The product is keeping layout, widget state and persistence in sync while users drag, resize, undo and reload.

Layout should be one call. layout react angular vue https://grafloria.com/blog/build-a-workflow-editor-in-vue/ https://grafloria.com/blog/build-a-workflow-editor-in-vue/ Sat, 22 Aug 2026 12:00:00 GMT A real workflow editor in Vue: slot-defined nodes, typed ports with connection rules, undo, auto-layout, save/load — v-model all the way down, no framework wrappers. vue tutorial diagrams https://grafloria.com/blog/custom-nodes-without-the-props-mystery/ https://grafloria.com/blog/custom-nodes-without-the-props-mystery/ Sat, 22 Aug 2026 12:00:00 GMT 35,000 developers have viewed two Stack Overflow questions about getting data into and out of custom flow nodes. The confusion is structural — here's the mental model, in React, Vue and Angular. react angular vue https://grafloria.com/blog/draggable-edges-that-stay-routed/ https://grafloria.com/blog/draggable-edges-that-stay-routed/ Sat, 22 Aug 2026 12:00:00 GMT The top-voted react-flow question on Stack Overflow asks whether you can shape edges by dragging them. You can — if bends are model state the router treats as constraints instead of decorations. diagrams edges react https://grafloria.com/blog/obstacle-avoiding-edge-routing/ https://grafloria.com/blog/obstacle-avoiding-edge-routing/ Sat, 22 Aug 2026 12:00:00 GMT Behind router: 'avoid' — a spatial hash over obstacles, a family of grid searches with explicit turn costs, three cache layers, and user waypoints as constraints. The whole pipeline, with the real numbers. engine routing diagrams https://grafloria.com/blog/the-angular-diagram-library-graveyard/ https://grafloria.com/blog/the-angular-diagram-library-graveyard/ Sat, 22 Aug 2026 12:00:00 GMT Angular's most-starred graph library hasn't supported a current Angular for years — its top issue is 'Angular 15 not supported'.

A line that might connect or might pass behind. A label floating near the wrong transition. Diagram bugs your tests never catch — and how an engine can make them impossible. diagrams edges https://grafloria.com/blog/when-mermaid-diagrams-grow-up/ https://grafloria.com/blog/when-mermaid-diagrams-grow-up/ Sat, 22 Aug 2026 12:00:00 GMT Your Mermaid flowchart was perfect at ten nodes. At forty it's an unreadable ribbon with tiny text, and you're adding invisible nodes to trick the layout. Keep the text — make it editable. mermaid diagrams https://grafloria.com/blog/why-nesting-breaks-flow-libraries/ https://grafloria.com/blog/why-nesting-breaks-flow-libraries/ Sat, 22 Aug 2026 12:00:00 GMT Nesting is the most-requested feature in the flow-library world — and the most refused.
