Code examples that show how to use Lambda with an AWS SDK.

The AWS SDK for JavaScript V3 API Reference Guide describes in detail all the API operations for the AWS SDK for JavaScript version 3 (V3). AWS Lambda is a serverless compute service that lets you run code without provisioning or managing servers, creating workload-aware cluster scaling logic, maintaining event integrations, or managing runtimes. The JavaScript API for AWS Lambda is exposed through the LambdaService client class. Here are a list of examples that demonstrate how to create and use Lambda functions with the AWS SDK for JavaScript v3:

2 weeks ago - To get started with AWS Lambda, first, you create your function by uploading your code (or building it right in the Lambda console) and choosing the memory, timeout period, and AWS Identity and Access Management (IAM) role. Then, you specify the AWS resource to trigger the function, which can be a particular Amazon S3 bucket, Amazon DynamoDB table, or Amazon Kinesis stream.

The following code examples show how to use the basics of Lambda with AWS SDKs.
