The Angular diagram library that speaks signals
Flow charts, node editors and dashboards as Angular components — [(nodes)]/[(edges)] two-way signal bindings, ng-template custom nodes, verified zoneless. And the hard parts are in the box: obstacle-avoiding routing, auto-layout, undo/redo, collaboration, vector export. MIT.
import { Component, signal } from '@angular/core'; import { DiagramCanvasComponent, GrafloriaNodeDefDirective } from '@grafloria/angular'; @Component({ selector: 'app-flow', imports: [DiagramCanvasComponent, GrafloriaNodeDefDirective], template: ` <grafloria-diagram-canvas [(nodes)]="nodes" [(edges)]="edges" [layout]="'elk'"> <ng-template grafloriaNode="job" let-data="data"> <div class="job-card">{{ data['title'] }}</div> </ng-template> </grafloria-diagram-canvas> `, }) export class FlowComponent { nodes = signal([ { id: 'a', type: 'job', position: { x: 0, y: 0 }, data: { title: 'Extract' } }, { id: 'b', position: { x: 240, y: 0 }, label: 'Load' }, ]); edges = signal([{ source: 'a', target: 'b' }]); }
Why teams pick it
Angular-native, not a wrapper shim
Standalone components, signal inputs, [(nodes)] two-way bindings, ng-template node definitions with template context — and the whole binding is verified zoneless, so it is ready for Angular’s future.
The editor features are included
Minimap, snap & helper lines, marquee, clipboard with cascading paste, command-based undo — plus obstacle-avoiding orthogonal routing and off-thread ELK layout. All MIT, no paid templates.
Collaboration without a sync stack
Per-property CRDT lives in the engine: hand it any transport (BroadcastChannel works serverless for same-browser tabs) and two canvases converge — live cursors and anchored comments included.
Coming from ngx-vflow or JointJS?
ngx-vflow is a lovely lightweight Angular canvas — if you need drag/connect and nothing else, it is genuinely small. Its harder parts (obstacle-avoiding curves, dagre layout) are paid source templates, and undo/export are absent. JointJS+ is deep but commercial per developer. Grafloria ships the whole surface MIT. The comparison table is sourced cell by cell.
