Visual Drag Demo
This is a low-code visual drag-and-drop editor project for building web page layouts. It provides a canvas-based environment where users can assemble pages by placing, resizing, and rotating pre-built UI components through direct mouse interaction.
The editor includes a grid-based alignment system that snaps components to invisible grid lines or other component edges for precise positioning. Components can be grouped into single units or locked in place to prevent accidental movement, and animations or custom actions can be bound to user interactions like clicks or hovers. An undo-redo command stack records each editing action, allowing users to reverse or reapply changes.
The project also supports fetching dynamic content from external APIs and binding it to component data models, and includes a live preview that renders the current design alongside the ability to export the underlying HTML, CSS, and JavaScript code for deployment.
Features
- Drag-and-Drop Page Builders - Assembles page layouts by placing pre-built components onto a design surface and arranging them visually.
- Mouse-Based Transformations - Provides direct mouse-based resizing and rotation of placed UI components on the canvas.
- Canvas-Based Component Renderers - Renders components by placing them onto a free-form canvas using absolute positioning and mouse events.
- Low-Code Development Platforms - Builds web interfaces by dragging and dropping components onto a canvas instead of writing code manually.
- Canvas State Code Generators - Transforms the current canvas state into deployable HTML, CSS, and JavaScript code.
- Live Design Previews - Renders the current design in a live preview and generates the underlying code for deployment.
- Drag-and-Drop Page Editors - Lets users build web page layouts by dragging, resizing, and configuring pre-built components on a canvas.
- Property Bindings - Links component visual properties to a central data model that updates the UI on property changes.
- React Component Canvas Editors - Places pre-built UI components onto a design surface by dragging them from a palette.
- Component-Based Page Layouts - Creates web pages by composing reusable UI blocks that can be resized, rotated, and grouped.
- Undo-Redo History - Implements an undo-redo command stack that records each editing action for reversal or reapplication.
- Design Preview and Code Export Systems - Renders the current design in a live preview and generates the underlying code for deployment.
- Grid-Based Alignment Systems - Snaps component edges to invisible grid lines or other component boundaries for precise positioning.
- Component Locking Mechanisms - Prevents a component from being moved or edited until it is unlocked.
- Component Grouping and Ungrouping Tools - Combines multiple selected components into a single unit or breaks them apart for independent editing.
- Component Events - Connects user interactions like clicks or hovers to components so they trigger custom actions.
- Event-Driven Interaction Handlers - Triggers component animations and custom actions by attaching event listeners to user interactions.
- Grid Snapping - Aligns components to invisible grid lines or other components for precise positioning.
- Component Grouping and Locking State Machines - Manages component state transitions between grouped, locked, and editable modes using a finite state machine.
- Low-Code and Visual Builders - Drag-and-drop platform for generating web pages.
