Analysis of Key Technical Principles for a Visual Drag-and-Drop Component Library - 2
- This article complements a prior piece on technical principles for a visual drag-and-drop component library, adding functionalities like Drag Rotation, Copy, Paste, Cut, Data Interaction, and Publishing.
- For Drag Rotation, the Math.atan2() function is utilized to calculate the rotation angle based on mouse movements and the component's center.
- Issues with Zoom In and Out after rotation are addressed by associating zoom calculations with the rotation angle for accurate resizing.
- Automatic Snapping now considers the size and displacement of rotated components to ensure correct snapping behavior.
- Cursor directions are now dynamically matched with component angles for accurate dragging feedback.
- Copy, Paste, and Cut functions facilitate component duplication and manipulation through key commands or right-click operations.
- Different methods for Data Interaction are discussed, including using APIs for component data retrieval and displaying backend-sourced information.
- Publishing options include rendering component data as HTML or extracting a standalone runtime with custom components for efficient deployment.
- Lazy Loading of custom components and versioning for component updates are highlighted as strategies for managing complex component libraries.
- The article references related topics like Math calculations, matrix representation of rotations, and useful projects for implementation.
