λ# is a command line tool and a framework for serverless application development. λ# uses a simple declarative syntax to generate sophisticated CloudFormation templates that provide simple, yet flexible, deployment options.
The objective of λ# is to accelerate the development pace of serverless solutions while helping developers adhere consistently to best practices to create scalable, observable, and modular systems.
If you like or are using this project, please give it a star. Make sure to also check out the documentation site. Thanks!
The λ# CLI is installed as a .NET Global Tool.
dotnet tool install -g LambdaSharp.Tool
Once installed, the λ# CLI needs to be configured.
lash config
Finally, a deployment tier must be initialized with the λ# Core.
lash init --tier Sandbox
Creating modules with Lambda functions and deploying them only requires a few steps.
# Create a new λ# module
lash new module MySampleModule
# Add a function to the λ# module
lash new function MyFunction
# Deploy the λ# module
lash deploy
The λ# CLI uses a YAML file to compile the C# projects, upload assets, and deploy the CloudFormation stack in one step. The YAML file describes the entire module including the inputs, outputs, variables, resources, and functions.
Module: MySampleModule
Items:
- Function: MyFunction
Memory: 128
Timeout: 30
The C# project contains the Lambda handler.
namespace MySampleModule.MyFunction {
public class FunctionRequest {
// add request fields
}
public class FunctionResponse {
// add response fields
}
public class Function : ALambdaFunction<FunctionRequest, FunctionResponse> {
//--- Methods ---
public override Task InitializeAsync(LambdaConfig config)
=> Task.CompletedTask;
public override async Task<FunctionResponse> ProcessMessageAsync(FunctionRequest request) {
// add business logic
return new FunctionResponse();
}
}
}
