React Content Loader
This project is a React skeleton loader library and UI component set used to create animated SVG placeholder shapes that represent loading content in user interfaces. It functions as an SVG loading placeholder generator designed to prevent layout shifts by signaling data loading states.
The library includes a custom loader design tool for building bespoke skeleton shapes that match specific interface layouts. It employs a rendering approach with static SVG keys to ensure the components are compatible with client-server hydration, preventing mismatches between server-side and client-side rendering.
The system provides capabilities for loading state customization, allowing for adjustments to placeholder colors, animation speeds, and layout directions. It supports both the use of predefined geometry presets and the creation of custom SVG shapes to maintain visual consistency during data fetching.
Features
- Skeleton Loaders - Provides a system for rendering SVG placeholder shapes to indicate that content is currently loading.
- Hydration Key Mappings - Assigns hardcoded keys to SVG gradient definitions to prevent ID mismatches during client-server hydration.
- SVG-Based Vector Rendering - Utilizes scalable vector graphics to render placeholder geometries that remain proportional across screen sizes.
- React Components - Ships reusable loading indicator components specifically designed for the React ecosystem.
- Loading Skeletons - Creates SVG placeholders that mimic the layout of loading content to improve perceived performance.
- Client-Side Hydration - Ensures consistent loading animations between server-side and client-side rendering using static SVG keys.
- Server-Side Rendering Utilities - Prevents hydration mismatches in React apps by using stable keys for SVG elements rendered on the server.
- Hydration Mechanisms - Implements a mechanism using static keys to prevent SVG hydration mismatches between server and client.
- Geometry Presets - Provides predefined layout configurations that map to specific SVG coordinates for rapid skeleton generation.
- Design Tools - Includes a dedicated tool for building bespoke skeleton shapes that match specific interface layouts.
- Loading Screen Customizers - Provides controls for adjusting placeholder colors, animation speeds, and layout directions.
- Placeholder Generators - Ships a tool for building custom SVG shapes to match specific layout geometries for skeleton animations.
- CSS Animation Patterns - Implements a moving highlight effect using pure CSS keyframe animations for skeleton shimmer.
- Loaders and Progress - SVG-based placeholder loading components.
