It starts silently. Your Electron application—perhaps a trading terminal, a messaging client, or a monitoring dashboard—launches with a pristine 150MB memory footprint. It feels snappy. Three days later, the user reports sluggish UI interactions. You check the Task Manager: 2.4GB RAM usage. You haven't loaded new data. You haven't cached large images. The culprit is often invisible to casual inspection but deadly to long-running Chromium processes: Detached DOM Trees . This guide covers exactly why these leaks occur in the V8/Blink engine, how they bypass standard garbage collection, and how to implement a rigorous architectural fix using modern TypeScript and WeakReferences. What is a Detached DOM Tree? To solve the leak, you must understand how Chromium’s garbage collector (Mark-and-Sweep) views the DOM. A DOM node is considered "attached" when it is part of the active document tree. It is considered "garbage" when it is removed from the tree and ...
