@aws-cdk/aws-s3objectlambda-alpha

AWS::S3ObjectLambda Construct Library

Version 2.273.0-alpha.0

Separate package

@aws-cdk/aws-s3objectlambda-alpha is not part of aws-cdk-lib — install it separately:

npm install @aws-cdk/aws-s3objectlambda-alpha
pip install aws-cdk.aws-s3objectlambda-alpha

This module is experimental (alpha): its API may change in any release, without a major version bump.

---

The APIs of higher level constructs in this module are experimental and under active development. They are subject to non-backward compatible changes or removal in any future version. These are not subject to the Semantic Versioning model and breaking changes will be announced in the release notes. This means that while you may use them, you may need to update your source code when upgrading to a newer version of this package.

---

This construct library allows you to define S3 object lambda access points.

Handling range and part number requests

Lambdas are currently limited to only transforming GetObject requests. However, they can additionally support GetObject-Range and GetObject-PartNumber requests, which needs to be specified in the access point configuration:

import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as s3 from 'aws-cdk-lib/aws-s3';
import * as s3objectlambda from '@aws-cdk/aws-s3objectlambda-alpha';
import * as cdk from 'aws-cdk-lib';

const stack = new cdk.Stack();
const bucket = new s3.Bucket(stack, 'MyBucket');
const handler = new lambda.Function(stack, 'MyFunction', {
	runtime: lambda.Runtime.NODEJS_LATEST,
	handler: 'index.handler',
	code: lambda.Code.fromAsset('lambda.zip'),
});
new s3objectlambda.AccessPoint(stack, 'MyObjectLambda', {
	bucket,
	handler,
	accessPointName: 'my-access-point',
	supportsGetObjectRange: true,
	supportsGetObjectPartNumber: true,
});

Pass additional data to Lambda function

You can specify an additional object that provides supplemental data to the Lambda function used to transform objects. The data is delivered as a JSON payload to the Lambda:

import * as lambda from 'aws-cdk-lib/aws-lambda';
import * as s3 from 'aws-cdk-lib/aws-s3';
import * as s3objectlambda from '@aws-cdk/aws-s3objectlambda-alpha';
import * as cdk from 'aws-cdk-lib';

const stack = new cdk.Stack();
const bucket = new s3.Bucket(stack, 'MyBucket');
const handler = new lambda.Function(stack, 'MyFunction', {
	runtime: lambda.Runtime.NODEJS_LATEST,
	handler: 'index.handler',
	code: lambda.Code.fromAsset('lambda.zip'),
});
new s3objectlambda.AccessPoint(stack, 'MyObjectLambda', {
	bucket,
	handler,
	accessPointName: 'my-access-point',
	payload: {
		prop: "value",
	},
});

bucket = s3.Bucket(stack, "MyBucket")
handler = lambda_.Function(stack, "MyFunction",
    runtime=lambda_.Runtime.NODEJS_LATEST,
    handler="index.handler",
    code=lambda_.Code.from_asset("lambda.zip")
)
s3objectlambda.AccessPoint(stack, "MyObjectLambda",
    bucket=bucket,
    handler=handler,
    access_point_name="my-access-point",
    payload={
        "prop": "value"
    }

        .code(Code.fromAsset("lambda.zip"))

	Handler: Handler,
	AccessPointName: jsii.String("my-access-point"),
	Payload: map[string]interface{}{
		"prop": jsii.String("value"),
	},
})

Accessing the S3 AccessPoint ARN

If you need access to the s3 accesspoint, you can get its ARN like so:

import * as s3objectlambda from '@aws-cdk/aws-s3objectlambda-alpha';

declare const accessPoint: s3objectlambda.AccessPoint;
const s3AccessPointArn = accessPoint.s3AccessPointArn;

import aws_cdk.aws_s3objectlambda_alpha as s3objectlambda

# access_point: s3objectlambda.AccessPoint
s3_access_point_arn = access_point.s3_access_point_arn

import software.amazon.awscdk.services.s3objectlambda.alpha.*;

AccessPoint accessPoint;
String s3AccessPointArn = accessPoint.getS3AccessPointArn();

using Amazon.CDK.AWS.S3ObjectLambda.Alpha;

AccessPoint accessPoint;
var s3AccessPointArn = accessPoint.S3AccessPointArn;

import s3objectlambda "github.com/aws/aws-cdk-go/awscdks3objectlambdaalpha"

var accessPoint AccessPoint
s3AccessPointArn := accessPoint.S3AccessPointArn

This is only supported for AccessPoints created in the stack - currently you're unable to get the S3 AccessPoint ARN for imported AccessPoints. To do that you'd have to know the S3 bucket name beforehand.
