A TypeScript library and CLI for capturing Chrome DevTools heap snapshots from Puppeteer-controlled pages and querying them for objects with matching properties. It enables web scraping by extracting data directly from JavaScript heap memory.

Use cases

• scrape data from websites via javascript heap snapshots
• extract instagram post metadata like video view counts
• find objects in a page's heap with specific properties
• fetch and query chrome heap snapshots from the command line
• get data not exposed in the DOM from a webpage

When to choose

• you need data embedded in JavaScript objects that isn't in the DOM or network responses
• you're already using Puppeteer and want to inspect page memory
• you want a CLI to quickly query heap snapshots for URLs

When to avoid

• you need a fast, optimized scraping solution - heap traversal is computationally expensive
• your target data is available via DOM selectors or API responses
• memory-constrained environments - snapshots can grow to 250mb or more
