# Install the official SubScraper SDK
npm install @subscraper/sdk

const client = new SubScraperClient({ apiKey: process.env.SUBSCRAPER_API_KEY! });
const feed = await client.getCommunityPosts({ subreddit: 'typescript', limit: 10 });

console.log(`Fetched ${feed.items?.length} posts from r/${feed.subreddit}`);

// 1. Fetch real-time new submissions from r/node
const newPosts = await client.getCommunityPosts({
  subreddit: 'node',
  sort: 'new',
  limit: 25,
});

// 2. Fetch early breakout posts before they hit hot
const risingPosts = await client.getCommunityPosts({
  subreddit: 'webdev',
  sort: 'rising',
  limit: 15,
});

// Fetch top 50 posts of the past month from r/typescript
const monthlyTop = await client.getCommunityPosts({
  subreddit: 'typescript',
  sort: 'top',
  time: 'month',
  limit: 50,
