Description

Since the migration of HTTP API into the new aws-apigatewayv2 module, it is unclear to me how to use the module to set up a private integration via VPCLink with an alb/nlb using the new aws-apigatewayv2 module when adding routes to the api.
The example shown in Issue 8066 doesn't fit the new library.

import * as apiv2 from '@aws-cdk/aws-apigatewayv2';
import * as apigw from '@aws-cdk/aws-apigateway';


const api = new apiv2.HttpApi(this, "testingApi", {
      apiName: "testingApi",
})

// declare API routes integrations
const link = new apigw.VpcLink(this, 'link', {
  targets: [nlb]
});
const integration = new apigw.HttpIntegration("",{
  httpMethod: apiv2.HttpMethod.ANY,
  options: {
    connectionType: apigw.ConnectionType.VPC_LINK,
    vpcLink: link
  },
  proxy: false
})

api.addRoutes({
  integration: integration,
  methods: [apiv2.HttpMethod.GET, apiv2.HttpMethod.DELETE, apiv2.HttpMethod.POST, apiv2.HttpMethod.OPTIONS, apiv2.HttpMethod.PUT],
  path: "/somePath"
})

// -> throws ...Type 'HttpIntegration' is not assignable to type 'IHttpRouteIntegration'... error

The addRoutes() call requires type 'IHttpRouteIntegration', but I can't figure out how to use the HTTP Proxy Integration to set up a private integration for an alb/nlb linked to routes.

Proposed Solution

A simple code example with just one stack containing the new HTTP API and a linked alb/nlb via private integration using the
aws-apigatewayv2 would be perfect :)

Environment

• CDK CLI Version: 1.61.0
• OS: all
• Language: TypeScript

Other information

We don't have support for vpc link in the aws-apigatewayv2 module.

I've opened an issue to track this - aws/aws-cdk#10119. Examples will be available once this feature has been implemented.
