ADD THE TABLE VIEWER TO YOUR APP

Add a table viewer to your stack

Add the following hightlighted lines to lib/cdk-workshop-stack.ts to add a TableViewer construct to your stack:

import * as cdk from 'aws-cdk-lib';
import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as apigw from 'aws-cdk-lib/aws-apigateway';
import { HitCounter } from './hitcounter';
import { TableViewer } from 'cdk-dynamo-table-viewer';

export class CdkWorkshopStack extends cdk.Stack {
  constructor(scope: cdk.App, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    const hello = new lambda.Function(this, 'HelloHandler', {
      runtime: lambda.Runtime.NODEJS_14_X,
      code: lambda.Code.fromAsset('lambda'),
      handler: 'hello.handler'
    });

    const helloWithCounter = new HitCounter(this, 'HelloHitCounter', {
      downstream: hello
    });

    // defines an API Gateway REST API resource backed by our "hello" function.
    new apigw.LambdaRestApi(this, 'Endpoint', {
      handler: helloWithCounter.handler
    });

    new TableViewer(this, 'ViewHitCounter', {
      title: 'Hello Hits',
      table: //??????
    });
  }
}

What about the table?

As you’ll notice, TableViewer requires that you specify a table property.

What we want is to somehow access the DynamoDB table behind our hit counter. However, the current API of our hit counter doesn’t expose the table as a public member.
