Main Process in Electron Js

• In Electron.js, the main process is a fundamental concept that governs the behavior and functionality of your desktop application. It is responsible for managing the application's lifecycle, handling system events, creating and managing windows, and performing tasks that require access to native operating system resources.

Here are some key aspects of the main process in Electron.js:

• Entry Point: The main process starts when your Electron application is launched. It typically begins with the execution of a JavaScript file, commonly named `main.js` or specified in the `main` field of your application's package.json file.

• Application Lifecycle: The main process controls the overall lifecycle of your application. It receives events from the operating system, such as when the application is ready, activated (becomes the foreground application), or closed. It allows you to define custom logic to handle these events, manage application state, and perform cleanup tasks.

• BrowserWindow: The main process creates and manages windows using the BrowserWindow module. It can create multiple windows, each representing a separate instance of the renderer process. The main process controls the behavior of windows, including their position, size, and interaction with the operating system.

• Native Capabilities: The main process has access to native operating system capabilities and APIs. It enables you to perform tasks that require system-level operations, such as interacting with the file system, accessing network resources, spawning child processes, and interacting with hardware devices.

• Inter-Process Communication (IPC): The main process serves as a hub for communication between the renderer processes and facilitates data exchange and coordination. It provides IPC mechanisms to send messages, trigger actions, and share data between the main process and renderer processes.

• Modules and APIs: Electron provides various modules and APIs that are available in the main process, allowing you to extend the functionality of your application. These modules include dialog, menu, tray, globalShortcut, autoUpdater, and more. You can use these modules to create custom menus, system notifications, handle user interactions, and perform other tasks.

• Overall, the main process in Electron.js is the backbone of your application. It manages the application's overall functionality, controls windows, handles system events, and provides access to native capabilities. It works in conjunction with the renderer processes to create a cohesive and interactive desktop application.
