LambdaSharp (v0.8.3.5) - Serverless .NET on AWS
LambdaSharp is a CLI and framework for serverless .NET Core application development on AWS. LambdaSharp uses a simple declarative syntax to generate sophisticated CloudFormation templates that provide simple, yet flexible, deployment options.
The objective of LambdaSharp is to accelerate the development pace of serverless solutions while helping developers adhere consistently to best practices to create scalable, observable, and modular systems.
Install LambdaSharp CLI
The LambdaSharp CLI is installed as a .NET Global Tool.
dotnet tool install -g LambdaSharp.Tool Once installed, a deployment tier must be initialized.
lash init --quick-start Deploy a LambdaSharp Module
Creating modules with Lambda functions and deploying them only requires a few steps.
# Create a new LambdaSharp module lash new module MySampleModule # Add a function to the LambdaSharp module lash new function MyFunction --type generic # Deploy the LambdaSharp module lash deploy The LambdaSharp CLI uses a YAML file to compile the C# projects, upload artifacts, and deploy the CloudFormation stack in one step. The YAML file describes the entire module including the inputs, outputs, variables, resources, and functions.
Module: My.SampleModule 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 sealed 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(); } } } License
