A collection of curated project template to get started with AWS Lambda function written in Swift

Swift On AWS Lambda SAM Templates

This repository contains a collection of AWS SAM (Serverless Application Model) templates tailored specifically for Swift developers. These templates provide a starting point for building serverless applications on AWS using Swift.

Acknowledgments

These templates are based on the aws-samples/aws-sam-swift repository provided by AWS Samples.

Usage

To use these templates, you can initialize a new SAM project directly from this repository using the sam init command with the -l flag pointing to this GitHub repository:

sam init -l gh:swift-server-community/aws-lambda-swift-sam-template

This command will prompt you to choose one of the available templates and set up a new SAM project based on your selection.

Each template contains its README with detailed instructions on how to use it, along with additional information on building, deploying, testing, and deleting the application.

Available Templates

• API to Lambda: Template for creating a Swift-based API using AWS Lambda and API Gateway.
• SQS to Lambda: Template for processing messages from an SQS queue using a Swift-based Lambda function.
• S3 to Lambda: Template for processing S3 events with a Swift-based Lambda function.
• Scheduler to Lambda: Template for scheduling Swift-based Lambda functions to run at specified intervals.

Requirements

• AWS CLI
• AWS SAM CLI
• Docker

Simplify build by using the standard Amazon Linux 2 / Swift docker images

The change to include openssl-devel landed in the Amazon Linux 2 Swift container image build by Apple thanks to swiftlang/swift-docker#371.

It's now time to update the Makefile in each template to simplify and remove the need to build a custom container.

I think just two changes are required (in each template)

1. change the value of DOCKER_IMAGE to swift:5.10-amazonlinux2
   

   aws-lambda-swift-sam-template/templates/api-to-lambda/{{cookiecutter.__project_name}}/Makefile

   Line 18 in d311397

   DOCKER_IMAGE := swift-lambda-builder-workaround

   I assume we only support the latest version of Swift, no more.

2. Delete this line
   

   aws-lambda-swift-sam-template/templates/api-to-lambda/{{cookiecutter.__project_name}}/Makefile

   Line 25 in d311397

   docker inspect $(DOCKER_IMAGE) >/dev/null 2>&1 || docker build -t $(DOCKER_IMAGE) .; \
