# Story 1.4: Basic Web Interface
## Status
Done
## Story
**As a** user
**I want** a clean, responsive web interface to submit YouTube URLs and view extraction progress
**so that** I can easily interact with the transcript extraction system
## Acceptance Criteria
1. Responsive web interface works on desktop, tablet, and mobile devices
2. URL input form with real-time validation and user-friendly error messages
3. Progress indicators show extraction status (validating → extracting → completed)
4. Extracted transcripts display in readable format with metadata
5. Error states handled gracefully with actionable recovery suggestions
6. Interface follows modern UI/UX best practices with shadcn/ui components
## Tasks / Subtasks
- [x] **Task 1: Project Foundation & Layout** (AC: 1, 6)
- [x] Set up React 18 + TypeScript + Vite development environment
- [x] Install and configure shadcn/ui component library
- [x] Create responsive layout structure with header, main content, and footer
- [x] Implement mobile-first responsive design system
- [x] **Task 2: URL Submission Form** (AC: 2, 5)
- [x] Create `SummarizeForm` component with URL input and submit functionality
- [x] Integrate `useURLValidation` hook for real-time URL validation
- [x] Add visual validation indicators (checkmarks, error states)
- [x] Implement form submission with loading states and error handling
- [x] **Task 3: Progress Tracking Interface** (AC: 3)
- [x] Create `ProgressTracker` component with multi-stage progress display
- [x] Implement progress states: validating → extracting → processing → complete
- [ ] Add estimated time remaining and cancellation functionality
- [ ] Create WebSocket integration for real-time progress updates
- [x] **Task 4: Transcript Display** (AC: 4)

### Custom Hooks Implementation
[Source: docs/architecture.md#react-patterns]
**URL Validation Hook**:
```typescript
// src/hooks/useURLValidation.ts
import { useState, useCallback } from 'react';
import { apiClient } from '@/services/apiClient';
interface URLValidationState {
isValid: boolean;
isValidating: boolean;
error?: {
code: string;
message: string;
supportedFormats: string[];
};
}
export function useURLValidation() {
const [validationState, setValidationState] = useState<URLValidationState>({
isValid: false,
isValidating: false,
});
const validateURL = useCallback(async (url: string) => {
if (!url.trim()) {
setValidationState({ isValid: false, isValidating: false });
return;
}
setValidationState({ isValid: false, isValidating: true });
// Client-side validation first
const youtubePatterns = [
/^https?:\/\/(www\.)?(youtube\.com\/watch\?v=|youtu\.be\/|youtube\.com\/embed\/)/,
];
const hasValidPattern = youtubePatterns.some(pattern => pattern.test(url));
if (!hasValidPattern) {
setValidationState({
isValid: false,
isValidating: false,
error: {
code: 'INVALID_URL',
message: 'Invalid YouTube URL format',
supportedFormats: [
'https://youtube.com/watch?v=VIDEO_ID',
'https://youtu.be/VIDEO_ID',
'https://youtube.com/embed/VIDEO_ID'
]
}
});
return;
}
// Server-side validation for security
try {
const response = await apiClient.validateURL(url);
setValidationState({
isValid: response.is_valid,
isValidating: false,
error: response.error ? {
code: response.error.code,
message: response.error.message,
supportedFormats: response.error.details?.supported_formats || []
} : undefined
});
} catch (error) {
setValidationState({
isValid: false,
isValidating: false,
error: {
code: 'VALIDATION_ERROR',
message: 'Failed to validate URL',
supportedFormats: []
}
});
}
}, []);
return { validateURL, validationState };
}
```
**Transcript Extraction Hook**:
```typescript
// src/hooks/useTranscriptExtraction.ts
import { useState, useCallback } from 'react';
import { useMutation } from '@tanstack/react-query';
import { apiClient } from '@/services/apiClient';
import { useWebSocket } from './useWebSocket';
interface ProgressState {
currentStep: string;
percentage: number;
estimatedTimeRemaining?: number;
steps: Array<{
id: string;
label: string;
status: 'pending' | 'in-progress' | 'completed' | 'failed';
}>;
}
export function useTranscriptExtraction() {
