Reference

constructor

When creating a new instance of the presenter you can pass the following paramters:

interface IConstructorParameters {
	versionChecker: IVersionChecker,
	showInfoMessage: IShowInfoMessage,
	openAppStorePage: IOpenAppStorePage,
	textsConfig?: ITextsConfigParameter
}

versionChecker

The version checker to use, it has to be an instance of AppVersionChecker.

const versionChecker = new AppVersionChecker( { ... } );

const presenter = new CheckAppVersionPresenter( { versionChecker, ... } );

showInfoMessage

An object in charge of showing the required or recommended info messages to the user, it must implement the IShowInfoMessage interface:

interface IShowMessageButton {
	text: string,
	onPress?: () => void
}

interface IShowMessageParameters {
	title: string,
	message: string,
	buttons: IShowMessageButton[]
}

interface IShowInfoMessage {
	showMessage: ( parameters: IShowMessageParameters ) => void;
}

You can use the ShowInfoMessage class included in the package to show the messages using the standard react native's Alert backend.

Example

import { ShowInfoMessage }, CheckAppVersionPresenter from '@amalgamaco/check-app-version-presenter';

const showInfoMessage = new ShowInfoMessage();
const presenter = new CheckAppVersionPresenter( { showInfoMessage, ... } );

openAppStorePage

An object in charge of opening the app's store page when the user chooses to update the app, it must implement the IOpenAppStorePage interface:

interface IOpenAppStorePage {
	openAppStore: () => Promise<boolean>;
}

You can use the OpenAppStorePage class included in the package to open the stores page using react native's Linking backend.

Example

import { OpenAppStorePage }, CheckAppVersionPresenter from '@amalgamaco/check-app-version-presenter';

const openAppStorePage = new OpenAppStorePage( {
	androidStoreURL: 'market://details?id=my-awesome-app',
	iosStoreURL: 'itms-apps://itunes.apple.com/us/app/apple-store/id1111111111'
} );

const presenter = new CheckAppVersionPresenter( { openAppStorePage, ... } );

textsConfig

An object with different texts to show in the recommended to update and required to update popups, it must implement the ITextsConfigParameter interface:

interface IRecommendedToUpdatePopupTextsConfigParameter {
	title?: string,
	message?: string,
	updateButton?: string,
	cancelButton?: string
}

interface IRequiredToUpdatePopupTextsConfigParameter {
	title?: string,
	message?: string,
	updateButton?: string
}

interface ITextsConfigParameter {
	recommendedToUpdatePopup?: IRecommendedToUpdatePopupTextsConfig,
	requiredToUpdatePopup?: IRequiredToUpdatePopupTextsConfig
}

If you don't pass any configuration the default texts will be used:

{
	recommendedToUpdatePopup: {
		title: 'We have new features for you!',
		message: 'You can now download the latest version of the app.',
		updateButton: 'Update',

	},
	requiredToUpdatePopup: {
