• src/index.ts:14-22 (helper)

  Fetches and parses the RSS feed from The Verge, returns the items array. Used by the handler to get all news.

  async function fetchVergeNews() {
    try {
      const feed = await parser.parseURL(VERGE_RSS_URL);
      return feed.items;
    } catch (error) {
      console.error("Error fetching RSS feed:", error);
      throw new Error("Failed to fetch news from The Verge");
    }
  }

• src/index.ts:38-47 (helper)

  Filters RSS items to those published within the last 'daysBack' days. Called with 1 for daily news.

  function filterNewsByDate(items: Parser.Item[], daysBack: number) {
    const now = new Date();
    const cutoffDate = new Date(now.setDate(now.getDate() - daysBack));
    
    return items.filter((item) => {
      if (!item.pubDate) return false;
      const pubDate = new Date(item.pubDate);
      return pubDate >= cutoffDate;
    });
  }

• src/index.ts:80-98 (helper)

  Formats formatted news items into brief text summaries with title, link, and truncated content (limit 150 chars), up to 'limit' items. Used with 10.

  function formatNewsAsBriefSummary(items: ReturnType<typeof formatNewsItems>, limit: number = 10) {
    if (items.length === 0) {
      return "No news articles found for the specified time period.";
    }
    
    // Limit the number of items
    const limitedItems = items.slice(0, limit);
    
    return limitedItems.map((item, index) => {
      // Extract a brief summary (first 150 characters)
      const summary = item.content.substring(0, 150).trim() + (item.content.length > 150 ? "..." : "");
      
      return `
  ${index + 1}. ${item.title}
     Link: ${item.link}
     Summary: ${summary}
     `;
    }).join("\n---\n");
  }
