Automatically update your catalogs and skill

Tutorial Header

What You Will Need

What this code sample will do

This code sample will update your catalogs and skill with the use of ASK NodeJS SDK. Developers will need to provide their own client id, client secret, and refresh token.

Instructions

  1. Obtain LWA client ID and client secret.
  2. Generate refresh token using ask cli. (You can specify alexa::ask:skills:readwrite with --scopes or not use --scopes.)
  3. Input obtained ids and token to index.js.
  4. Replace sample catalogId and URL with your values. You can update more than one catalog.
  5. Input skill id to update in index.js
  6. Run node index.js from package root to update catalog and skill.
  7. Follow steps below to run update periodically

Running script in AWS lambda

  1. Set up your CDK project
npm install -g aws-cdk
cdk init app --language=typescript
  1. Install AWS SDK if not already installed
npm install aws-sdk
  1. Add the necessary imports in lib/{AnyStackName}.ts:
import * as cdk from 'aws-cdk-lib';
import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as events from 'aws-cdk-lib/aws-events';
import * as targets from 'aws-cdk-lib/aws-events-targets';
  1. Create the AWS Lambda function and configuration to run on schedule using AWS Event Bridge. Modify the cron function to configure how often to update
export class YourStackNameStack extends cdk.Stack {
  constructor(scope: cdk.Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    // Define the Lambda function
    const lambdaFunction = new lambda.Function(this, 'YourLambdaFunction', {
      runtime: lambda.Runtime.NODEJS_14_X,
      handler: 'index.handler',
      code: lambda.Code.fromAsset("PATH_TO_ASK_AUTOMATIC_CATALOG_UPDATE_FUNCTION"),
    });

    // Create an EventBridge rule to trigger the Lambda function every hour
    const rule = new events.Rule(this, 'YourRule', {
      schedule: events.Schedule.cron({ hour: '0' }),
    });

    // Add the Lambda function as the target of the EventBridge rule
    rule.addTarget(new targets.LambdaFunction(lambdaFunction));
  }
}
  1. Build project using npm run build
  2. Deploy stack using cdk deploy

Note: This can be done without AWS CDK. Simply zip up node package and configure AWS lambda/Eventbrige via AWS console

(Optional) To submit skill for certification after skill update.

Modify the runInteractionModelUpdateWorkflow function in index.js to the following to submit skill for instant publish.

Note: Skill will not instant publish if there are changes other than catalog values.

  async function runInteractionModelUpdateWorkflow() {
    try {
      await createDirectories();
      await createInteractionModelCatalogVersion();
      await getSkillPackageAndUpdateCatalogVersion();
      await submitSkillForCertification(); 
    } catch (error) {
      console.error('Error when running update workflow', error);
      throw new Error('Workflow failed', {cause: error});
    }
  }
