Cheerio is a fast, flexible, and elegant library for parsing and manipulating HTML and XML on the server side (Node.js). It provides a jQuery-like API for traversing and manipulating the DOM of parsed documents, designed for web scraping, data extraction, and HTML transformation tasks. The library abstracts away the underlying parser (htmlparser2 for speed, parse5 for standards compliance) via a factory pattern, offering a consistent Cheerio API regardless of parser choice. Key entry points include the main `load` function that converts HTML strings or buffers into a Cheerio instance, static methods like `html`, `xml`, `text`, and `parseHTML`, and utility functions for CSS handling, form serialization, and attribute manipulation. External dependencies include cheerio-select for CSS selector parsing, domutils for core DOM traversal, and optional HTTP fetching via undici for live URL parsing.
The LLM identified 2 files worth highlighting for reuse:
Implements `getParse` factory that accepts an options object and returns a parse function. It handles strings, buffers, and pre-parsed DOM nodes, and delegates to either htmlparser2 or parse5 based on `_useHtmlParser2` option. This abstraction allows Cheerio to support multiple parsers transparently and can be extracted as a reusable parser-switching utility for similar projects.
Exports pure utility functions like `camelCase`, `cssCase`, `domEach`, `isCheerio`, and `isHtml`. These are well-typed, side-effect-free, and demonstrate clean separation of concerns. They are trivial to extract into a standalone library for string manipulation or DOM iteration patterns.
