Use Cases

Engagement Analysis

Calculate engagement rate for specific posts:

const postInfo = await getPostInfo(url);

const engagementRate = (
  (postInfo.likes + postInfo.comments) / postInfo.author.followers
) * 100;

console.log(`Engagement rate: ${engagementRate.toFixed(2)}%`);

Track Viral Content

Monitor post performance over time:

async function trackPost(url) {
  const info = await getPostInfo(url);
  
  await saveSnapshot({
    postId: info.id,
    likes: info.likes,
    comments: info.comments,
    views: info.views,
    timestamp: new Date()
  });
}

// Track every hour
setInterval(() => trackPost(targetUrl), 60 * 60 * 1000);

Extract Media for Archival

Download post images/videos:

const postInfo = await getPostInfo(url);

for (const media of postInfo.media) {
  const response = await fetch(media.url);
  const buffer = await response.arrayBuffer();
  
  const extension = media.type === 'video' ? 'mp4' : 'jpg';
  await fs.writeFile(`post_${postInfo.shortcode}_${index}.${extension}`, Buffer.from(buffer));
}

Carousel Analysis

Analyze multi-image posts:

const postInfo = await getPostInfo(url);

if (postInfo.type === 'carousel') {
  console.log(`This carousel has ${postInfo.media.length} slides`);
  
  const imageCount = postInfo.media.filter(m => m.type === 'image').length;
  const videoCount = postInfo.media.filter(m => m.type === 'video').length;
  
  console.log(`${imageCount} images, ${videoCount} videos`);
}

What's the difference between views and plays for Reels?

Views typically count unique viewers, while plays count total playbacks (including repeats).

Can I get data from private account posts?

No, only publicly accessible posts can be scraped. Private accounts restrict access.
