) {
    return <Navigate to="/login" state={{ from: location }} replace />
  }

  if (requiredRole && user?.role !== requiredRole) {
    return <Navigate to="/unauthorized" replace />
  }

  return <>{children}</>
}

Testing Strategy¶

Unit Testing with Vitest¶

// tests/components/Button.test.tsx
import { render, screen, fireEvent } from '@testing-library/react'
import { describe, it, expect, vi } from 'vitest'
import { Button } from '@/components/ui/Button'

describe('Button Component', () => {
  it('renders with correct text', () => {
    render(<Button>Click me</Button>)
    expect(screen.getByText('Click me')).toBeInTheDocument()
  })

  it('calls onClick handler when clicked', () => {
    const handleClick = vi.fn()
    render(<Button onClick={handleClick}>Click me</Button>)

    fireEvent.click(screen.getByText('Click me'))
    expect(handleClick).toHaveBeenCalledTimes(1)
  })

  it('shows loading state', () => {
    render(<Button loading>Loading</Button>)
    expect(screen.getByText('Loading')).toHaveClass('opacity-50')
  })

  it('applies correct variant classes', () => {
    render(<Button variant="secondary">Secondary</Button>)
    expect(screen.getByText('Secondary')).toHaveClass('bg-secondary')
  })
})

E2E Testing with Playwright¶

// e2e/auth.spec.ts
import { test, expect } from "@playwright/test";

test.describe("Authentication Flow", () => {
  test("user can login successfully", async ({ page }) => {
    await page.goto("/login");

    await page.fill('[data-testid="username"]', "testuser");
    await page.fill('[data-testid="password"]', "testpassword");
    await page.click('[data-testid="login-button"]');

    await expect(page).toHaveURL("/dashboard");
    await expect(page.locator('[data-testid="user-menu"]')).toBeVisible();
  });

  test("shows error for invalid credentials", async ({ page }) => {
    await page.goto("/login");

    await page.fill('[data-testid="username"]', "wronguser");
    await page.fill('[data-testid="password"]', "wrongpassword");
    await page.click('[data-testid="login-button"]');

    await expect(page.locator('[data-testid="error-message"]')).toBeVisible();
    await expect(page.locator('[data-testid="error-message"]')).toContainText(
      "Invalid",
    );
  });

  test("user can logout", async ({ page }) => {
    // Login first
    await page.goto("/login");
    await page.fill('[data-testid="username"]', "testuser");
    await page.fill('[data-testid="password"]', "testpassword");
    await page.click('[data-testid="login-button"]');

    // Then logout
    await page.click('[data-testid="user-menu"]');
    await page.click('[data-testid="logout-button"]');

    await expect(page).toHaveURL("/login");
  });
});

}

Spacing System¶

// Tailwind spacing configuration
module.exports = {
  theme: {
    spacing: {
      xs: "0.5rem", // 8px
      sm: "1rem", // 16px
      md: "1.5rem", // 24px
      lg: "2rem", // 32px
      xl: "3rem", // 48px
      "2xl": "4rem", // 64px
      "3xl": "6rem", // 96px
    },
  },
};

Build System¶

Vite Configuration¶

// vite.config.ts
import { defineConfig } from "vite";
import react from "@vitejs/plugin-react";
import path from "path";

export default defineConfig({
  plugins: [react()],
  resolve: {
    alias: {
      "@": path.resolve(__dirname, "./src"),
    },
  },
  server: {
    port: 3000,
    proxy: {
      "/api": {
        target: "http://localhost:8000",
        changeOrigin: true,
      },
    },
  },
  build: {
    outDir: "dist",
    sourcemap: true,
    rollupOptions: {
      output: {
        manualChunks: {
          vendor: ["react", "react-dom"],
          router: ["react-router-dom"],
          ui: ["@radix-ui/react-dialog", "@radix-ui/react-dropdown-menu"],
        },
      },
    },
  },
  optimizeDeps: {
    include: ["react", "react-dom", "react-router-dom"],
  },
});

Environment Variables¶

# .env.local
VITE_API_URL=http://localhost:8000/api/v1
VITE_APP_NAME=ReViewPoint
VITE_ENVIRONMENT=development

Performance Optimization¶

Code Splitting¶

// Lazy loading for route components
const Dashboard = lazy(() => import('@/pages/Dashboard'))
const Profile = lazy(() => import('@/pages/Profile'))
const Uploads = lazy(() => import('@/pages/Uploads'))

// Usage with Suspense
<Suspense fallback={<LoadingSpinner />}>
  <Dashboard />
</Suspense>

