How Alerts Works

Alert Handling in VaahShare

This documentation explains how the application detects user idle time and handles it by showing a dialog and saving alerts. The flow involves the main process, renderer process, and inter-process communication (IPC) using Electron.

Components

1. Main Process (main.ts)

• Listens for the did-finish-load event to start the idle timer.
• Manages the idle timer and handles IPC events to toggle the idle time dialog and save alerts.

2. Renderer Process

• Handles showing and hiding the idle time dialog.
• Communicates with the main process via IPC to toggle the dialog and save alerts.

Flow :

1. Start Idle Timer :

• When the window finishes loading, the startIdleTimer function is called to begin monitoring idle time.

2. Idle Timer Function (startIdleTimer) :

• Sets an interval to check system idle time using powerMonitor.
• If the idle time exceeds a threshold, the interval is cleared, and the renderer process is notified to show the idle time dialog.

3. Renderer Process Idle Time Handling (handleIdleTime) (root.js) :

• Listens for the toggle-idle-time-dialog event to show or hide the idle time dialog.
• If the user is idle, the dialog is shown, and an alert is saved via IPC

4. Idle Time Dialog Close Handler (onIdleTimeDialogClose) :

• Hides the idle time dialog and notifies the main process to resume the idle timer.

5. Main Process IPC Handlers (main.js) :

• Listens for the toggle-idle-time-dialog event to start or stop the idle timer based on the dialog visibility.
• Listens for the save-alert-user-idle event to save an alert indicating the user is idle
