  If you are developing an Electron application involving native C++ modules—such as   better-sqlite3 ,   serialport , or your own custom Node addons—you have almost certainly encountered this compile-time ABI mismatch: Error: The module '/path/to/project/node_modules/better-sqlite3/build/Release/better_sqlite3.node' was compiled against a different Node.js version using NODE_MODULE_VERSION 115. This version of Node.js requires NODE_MODULE_VERSION 121. Please try re-compiling or re-installing the module (for instance, using `npm rebuild` or `npm install`). The generic advice to "delete  node_modules  and run  npm install " rarely works here. This error persists because of a fundamental architectural divergence between your system's Node.js runtime and Electron's bundled runtime. Root Cause Analysis: The ABI Divergence Node.js and Electron both rely on the V8 JavaScript engine. However, they rarely share the exact same version of V8 at any given release poin...

  You have built a robust Electron application. Logic is sound, the architecture is modular, and the UI is modern. But the moment you attempt to load a large dataset—say, a 50MB JSON file containing logs or analytical data—the application freezes. The CSS animations halt, the loading spinner sticks, and the window becomes unresponsive for a noticeable 500ms to 2 seconds. This is the classic "IPC Jank." It is not a React issue; it is a serialization bottleneck. This post details exactly why this happens and provides a production-ready implementation to offload serialization, keeping your Renderer at 60fps. The Why: The Hidden Cost of IPC When you transmit data between the Main process and the Renderer process in Electron using  ipcMain.handle  and  ipcRenderer.invoke , you are crossing a process boundary. Under the hood, Electron uses the  Structured Clone Algorithm  to serialize JavaScript objects into a format suitable for IPC transmission (often via named...
