To build a Reddit and Hacker News trending topics dashboard with time-based filtering (today, 7 days, month) and trend graphs, we can create a React-based dashboard using:

• APIs: Reddit (/r/all, /r/popular) and Hacker News (Firebase API).
• Charts: Recharts for trend visualization.
• UI: Tailwind CSS for styling, shadcn/ui for components.

---

Dashboard Features

1. Time Filters: Today, 7 days, 1 month.
2. Trending Topics: Fetched from Reddit and Hacker News.
3. Updates per Topic: Show posts/updates under each topic.
4. Trend Graph: Line/bar chart for topic popularity over time.

Implementation Plan

1. API Integration:

   • Reddit: Use https://www.reddit.com/r/all.json (or /r/popular.json) with t (time) parameter.
   • Hacker News: Use https://hacker-news.firebaseio.com/v0/topstories.json and fetch item details.

2. Data Processing:

   • Aggregate posts by topic, count mentions, and track trends over time.

3. UI Components:

   • Time filter dropdown.
   • Topic cards with updates.
   • Trend graph (Recharts).
