Frontend Service Implementation

// src/services/news.ts
import { createCircuitBreaker } from '@/utils/circuit-breaker';

export interface NewsArticle {
  title: string;
  description: string;
  url: string;
  source: string;
  publishedAt: string;
  image?: string;
}

const newsBreaker = createCircuitBreaker<NewsArticle[]>({
  name: 'News',
  cacheTtlMs: 5 * 60_000, // 5 minutes
});

export async function fetchNews(category = 'general'): Promise<NewsArticle[]> {
  return newsBreaker.execute(async () => {
    const resp = await fetch(`/api/news?category=${category}`);
    if (!resp.ok) throw new Error(`HTTP ${resp.status}`);
    const data = await resp.json();
    return data.articles || [];
  }, []);
}

export async function searchNews(query: string): Promise<NewsArticle[]> {
  const resp = await fetch(`/api/news?q=${encodeURIComponent(query)}`);
  if (!resp.ok) throw new Error(`HTTP ${resp.status}`);
  const data = await resp.json();
  return data.articles || [];
}

HackerNews (No API Key Needed)

For tech news, HackerNews API is free and unlimited:

// Fetch top 30 stories
const topIds = await fetch('https://hacker-news.firebaseio.com/v0/topstories.json').then(r => r.json());
const stories = await Promise.all(
  topIds.slice(0, 30).map((id: number) =>
    fetch(`https://hacker-news.firebaseio.com/v0/item/${id}.json`).then(r => r.json())
  )
);
// Each story: { title, url, score, by, time, descendants }

Panel Rendering Pattern

private render(articles: NewsArticle[]): void {
  const rows = articles.map(a => `
    <div class="news-item">
      <a href="${a.url}" target="_blank" rel="noopener" class="news-title">${escapeHtml(a.title)}</a>
      <div class="news-meta">
        <span class="news-source">${escapeHtml(a.source)}</span>
        <span class="news-time">${formatTime(new Date(a.publishedAt))}</span>
      </div>
    </div>
  `).join('');
  this.setContent(`<div class="news-list">${rows}</div>`);
}

Always escape user-controlled strings with escapeHtml() to prevent XSS.
