``typescript
import { HttpRequest } from "@aws-sdk/protocol-http";
import {
GreetingService as __GreetingService,
SayHelloInput,
SayHelloOutput,
getGreetingServiceHandler,
} from "@greeting-service/service-greeting";
import { convertEvent, convertResponse } from "@aws-smithy/server-apigateway";
import { APIGatewayProxyEventV2, APIGatewayProxyResultV2, APIGatewayProxyHandlerV2 } from "aws-lambda";
class GreetingService implements __GreetingService {
SayHello(input: SayHelloInput, request: HttpRequest): SayHelloOutput {
return {
greeting: Hello ${input.name}! How is ${input.city}?,
};
}
}
const serviceHandler = getGreetingServiceHandler(new GreetingService());
export const lambdaHandler: APIGatewayProxyHandlerV2 = async (
event: APIGatewayProxyEventV2
): Promise => {
console.log(Received event: ${JSON.stringify(event)});

// Convert apigateway's lambda event to an HttpRequest.
const convertedEvent = convertEvent(event);

// Call the service handler, which will route the request to the GreetingService
// implementation and then serialize the response to an HttpResponse.
let rawResponse = await serviceHandler.handle(convertedEvent);

// Convert the HttpResponse to apigateway's expected format.
const convertedResponse = convertResponse(rawResponse);
console.log(Returning response: ${JSON.stringify(convertedResponse)});
return convertedResponse;
};
