a super simple, no-nonsense diagramming library written in react that just works

Overview

The React Diagrams library is a flow and process orientated diagramming tool inspired by Blender, Labview, and Unreal Engine. Developed within a modern codebase in TypeScript and React, it offers powerful generics and advanced software engineering principles. Designed for software engineers who aim to rewire programs at runtime and enhance software dynamism, React Diagrams prioritizes fast diagram editing while allowing extensive customization.

Features

  • Typescript and React: Written entirely in TypeScript and React for a modern and efficient codebase.
  • Hackable and Extensible: The entire library, including its core, can be extended and re-assembled to suit specific software needs.
  • HTML Nodes Integration: Provides support for HTML nodes as a first-class citizen for complex input and UX requirements.
  • Process-Oriented Design: Aimed at software engineers looking to enhance software dynamism by rewiring programs at runtime.
  • Fast Diagram Editing: Prioritizes fast and efficient diagram editing to streamline the workflow.
  • Modular Design: Offers a more modular approach, enabling users to import just the core or add extras for enhanced functionality.

Installation

To install React Diagrams, follow these steps:

  1. Run pnpm build in the root directory to build the monorepo packages.
