MeshWeaver.Kernel.Hub
Overview
MeshWeaver.Kernel.Hub provides a message hub plugin for a dotnet interactive kernel. It allows notebooks to execute code against remote kernels distributed across the mesh.
Usage
Basic Configuration
var builder = WebApplication.CreateBuilder(args);
// Configure mesh with kernel support
builder.ConfigureMesh(builder =>
builder
.AddKernel()
.ConfigureMesh(config => config.AddMeshNodes(/* your nodes */))
);
var app = builder.Build();
Code Execution Examples
Basic Code Execution
// Execute code through the kernel
var command = new SubmitCode("Console.WriteLine(\"Hello World\");");
client.Post(
new KernelCommandEnvelope(KernelCommandEnvelope.Serialize(
KernelCommandEnvelope.Create(command)))
{
IFrameUrl = "http://localhost/area"
},
o => o.WithTarget(new KernelAddress())
);
Interactive Data Processing
// Example of interactive calculator with UI updates
const string Code = @"
using MeshWeaver.Layout;
using MeshWeaver.Mesh;
using static MeshWeaver.Layout.Controls;
record Calculator(double Summand1, double Summand2);
static object CalculatorSum(Calculator c) =>
Markdown($""**Sum**: {c.Summand1 + c.Summand2}"");
Mesh.Edit(new Calculator(1,2), CalculatorSum)
";
client.Post(
new SubmitCodeRequest(Code) { Id = "Area" },
o => o.WithTarget(new KernelAddress())
);
