Crawlee JavaScript SDK
The Crawlee JavaScript SDK is a Node.js/TypeScript library for building reliable web scrapers and crawlers. It provides a family of crawler classes - BasicCrawler, HttpCrawler, CheerioCrawler, JSDOMCrawler, LinkeDOMCrawler, PuppeteerCrawler, PlaywrightCrawler, and AdaptivePlaywrightCrawler - along with shared infrastructure for AutoscaledPool resource management, proxy rotation, session pooling, RequestQueue task queuing, Dataset result storage, and KeyValueStore unstructured data persistence. Crawlee handles retries, error recovery, request fingerprinting, and statistics tracking out of the box, allowing developers to focus on extraction logic.
