webview.isClosed()

Checks whether the webview has been closed and is no longer available.

Parameters

None.

Returns

Promise<boolean> - Returns true if the webview is closed, false if it's still open

Description

The isClosed() method allows you to check if a webview instance is still active. This is useful for conditional operations, cleanup logic, and preventing operations on closed webviews.

Example

import {Webview} from '@homunculus/sdk';

const panel = await Webview.open({
    source: 'ui/status-panel.html'
});

// Check if webview is still open
if (!(await panel.isClosed())) {
    console.log('Panel is still open');
    // Safe to perform operations
} else {
    console.log('Panel has been closed');
    // Don't try to use the webview
}
