Frontend library written in Typescript to use in game provider games to communicate with operator displaying your game.

Also used on operator side in order to map events from providers to your system.

Documentation

npm i @valkyrie-fnd/valkyrie-event-adapter

or using yarn

yarn add @valkyrie-fnd/valkyrie-event-adapter

If your're a provider and want to follow Valkyrie events you use ValkyrieWrapper.

In relevant places in your code you need to call ValkyrieWrapper to notify it of events that happen. Eg vm.gameLoaded() when the game's resources are finished loading.

When implemented fully, you can make use of the test site (read below) to verify your events are being sent as expected. Read the docs what functions exist and verify using the test site.

import { ValkyrieWrapper } from '@valkyrie-fnd/valkyrie-event-adapter';
//...
// Get valkyrieReceiver instance
const vw = new ValkyrieWrapper(window.parent, window, valkyrieReceiver);
const unregister = vw.init();

//....
// Call once the game is loaded and has the UI ready to be shown to the player.
// Should not be called while the game is still in process of loading assets etc
vw.gameLoaded();

//...
// If you need to remove any event listeners
unregister();

valkyrieReceiver needs to implement the ValkyrieReceiver interface.

export interface ValkyrieReceiver {
  autoPlay?: (action: AutoPlayAction) => void
  volume?: (muted: boolean) => void
  refreshBalance?: () => void
}

Commands sent by the wrapper of your game should be handled by it.
Eg. when the wrapper send a autoplay command the autoPlay-function on ValkyrieReceiver will be called and your game should handle it.

unregister is a function that will remove event listeners that is added to the second parameter(window).

To verify a game send the correct events and has implemented ValkyrieReceiver interface correctly you can use the test site.

It is available here. To use it, simply paste a url to a game in the input field and validate all events are coming in as expected, as well as validating the game iframe responds to the events sent to it.

The source code for the test site is available here.

Make sure CHANGELOG is updated with relevant changes.

When ready to release then use Prepare release workflow to prepare a release. This will create a PR for you to merge. Upon merge of the PR a github release will be created as well as the package published to NPM.
