Usage

Only one function is exported as default. Please see TypeScript type definition.
The function can be called from both main process and renderer process.

`typescript
export default function openAboutWindow(info: {
icon_path: string;
product_name?: string;
package_json_dir?: string;
about_page_dir?: string;
bug_report_url?: string;
bug_link_text?: string;
copyright?: string;
homepage?: string;
description?: string;
license?: string;
css_path?: string | string[];
adjust_window_size?: boolean;
win_options?: BrowserWindowOptions;
use_version_info?: boolean | [string, string][];
show_close_button?: string;
app?: Electron.App;
BrowserWindow?: typeof Electron.BrowserWindow;
ipcMain?: Electron.IpcMain;
}): BrowserWindow
`

Only icon_path property is required, others are optional.
I recommend to specify as below to extract information from package.json as much as possible.
Path to package.json is also automatically detected if possible.

`typescript
openAboutWindow({
icon_path: 'path/to/icon.png'
});
`

If string value is passed to the first parameter, it is passed to icon_path. So following is a shorthand of above code:

`typescript
openAboutWindow('path/to/icon.png');
`

You can check an example app to know how to use this package.

`sh
$ git clone https://github.com/rhysd/about-window.git
$ cd about-window/example
$ npm install
$ npm start

Or for debug


$ npm run debug
`

Since openAboutWindow() depends on several APIs only available on main process, they must be provided by caller when it is called on non-main process.

To mimic the APIs, use @electron/remote module.

`typescript
import {app, BrowserWindow, ipcMain} from '@electron/remote';

openAboutWindow({
icon_path: 'path/to/icon.png'
app,
BrowserWindow,
ipcMain,
});
