DOCS (wip)

Docs are currently being worked on, along with a migration path.


A flow & process orientated diagramming library inspired by Blender, Labview and Unreal engine.

  • Modern Codebase written entirely in Typescript and React, the library makes use of powerful generics, advanced software engineering principles and is broken up into multiple modules.
  • Hackable and extensible the entire library including its core can be extended, rewired and re-assembled into fundamentally different software to suit your own software needs.
  • HTML nodes as a first class citizen the library was originally written to represent advanced dynamic nodes, that are difficult to represent as SVG's due to complex input requirements ux requirements.
  • Designed for process the library is aimed for software engineers that want to rewire their programs at runtime, and that want to make their software more dynamic.
  • Fast diagram editing the defaults provided give the highest priority to editing diagrams as fast as possible.


Example implementation using custom models: (Dylan's personal code)

Personal Project

Get started with the default models right out of the box:


For all the bells and whistles:

yarn add @projectstorm/react-diagrams

This includes all the packages listed below (and works (mostly and conceptually) like it used to in version 5.0)

A more modular approach

This library now has a more modular design and you can import just the core (contains no default factories or routing)

yarn add @projectstorm/react-diagrams-core

this is built ontop of the evolving react-canvas-core library

yarn add @projectstorm/react-canvas-core

which makes use of

yarn add @projectstorm/geometry

and of course, you can add some extras:

yarn add @projectstorm/react-diagrams-defaults
yarn add @projectstorm/react-diagrams-routing

How to use

Before running any of the examples, please run yarn build in the root. This project is a monorepo, and the packages (including the demos) require the packages to first be built.

Take a look at the diagram demos


Take a look at the demo project which contains an example for ES6 as well as Typescript


Checkout the docs

Run the demos

After running yarn install you must then run: cd diagrams-demo-gallery && yarn run start

Building from source

Simply run yarn then yarn build or yarn build:prod in the root directory and it will spit out the transpiled code and typescript definitions into the dist directory as a single file.

Built with react-diagrams
