STORM React Diagrams

PSA 2018: React Diagrams ~is currently~ was getting a bit of a rewrite to enable much more advanced features. To see the new foundation WIP visit https://github.com/projectstorm/react-canvas.

PSA 2019: I still want to jump onto the rewrite, but it is a much larger project than anticipated, so going to try maintain this one in the mean time.

RELEASE NOTES : http://dylanv.blog/2018/03/03/storm-react-diagrams-5-0-0/

A super simple, no-nonsense diagramming library written in React that just works.

Example implementation using custom models: Get started with the default models right out of the box:

Introduction

A no-nonsense diagramming library written entirely in React with the help of a few small libraries. It aims to be:

• Simple, and void of any fuss/complications when implementing it into your own application
• Customizable without having to hack the core (adapters/factories etc..)
• Simple to operate and understand without sugar and magic
• Fast and optimized to handle large diagrams with hundreds of nodes/links
• Super easy to use, and should work as you expect it to
• Perfect for creating declarative systems such as programmatic pipelines and visual programming languages

Installing

yarn add @projectstorm/react-diagrams

Run the demos

After running yarn install you must then run: yarn run storybook

Building from source

Simply run webpack in the root directory (or export NODE_ENV=production && webpack if you want a production build) and it will spit out the transpiled code and typescript definitions into the dist directory as a single file. We use webpack for this because TSC cannot compile a single UMD file (TSC can currently only output multiple UMD files).
