Blink DOM Tree Architecture and Implementation Deep Dive

This technical deep dive explores the C++ architecture and implementation of the Document Object Model (DOM) within Blink, Chromium’s rendering engine. It details how the DOM is represented as a hierarchical tree of C++ objects, with the Node class serving as the base for more specialized structures like Element, Document, and Text. The text explains the integration of Oilpan, a trace-based garbage collector that unifies memory management between the browser's C++ code and the V8 JavaScript engine. Furthermore, the sources describe the parsing pipeline that constructs the tree from HTML and the specialized mechanisms used to link DOM nodes with layout, styling, and event propagation systems. Key features such as Shadow DOM encapsulation, mutation observation, and the Web IDL binding layer are analyzed to show how they ensure standards compliance and high performance. Ultimately, the overview highlights how Blink optimizes memory footprints and threading constraints to maintain a responsive user interface during complex document manipulations.
