Is there a way to connect a new AWS ApiGateway to existing lambda funtion using AWS-CDK? (TypeScript)

Question

I am new to AWS CDK. I am trying to create a API gateway, and connect it to the AWS lambda. But I want these 2 modules to be separate code structures.

I created the lambda functions and the API gateway in 2 different projects. And my AWS console has both API and lambda init. But I am not sure how to connect my API gateway to these lambdas.

The only way I could find was

    new lambda.Function(this, 'createPr', {
      code: lambda.Code.asset("resources/lambdas"),
      ....
      ....
    });

But this required the directory structure pointing towards lambda code.

Any help would be much appreciated!

You can import the other lambda function from ARN

const otherFunction = lambda.Function.fromFunctionArn(this, 'otherfunction', cdk.Fn.importValue("otherstack-function-arn"))

The cdk.Fn.importValue allow you to import value from other cloudformation script
