This repository is a curated list of AWS Lambda Layers, serving developers who need to package and share common code, dependencies, or runtimes across multiple Lambda functions. It provides a centralized resource for discovering and utilizing pre-built layers for various languages, utilities, and monitoring tools, simplifying serverless development and promoting code reuse.

How It Works

The project functions as a comprehensive catalog of AWS Lambda Layers. It categorizes layers by their primary purpose, such as Runtimes (e.g., C++, Rust, Node.js variants, PHP, Perl), Utilities (e.g., FFmpeg, ImageMagick, AWS CLI, Git), and Monitoring (e.g., Datadog, Instana, Lumigo). Each entry typically includes the layer's ARN or a link to its repository, compatible runtimes, and version information, enabling users to quickly find and integrate necessary components into their serverless applications.

Quick Start & Requirements

• To use a layer, reference its ARN in your AWS Lambda function configuration (via AWS Console, CLI, SAM, or Serverless Framework).
• No direct installation or code execution is required for this repository itself; it's a reference list.

Highlighted Details

• Extensive coverage of custom runtimes for languages like C++, Rust, Bash, Ballerina, Crystal, Nim, Perl, and PHP.
• A wide array of utility layers for tasks such as image manipulation (GraphicsMagick, ImageMagick), data processing (Pandas, GDAL), and system tools (Git, FFmpeg).
• Comprehensive list of monitoring and tracing layers from providers like Datadog, Epsagon, Instana, Lumigo, and Thundra.
• Includes official AWS Lambda Layers like AWSLambdaPowertools for Python and TypeScript.

Maintenance & Community

• The project is sponsored by cloudash.dev.
• The README provides links to various tutorials on creating, using, and sharing Lambda Layers with tools like Serverless Framework, SAM, and the AWS CLI.

Licensing & Compatibility

• The licensing of individual layers varies, as they are community-contributed or provided by third parties. Users must check the license of each specific layer they intend to use.
• Compatibility is primarily dictated by AWS Lambda's layer specifications and the runtimes supported by each individual layer.

Limitations & Caveats

• This is a curated list, and the availability, maintenance status, and versioning of individual layers are dependent on their respective maintainers.
• Users are responsible for verifying the security and compatibility of any third-party layer before integrating it into production environments.
