A high-performance, minimal-overhead .NET framework for building AWS Lambda functions with native AOT support. Goa provides lightweight clients for AWS services and streamlined function development patterns.
The AWS SDK for .NET comes with significant overhead that impacts Lambda function performance. Goa addresses these key issues:
- Modern .NET: Built with HttpClientFactory, native AOT support, dependency injection, and source generators
- Performance: Reduces memory allocations and cold start times through minimal dependencies
- Security: Goa only provides only essential operations, preventing accidental misuse
- Native AOT Ready: All libraries support native ahead-of-time compilation for faster cold starts
- Minimal Dependencies: Lean implementations with only essential dependencies
- Type-Safe: Full C# type safety with source generators for enhanced development experience
- Multi-Target: Supports .NET 9.0 and .NET 10.0
The fastest way to get started is using the Goa project templates:
dotnet new install Goa.TemplatesCreate an API Gateway Lambda function:
dotnet new goa.apigw -n "MyFirstGoaProject"
cd MyFirstGoaProjectOr create a DynamoDB stream processing function:
dotnet new goa.dynamodb -n "MyDynamoFunction"
cd MyDynamoFunction# Build the project
dotnet build
