Serverless Workflow .NET SDK

The official .NET SDK for the Serverless Workflow DSL.

The SDK is composed of three Nuget packages:

• Core, which contains the models of the Serverless Workflow DSL
• Builders, which contains service used to build workflow definitions programmatically
• IO, which contains the services used to read and write workflow definitions

Installation

Core:

dotnet add package ServerlessWorkflow.Sdk

Builders:

dotnet add package ServerlessWorkflow.Sdk.Builders

IO:

dotnet add package ServerlessWorkflow.Sdk.IO

Example usage

Building a workflow definition programmatically:

var definition = new WorkflowDefinitionBuilder()
    .WithName("fake-workflow")
    .WithVersion("0.1.0:fake")
    .Do("todo-1", task => task
        .Call("http")
        .With("method", "get")
        .With("uri", "https://fake-api.com"))
    .Build();

Reading and writing a workflow definition:

using var inputStream = File.OpenRead("workflow.yaml");
var reader = WorkflowDefinitionReader.Create();
var workflow = await reader.ReadAsync(inputStream);

using var outputStream = File.Create("workflow.yaml");
var writer = WorkflowDefinitionWriter.Create();
await writer.WriteAsync(workflow, stream, WorkflowDefinitionFormat.Yaml);
