OpenAPI Arazzo Library for dotnet

This project provides a .NET implementation of the OpenAPI Arazzo Specification, allowing you to manage workflows for REST APIs with OpenAPI documents (v3.0+), following the official OpenAPI Arazzo 1.0.0 specification.

The library enables developers to programmatically apply parse, build, serialize, validate arazzo documents.

This library was funded in part by the Interledger Foundation. See the related announcement: SDK Grant Funds Security Features, OpenAPI Specification, and Arazzo Workflow Support in Kiota.

Library

Installing the library

You can install this library via the package explorer or using the following command.

dotnet add <pathToCsProj> package BinkyLabs.OpenApi.Arazzo

Examples

Parsing an Arazzo document

The following example illustrates how you can load or parse an Arazzo document from JSON or YAML.

var (arazzoDocument) = await ArazzoDocument.LoadFromUrlAsync("https://source/arazzo.json");

CLI

Installing the CLI

You can install the Arazzo CLI as a dotnet tool.

dotnet tool install -g BinkyLabs.OpenApi.Arazzo.Tool

Validating an Arazzo document

The validate command loads an Arazzo document and prints any errors or warnings.

clia validate pathOrUrlToArazzoDescription

Use --warnings-as-errors to return an error exit code when warnings are present.

clia validate pathOrUrlToArazzoDescription --warnings-as-errors

Using the GitHub Action

- uses: BinkyLabs/openapi-arazzo-dotnet@v1
  with:
    input: 'arazzo/arazzo.yaml'
    warnings-as-errors: 'true'

Using the container image

docker run --rm \
  -v $(pwd)/arazzo:/app/arazzo:ro \
  ghcr.io/binkylabs/openapi-arazzo-dotnet:1 \
  validate /app/arazzo/arazzo.yaml

Serializing an Arazzo document

The following example illustrates how you can serialize an Arazzo document, built by the application or previously parsed, to JSON.

var arazzoDocument = new ArazzoDocument
{
    Info = new ArazzoInfo
    {
        Title = "Test Arazzo",
        Version = "1.0.0"
    },
    Workflows = new List<ArazzoWorkflow>
    {
        new ArazzoWorkflow
        {
            //...
        }
    }
};

using var textWriter = new StringWriter();
var writer = new OpenApiJsonWriter(textWriter);
document.SerializeAsV1(writer);
var jsonResult = textWriter.ToString();
// or use flush async if the underlying writer is a stream writer to a file or network stream
