The Problem Space

Modern news consumption faces three critical challenges:

1. Limited Interaction: Traditional news platforms offer a passive, "read-only" experience that fails to engage users effectively.
2. Reading Friction: The requirement for undivided attention during news consumption creates significant barriers:
   • Disrupts daily activities
   • Increases screen time
   • Causes eye strain
   • Limits multitasking capabilities
3. Information Overload: Users struggle with:
   • Overwhelming volume of news sources
   • Difficulty in filtering relevant content
   • Challenges in accessing real-time updates
   • Limited ability to process information efficiently

The Solution

AV News Stream solves these challenges with:

1. Seamless Text-to-Speech Integration

Implemented a sophisticated voice integration system that:

• Utilizes Web Speech API for natural text-to-speech conversion
• Enables hands-free browsing experience
• Reduces screen time and eye strain
• Facilitates multitasking while consuming news

Implementation Example:

const textToSpeech = (text) => {
  const speech = new SpeechSynthesisUtterance();
  speech.text = text;
  speech.rate = 1.0;  // Configurable speech rate
  speech.pitch = 1.0; // Natural pitch
  speech.volume = 1.0;
  window.speechSynthesis.speak(speech);
};

2. Real-Time Updates System

Integrated multiple APIs for comprehensive coverage:

• News API for diverse article sources
• Gnews.io for real-time updates
• YouTube API for live news streaming
• GitHub API for repository tracking
• Notion API for project documentation

Integration Example:

const fetchNewsData = async () => {
    try {
        const [NewsOrgArticles, GNewsArticles] = await Promise.all([
            fetchNewsapiAPI(),
            fetchGNewsAPI()
        ]);
        
        // Merge and deduplicate articles
        const mergedArticles = [...GNewsArticles, ...NewsOrgArticles]
            .filter((article, index, self) => 
                index === self.findIndex((t) => t.title === article.title)
            );
            
        return mergedArticles;
    } catch (error) {
        console.error('Error fetching news:', error);
        throw error;
    }
};

💡 Key Features

1. Voice-Enabled News Reading

The standout feature is voice integration using the Web Speech API. Users can enjoy a hands-free experience, making it easier to stay informed while multitasking.
Here’s how the text-to-speech functionality is implemented:

const textToSpeech = (text) => {
  const speech = new SpeechSynthesisUtterance();
  speech.text = text;
  window.speechSynthesis.speak(speech);
};

2. Article Save Functionality

Powered by Redux Toolkit, users can save their favorite articles for later viewing, ensuring an organized and personalized experience:

const saveSlice = createSlice({
    name: "save",
    initialState: {
        savedArticles: [],
    },
    reducers: {
        addArticle: (state, action) => {
            const isArticleAlreadySaved = state.savedArticles.some(
                article => article.title === action.payload.title
            );
            if (!isArticleAlreadySaved) {
                state.savedArticles.push(action.payload);
            }
        },
        removeArticle: (state, action) => {
            state.savedArticles = state.savedArticles.filter(
                article => article.title !== action.payload.title
            );
        }
    }
});

3. Integration of Multiple APIs

• 📰 News API: Access a diverse range of news articles, including archived content.
• 🌟 Gnews.io: Stay updated with breaking news and trending topics.
• 📹 YouTube API: Stream live news videos for real-time updates.
• 📁 GitHub API: Track changes in repositories.
• 📖 Notion API: Add project descriptions through Notion pages.

4. Advanced Search Functionality

The search feature has been optimized to reduce excessive API calls and enhance efficiency:

const handleSearch = async () => {
    if (searchText) {
        try {
            const queryUrl = `/api/search?query=${encodeURIComponent(searchText)}`;
            const response = await fetch(queryUrl);
            const data = await response.json();
            setNewsCopy(data.articles || []);
        } catch (error) {
            console.error('Error fetching search results:', error);
            setNewsCopy([]);
        }
    }
};

🚧 Technical Challenges & Solutions

1. CORS Implementation

Challenge: NewsAPI.org's free tier limitations in production.
Solution: Implemented a custom Express backend:

import express from 'express';
import cors from 'cors';

const app = express();
app.use(cors());

app.get('/api/news', async (req, res) => {
    const { category } = req.query;
    try {
        let url = `https://newsapi.org/v2/top-headlines?country=${country}&apiKey=${API_KEY}`;
        const response = await fetch(url);
        const data = await response.json();
        res.json(data);
    } catch (error) {
        res.status(500).json({ error: 'Failed to fetch news' });
    }
});

2. Data Quality Management

Challenge: Inconsistent data from multiple APIs.
Solution: Integrated multiple sources with robust validation:

const fetchNewsData = async () => {
    const [NewsOrgArticles, GNewsArticles] = await Promise.all([
        fetchNewsapiAPI(),
        fetchGNewsAPI()
    ]);
    const mergedArticles = [...GNewsArticles, ...NewsOrgArticles];
    return mergedArticles;
};

3. Search Optimization

Challenge: API exhaustion due to frequent calls.
Solution: Search implementation refactored to reduce API hits (as shown above).

4. Null Data Handling

Challenge: Inconsistent data from multiple APIs.

Solution: Implemented robust validation:

const validateArticle = (article) => {
    return {
        ...article,
        title: article?.title || 'Untitled',
        description: article?.description || 'No description available',
        imageUrl: article?.imageUrl || defaultImage,
        author: article?.author || 'Unknown Author'
    };
};

const processArticles = (articles) => {
    return articles
        .filter(article => article.title && article.description)
        .map(validateArticle);
};
