Create an AWS CDK Stack From the Command Line

This course is written using version 1 of the cdk, while at the time of writting this comment, we are on version 2. If you get stuck, you can refer to this modified code: import * as cdk from 'aws-cdk-lib'; import * as lambda from 'aws-cdk-lib/aws-lambda'; import { Construct } from 'constructs'; import * as appsync from '@aws-cdk/aws-appsync-alpha';

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

// The code that defines your stack goes here

// Create the AppSync GraphQL API
const api = new appsync.GraphqlApi(this, "MyApi", {
  name: "my-book-api",
  schema: appsync.SchemaFile.fromAsset("graphql/schema.graphql"),
  authorizationConfig: {
    defaultAuthorization: {
      authorizationType: appsync.AuthorizationType.API_KEY,
      apiKeyConfig: {
        name: "MyApiKey",
        expires: cdk.Expiration.after(cdk.Duration.days(365)),
      },
    },
  },
});

const listBooksLamdba = new lambda.Function(this, "ListBooksHandler", {
  code: lambda.Code.fromAsset("functions"),
  runtime: lambda.Runtime.NODEJS_14_X,
  handler: "listBooks.handler",
});

const listBooksDataSource = api.addLambdaDataSource(
  "listBooksDataSource",
  listBooksLamdba,
);

listBooksDataSource.createResolver("ListBooksResolver", {
  typeName: "Query",
  fieldName: "listBooks",
});

} }