const [progress, setProgress] = useState<ProgressState>({
currentStep: 'Preparing...',
percentage: 0,
steps: [
{ id: 'validate', label: 'Validating URL', status: 'pending' },
{ id: 'extract', label: 'Extracting Transcript', status: 'pending' },
{ id: 'process', label: 'Processing Content', status: 'pending' },
{ id: 'complete', label: 'Complete', status: 'pending' }
]
});
const { connect, disconnect } = useWebSocket({
onProgress: (update) => {
setProgress(prev => ({
...prev,
currentStep: update.current_step,
percentage: update.progress_percentage,
estimatedTimeRemaining: update.estimated_time_remaining,
steps: prev.steps.map(step =>
step.id === update.step_id
? { ...step, status: update.status }
: step
)
}));
}
});
const mutation = useMutation({
mutationFn: async (videoId: string) => {
// Start WebSocket connection for progress updates
connect(videoId);
// Start extraction
const response = await apiClient.extractTranscript(videoId);
return response;
},
onSuccess: (data) => {
setProgress(prev => ({
...prev,
currentStep: 'Complete',
percentage: 100,
steps: prev.steps.map(step => ({ ...step, status: 'completed' }))
}));
disconnect();
},
onError: (error) => {
setProgress(prev => ({
...prev,
currentStep: 'Failed',
steps: prev.steps.map(step =>
step.status === 'in-progress'
? { ...step, status: 'failed' }
: step
)
}));
disconnect();
}
});
return {
extractTranscript: mutation.mutateAsync,
progress,
transcript: mutation.data?.transcript,
metadata: mutation.data?.metadata,
isLoading: mutation.isPending,
error: mutation.error
};
}
```
### API Client Implementation
[Source: docs/architecture.md#api-integration]
```typescript
// src/services/apiClient.ts
import axios, { AxiosInstance, AxiosError } from 'axios';
class APIClient {
private client: AxiosInstance;
constructor(baseURL: string = '/api') {
this.client = axios.create({
baseURL,
timeout: 30000,
headers: {
'Content-Type': 'application/json',
},
});
this.setupInterceptors();
}
private setupInterceptors() {
// Request interceptor
this.client.interceptors.request.use((config) => {
console.log(`API Request: ${config.method?.toUpperCase()} ${config.url}`);
return config;
});
// Response interceptor
this.client.interceptors.response.use(
(response) => response,
(error: AxiosError) => {
console.error('API Error:', error.response?.data || error.message);
return Promise.reject(error);
}
);
}
async validateURL(url: string) {
const response = await this.client.post('/validate-url', { url });
return response.data;
}
async extractTranscript(videoId: string, options: any = {}) {
const response = await this.client.post('/transcripts/extract', {
video_id: videoId,
...options
});
return response.data;
}
async getTranscript(videoId: string) {
const response = await this.client.get(`/transcripts/${videoId}`);
return response.data;
}
async getExtractionStatus(jobId: string) {
const response = await this.client.get(`/transcripts/jobs/${jobId}`);
return response.data;
}
}
export const apiClient = new APIClient();
```

### Performance Optimization
- **Code Splitting**: Lazy load components for better initial load performance
- **Bundle Optimization**: Tree shaking and module bundling with Vite
- **API Caching**: React Query for intelligent server state caching
- **Optimistic UI**: Show immediate feedback for user actions
- **WebSocket Efficiency**: Connection pooling and automatic reconnection
### Accessibility Features
- **Keyboard Navigation**: Full keyboard accessibility for all interactive elements
- **Screen Reader Support**: Proper ARIA labels and semantic HTML
- **Color Contrast**: WCAG 2.1 AA compliant color schemes
- **Focus Management**: Visible focus indicators and logical tab order
- **Alternative Text**: Descriptive text for all visual elements
### Security Considerations
- **XSS Prevention**: Input sanitization and Content Security Policy
- **CSRF Protection**: CSRF tokens for state-changing operations
- **HTTPS Only**: Enforce secure connections in production
- **Content Validation**: Client and server-side input validation
- **Error Information**: Avoid exposing sensitive error details
