Flowy
Flowy is a JavaScript library designed for building interactive, drag-and-drop flowchart interfaces. It enables the creation of canvas-based environments where users can arrange blocks to design custom logic sequences, decision trees, and visual process maps.
The library provides a structured approach to diagramming by organizing elements into a hierarchical parent-child tree. It features coordinate-based snapping logic to ensure blocks automatically align into organized layouts during user interaction. To support complex system configurations, the tool includes event-driven callback hooks that allow developers to trigger custom logic during the movement and connection of workflow blocks.
The system facilitates the management of diagram data by converting visual arrangements into structured JSON format. This serialization capability allows for the export and import of workflow states, enabling users to save their progress and reload diagrams for future modification.
