Delete Old Cognito Records (Reduce Cost)

	//
	// Run this in Lambda for as long as is required to get through your pool. If you re-run it'll need to skip the keep records,
	// but there should be less the second time around
	//


	import { CognitoIdentityClient, ListIdentitiesCommand, DeleteIdentitiesCommand } from "@aws-sdk/client-cognito-identity";

	// Initialize the Cognito Identity Client
	const client = new CognitoIdentityClient({ region: "<IDENTITY POOL REGION e.g. us-east-1>" });

willblaschko / data.json

Created March 24, 2019 22:53

An example of using nested APL elements (Containers, Pagers) to achieve over 200 items in a relatively small payload. Use sparingly, this starts to have impact on performance of rendering.

	{
	"grid": {
	"values": [
	[ 2, 2, 3, 4, 5, 6, 7, 8, 9, 10 ],
	[ 1, 2, 4, 4, 5, 6, 7, 8, 9, 10 ],
	[ 1, 1, 3, 4, 5, 6, 7, 8, 9, 10 ],
	[ 2, 2, 3, 4, 5, 6, 7, 8, 9, 10 ],
	[ 1, 2, 4, 4, 5, 6, 7, 8, 9, 10 ],

willblaschko / spriteAnimations.js

Created March 23, 2019 22:20

An example of how to create rough APL sprite animations using Pagers and sequential page commands. Your mileage may vary on smoothness of transition based on other commands being executed.

	...

	let spriteCommands = [];
	for (...) {

	...

	spriteCommands.push({
	"type": "SetPage",
	"componentId": "b",

willblaschko / animations.js

Last active March 23, 2019 22:13

A Node.js support function (and example Sequences) that quickly creates all the commands required to animate a multi-item Sequence, including customization to control speed, jump, and whether the animation reverses.

	module.exports = {
	animate: function (componentId, count = 7, delay = 20, jump = 1, reverse = true) {
	let commands = [];

	for (let i = 0; i < count; i += jump) {

	commands.push({
	"type": "ScrollToIndex",
	"componentId": componentId,
	"index": i,

willblaschko / RequestHandler.js

Created March 3, 2019 12:25

Inside the RequestHandler, override the ResponseBuilder to be able to send multiple "speak" requests to concat. This makes it easier to pass between different handlers/functions, each can add a preamble if required (e.g. "Game over..." + "Starting a new game").

	const RequestHandler = {

	process(handlerInput) {
	//log our request
	console.log("REQUEST ENVELOPE = " + JSON.stringify(handlerInput.requestEnvelope));

	//required function taken from Alexa SDK
	function trimOutputSpeech(speechOutput) {
	if (!speechOutput) {
	return '';
