Soenneker.Blazor.Drawflow is a lightweight, modern Blazor wrapper for drawflow.js, enabling interactive node-based diagrams in your Blazor applications. It supports advanced features like modules, zoom, import/export, and full event handling.

Demo

Features

  • Node and Connection Management: Add, remove, and update nodes and connections programmatically.
  • Modules: Organize nodes into modules and switch between them.
  • Zoom & Pan: Built-in zoom controls and canvas panning.
  • Import/Export: Serialize and restore flows as JSON.
  • Event Handling: Subscribe to all major events (node created, removed, selected, data changed, etc).
  • Customizable: Pass options to control rerouting, curvature, zoom limits, and more.
  • CDN or Local Assets: Load drawflow.js and CSS from CDN or local files.

Installation

dotnet add package Soenneker.Blazor.Drawflow

Quick Start

  1. Register Services (in Program.cs):
builder.Services.AddDrawflowInteropAsScoped();
  1. Add the Component (in your .razor file):
<Drawflow @ref="Flow" Options="_options" OnNodeCreated="HandleNodeCreated" style="height:400px"></Drawflow>

@code {
    private Drawflow? Flow;
    private readonly DrawflowOptions _options = new();

    private Task HandleNodeCreated(string id)
    {
        Console.WriteLine($"Node created {id}");
        return Task.CompletedTask;
    }
}

Event Callbacks

<Drawflow
    @ref="Flow"
    Options="_options"
    OnNodeCreated="HandleNodeCreated"
    OnNodeRemoved="HandleNodeRemoved"
    OnConnectionCreated="HandleConnectionCreated"
    OnDataChanged="HandleDataChanged"
    ... />

Programmatic API

await Flow.AddNode("github", 1, 1, 150, 150, "github", new { name = "GitHub" }, "<div>GitHub</div>");
await Flow.AddConnection("github", "slack", "output", "input");
await Flow.ZoomIn();
await Flow.Export();

Options

var options = new DrawflowOptions {
    Reroute = true,
    Curvature = 0.3,
    Zoom = 1.0,
    ZoomMax = 2.0,
    ZoomMin = 0.3,
    DraggableInputs = true,
    UseUuid = true,
    ManualCreate = false // auto-create on render
};
