Specifies the destination directory to build the app to, defaults to the current working directory.
#### Help
```
-h, --help
```
Prints the usage information.
#### Version
```
-V, --version
```
Prints the version of your `nativefier` install.
#### [name]
```
-n, --name <value>
```
The name of the application, which will affect strings in titles and the icon.
**For Linux Users:** Do not put spaces if you define the app name yourself with `--name`, as this will cause problems (tested on Ubuntu 14.04) when pinning a packaged app to the launcher.
Automatically determined based on the current OS. Can be overwritten by specifying either `linux`, `windows`, `osx` or `mas` for a Mac App Store specific build.
The human-readable copyright line for the app. Maps to the `LegalCopyright` metadata property on Windows, and `NSHumanReadableCopyright` on OS X.
#### [app-version]
```
--app-version <value>
```
The release version of the application. By default the `version` property in the `package.json` is used but it can be overridden with this argument. If neither are provided, the version of Electron will be used. Maps to the `ProductVersion` metadata property on Windows, and `CFBundleShortVersionString` on OS X.
#### [build-version]
```
--build-version <value>
```
The build version of the application. Maps to the `FileVersion` metadata property on Windows, and `CFBundleVersion` on OS X.
Electron version without the `v`, see https://github.com/atom/electron/releases.
#### [no-overwrite]
```
--no-overwrite
```
Specifies if the destination directory should be not overwritten, defaults to false.
#### [conceal]
```
-c, --conceal
```
Specifies if the source code within the nativefied app should be packaged into an archive, defaults to false, [read more](http://electron.atom.io/docs/v0.36.0/tutorial/application-packaging/).
#### [icon]
```
-i, --icon <path>
```
##### Packaging for Windows and Linux
The icon parameter should be a path to a `.png` file.
If you have the optional dependencies `iconutil`, Imagemagick `convert`, and Imagemagick `identify` in your `PATH`, Nativefier will automatically convert the `.png` to a `.icns` for you.
[iConvertIcons](https://iconverticons.com/online/) can be used to convert `.pngs`, though it can be quite cumbersome.
To retrieve the `.icns` file from the downloaded file, extract it first and press File > Get Info. Then select the icon in the top left corner of the info window and press `⌘-C`. Open Preview and press File > New from clipboard and save the `.icns` file. It took me a while to figure out how to do that and question why a `.icns` file was not simply provided in the downloaded archive.
#### [counter]
```
--counter
```
Use a counter that persists even with window focus for the application badge for sites that use an "(X)" format counter in the page title (i.e. Gmail). Same limitations as the badge option (above).
By default, Nativefier uses a preset user agent string for your OS and masquerades as a regular Google Chrome browser, so that sites like WhatsApp Web will not say that the current browser is unsupported.
If this flag is passed, it will not override the user agent.
#### [ignore-certificate]
```
--ignore-certificate
```
Forces the packaged app to ignore certificate errors.
Forces the packaged app to ignore web security errors, such as [Mixed Content](https://developer.mozilla.org/en-US/docs/Security/Mixed_content) errors when receiving HTTP content on a HTTPS site.
Regular expression of URLs to consider "internal"; all other URLs will be opened in an external browser. Defaults to URLs on same second-level domain as app.
If `--flash` is specified, Nativefier will automatically try to determine the location of your Google Chrome flash binary. Take note that the version of Chrome on your computer should be the same as the version used by the version of Electron for the Nativefied package.
Take note that if this flag is specified, the `--insecure` flag will be added automatically, to prevent the Mixed Content errors on sites such as [Twitch.tv](https://www.twitch.tv/).
You can also specify the path to the Chrome flash plugin directly with this flag. The path can be found at [chrome://plugins](chrome://plugins), under `Adobe Flash Player` > `Location`. This flag automatically enables the `--flash` flag as well.
(macOS only) Sets the style for the app's title bar. See more details at electron's [Frameless Window](https://github.com/electron/electron/blob/master/docs/api/frameless-window.md#alternatives-on-macos) documentation.
Consider injecting a custom CSS (via `--inject`) for better integration. Specifically, the CSS should specify a draggable region. For instance, if the target website has a `<header>` element, you can make it draggable like so.
```css
/* site.css */
/* header is draggable... */
header {
-webkit-app-region: drag;
}
/* but any buttons inside the header shouldn't be draggable */
header button {
-webkit-app-region: no-drag;
}
/* perhaps move some items out of way for the traffic light */
a JSON string of key/value pairs to be set as file download options. See [electron-dl](https://github.com/sindresorhus/electron-dl) for available options.
