@prnt/dagr

The convenience entry point for Dagr. The root exports the graph model; subpaths expose each package without merging conflicting names.

npm install @prnt/dagr react react-dom three   # the renderer and React parts need three

import { Graph } from '@prnt/dagr';
import { layout } from '@prnt/dagr/layout';
// Also available: @prnt/dagr/graph, @prnt/dagr/render, @prnt/dagr/render/core,
// @prnt/dagr/react, @prnt/dagr/vdsl and @prnt/dagr/explorer.

const graph = new Graph();
graph.addNode('source');
graph.addNode('sink');
graph.addEdge('source', 'sink', 'flow');
const result = layout({ graph });

Each entry point forwards the same exports and types as its corresponding @prnt/dagr-* package. @prnt/dagr and @prnt/dagr/graph both forward @prnt/dagr-graph. @prnt/dagr/render/core forwards @prnt/dagr-render/core, the renderer's camera and edge-path arithmetic with no three.js, and @prnt/dagr/explorer forwards @prnt/dagr-explorer, the DOM and SVG graph explorer. Importing the root does not initialize a renderer. The umbrella installs all six packages. For a smaller dependency set, install the scoped packages individually.

ES modules only. The umbrella requires React 19 and React DOM 19. The explorer itself also runs on React 18, so a React 18 site installs @prnt/dagr-explorer directly rather than through the umbrella. three.js (>=0.180.0 <1.0.0) is marked an optional peer: @prnt/dagr/render and @prnt/dagr/react load it, and the root, @prnt/dagr/graph, @prnt/dagr/layout, @prnt/dagr/render/core, @prnt/dagr/vdsl and @prnt/dagr/explorer never do. @prnt/dagr-render marks it optional too, so a site that uses neither of those two entries installs no three.js. Install three yourself to use @prnt/dagr/render or @prnt/dagr/react. See the documentation and the scoped package READMEs for API details and runtime requirements.
