Electron applications function using a dual-layer architecture consisting of a main process and multiple renderer processes, with communication between these layers facilitated by interprocess communication (IPC). The main process acts as the entry point and handles system-level tasks, while the renderer processes manage the UI. Tasks such as gathering system information require the renderer to send requests to the main process, which executes commands and sends back results, akin to an asynchronous request-response pattern. TypeScript can be used to organize this communication into clean, modular components, with dedicated classes for specific channels. This setup is demonstrated through a simple example of an Electron app that retrieves and displays the system's kernel version. The app's architecture includes a Main class to initialize and manage the app, a SystemInfoChannel class to handle system info requests, and an IpcService class to facilitate communication between the renderer and main processes. The process is encapsulated in TypeScript, leveraging promises for asynchronous operations, and structured so channels are neatly registered and handled, ensuring a clean, maintainable codebase.