Memoization¶

// Memoizing expensive components
const ExpensiveComponent = memo(({ data }: { data: ComplexData }) => {
  const processedData = useMemo(() => {
    return expensiveDataProcessing(data)
  }, [data])

  return <div>{/* Render processed data */}</div>
})

// Memoizing callback functions
const ParentComponent = () => {
  const [items, setItems] = useState<Item[]>([])

  const handleItemClick = useCallback((id: string) => {
    setItems(prev => prev.map(item =>
      item.id === id ? { ...item, selected: !item.selected } : item
    ))
  }, [])

  return (
    <div>
      {items.map(item => (
        <ItemComponent key={item.id} item={item} onClick={handleItemClick} />
      ))}
    </div>
  )
}

Accessibility¶

ARIA Implementation¶

// Accessible button component
export const Button = forwardRef<HTMLButtonElement, ButtonProps>(
  ({ children, loading, ...props }, ref) => {
    return (
      <button
        ref={ref}
        aria-disabled={loading}
        aria-describedby={loading ? 'loading-text' : undefined}
        {...props}
      >
        {loading && (
          <span id="loading-text" className="sr-only">
            Loading...
          </span>
        )}
        {children}
      </button>
    )
  }
)

// Accessible form field
export const FormField = ({ label, error, children, ...props }) => {
  const id = useId()
  const errorId = `${id}-error`

  return (
    <div>
      <label htmlFor={id}>{label}</label>
      {cloneElement(children, {
        id,
        'aria-invalid': !!error,
        'aria-describedby': error ? errorId : undefined,
        ...props
      })}
      {error && (
        <div id={errorId} role="alert" aria-live="polite">
          {error}
        </div>
      )}
    </div>
  )
}

// Keyboard-accessible dropdown
export const Dropdown = ({ items, onSelect }) => {
  const [isOpen, setIsOpen] = useState(false)
  const [activeIndex, setActiveIndex] = useState(-1)

  const handleKeyDown = (e: KeyboardEvent) => {
    switch (e.key) {
      case 'ArrowDown':
        e.preventDefault()
        setActiveIndex(prev => (prev + 1) % items.length)
        break
      case 'ArrowUp':
        e.preventDefault()
        setActiveIndex(prev => prev <= 0 ? items.length - 1 : prev - 1)
        break
      case 'Enter':
      case ' ':
        e.preventDefault()
        if (activeIndex >= 0) {
          onSelect(items[activeIndex])
          setIsOpen(false)
        }
        break
      case 'Escape':
        setIsOpen(false)
        break
    }
  }

  return (
    <div
      role="combobox"
      aria-expanded={isOpen}
      aria-haspopup="listbox"
      onKeyDown={handleKeyDown}
      tabIndex={0}
    >
      {/* Component implementation */}
    </div>
  )
}

Detailed Module Documentation¶

Explore the comprehensive source code documentation for essential frontend modules:

Bootstrap & Configuration¶

Application Entry Point - React app initialization and providers

Query Client - React Query configuration and cache management
API Base Client - HTTP client with interceptors and error handling
Environment Configuration - Environment variables and settings
Feature Flags - Feature toggle management

State Management¶

Authentication Store - User authentication state with Zustand

Architecture Overview¶

The frontend follows a modular architecture with clear separation of concerns:

src/main.tsx - Application bootstrap with providers and error boundaries
src/App.tsx - Root component with routing and global components
src/lib/ - Core infrastructure including API clients, state management, and configuration
src/components/ - Reusable UI components organized by domain
src/pages/ - Route-level components representing different application screens
src/hooks/ - Custom React hooks for shared logic

For complete module coverage, additional documentation will be added covering:

Component library (UI, layout, domain-specific components)
Custom hooks and utilities
Page components and routing
Testing utilities and mocks

Component Patterns¶

The ReViewPoint frontend follows established React patterns for building reusable and maintainable components:

Container and Presentation Components¶

Container Components: Handle data fetching and state management
Presentation Components: Focus purely on rendering UI based on props
Custom Hooks: Extract reusable logic for cleaner component code

Composition Patterns¶

Higher-Order Components (HOCs): For cross-cutting concerns like authentication
Render Props: For flexible component composition
Context Providers: For sharing state across component trees

Responsive Design¶

The frontend implements a mobile-first responsive design approach:

Breakpoint System¶

Mobile: 320px - 767px (base styles)
Tablet: 768px - 1023px (md breakpoint)
Desktop: 1024px+ (lg breakpoint and up)

Layout Strategies¶

CSS Grid: For complex layout arrangements
Flexbox: For component-level layouts
Tailwind CSS: Utility-first responsive classes
