* __mandatoryInstallMode__ *(codePush.InstallMode)* - Specifies when you would like to install updates which are marked as mandatory. Defaults to `codePush.InstallMode.IMMEDIATE`. Refer to the [`InstallMode`](#installmode) enum reference for a description of the available options and what they do.
* __minimumBackgroundDuration__ *(Number)* - Specifies the minimum number of seconds that the app needs to have been in the background before restarting the app to apply the udpate. This property only applies to updates which are installed using `InstallMode.ON_NEXT_RESUME`, and can be useful for getting your update in front of end users sooner, without being too obtrusive. Defaults to `0`, which has the effect of applying the update immediately after a resume, regardless how long it was in the background.
* __updateDialog__ *(UpdateDialogOptions)* - An "options" object used to determine whether a confirmation dialog should be displayed to the end user when an update is available, and if so, what strings to use. Defaults to `null`, which has the effect of disabling the dialog completely. Setting this to any truthy value will enable the dialog with the default strings, and passing an object to this parameter allows enabling the dialog as well as overriding one or more of the default strings. Before enabling this option within an App Store-distributed app, please refer to [this note](#user-content-apple-note).

###### Methods
- __install(installMode: codePush.InstallMode = codePush.InstallMode.ON_NEXT_RESTART): Promise<void>__: Installs the update by saving it to the location on disk where the runtime expects to find the latest version of the app. The `installMode` parameter controls when the changes are actually presented to the end user. The default value is to wait until the next app restart to display the changes, but you can refer to the [`InstallMode`](#installmode) enum reference for a description of the available options and what they do.
