Crosswalk.Core

Runs Crosswalk maps in .NET. A Crosswalk map is a JSON-to-JSON mapping drawn in the browser with the Crosswalk editor and saved as plain JSON. This package loads one, checks it, and runs it on your data, synchronously or asynchronously.

dotnet add package Crosswalk.Core

using System.Text.Json.Nodes;
using Crosswalk;

var transform = MapTransform.Create(File.ReadAllText("order-to-invoice.map.json")); // checks the map once

JsonObject invoice = transform.Run(JsonNode.Parse(orderJson));

Create a MapTransform once per map and reuse it. It's safe to run from many threads.

Operators that wait

Your own operators are C#. One that has to wait, such as a lookup, is an AsyncValueOperator, and maps that use one run with RunAsync:

var tier = new AsyncValueOperator
{
    Id = "acme.customerTier",
    Label = "Customer tier",
    Category = "acme",
    Inputs = new(1, 1),
    Run = async (args, cancellationToken) => await customers.GetTierAsync(Coerce.ToText(args[0]), cancellationToken),
};

var transform = MapTransform.Create(mapJson, new TransformOptions
{
    Registry = OperatorRegistry.Create(new RegistryOptions { Operators = [tier] }),
    Concurrency = 8, // async calls waiting at once, per run
});

JsonObject output = await transform.RunAsync(input, cancellationToken);

registry.ToCatalog() describes your operators as JSON, so the browser editor can offer exactly what your runtime can run.

It's the same map format, and the same behaviour, as the JavaScript packages: both pass the same conformance suite. Read the documentation for more.
