Serving S3 from an ApiGatewayV2

Question

Using CDK, I went to try to add an AwsIntegration (to s3) to an apigatewayv2.HttpApi, when I realized that's not possible, and I was mixing up the old API gateway with the new one, which you can't do.

Is my main option here to make a lambda that does the proxying on my behalf?

Accepted Answer

You have 3 main options:

1. Use REST API (v1) which has direct integration with S3. Note that API Gateway has a 10 MB payload size limit.
2. Use a Lambda function to proxy the request to S3. Note that Lambda has a 6 MB payload size limit.
3. I think the preferred option, generate a [pre-signed URL](https://docs.aws.amazon.com/AmazonS3/latest/userguide/ShareObjectPreSignedURL.html) for the S3 object and download it directly from S3 to the client.
