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

import aws_cdk.aws_lambda as lambda_
import aws_cdk.aws_s3 as s3
import aws_cdk.aws_s3objectlambda_alpha as s3objectlambda
import aws_cdk as cdk

stack = cdk.Stack()
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"
    }
)

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 aws_cdk.aws_lambda as lambda_
import aws_cdk.aws_s3 as s3
import aws_cdk.aws_s3objectlambda_alpha as s3objectlambda
import aws_cdk as cdk

stack = cdk.Stack()
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",
    supports_get_object_range=True,
    supports_get_object_part_number=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 aws_cdk.aws_lambda as lambda_
import aws_cdk.aws_s3 as s3
import aws_cdk.aws_s3objectlambda_alpha as s3objectlambda
import aws_cdk as cdk

stack = cdk.Stack()
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"
    }
)
