Introducing Swift AWS Lambda Runtime

It is my pleasure to announce a new open source project for the Swift Server ecosystem, Swift AWS Lambda Runtime. Distributed as a Swift package, the Swift AWS Lambda Runtime is designed to help Swift developers build serverless functions for the Amazon Web Services Lambda platform.

The project is a group effort that included engineers across the Swift community, including engineers from Apple and Amazon. Notably Fabian Fett pioneered the work in the community and co-authored the library. As an open source library, anyone interested in contributing to the project can easily join in to help make it better.

The Swift AWS Lambda Runtime is a new open-source Swift package that simplifies building server-less functions for AWS Lambda, enabling Swift developers to create scalable, cost-effective cloud solutions with low memory use and fast startup.

Developed collaboratively by Apple, Amazon, and community engineers like Fabian Fett, it implements the AWS Lambda Runtime API with an embedded HTTP client optimised for performance.

It offers a simple closure based API for quick tasks and a performance oriented EventLoopLambdaHandler API using SwiftNIO for complex, non-blocking event handling.

The AWSLambdaEvents module supports common AWS triggers like SNS, SQS, S3, and APIGateway, using Codable for JSON handling, making it versatile for various server-less workloads. Developers can contribute to this open-source project to enhance its capabilities.
