Leva
Leva est un panneau de contrôle GUI React et un éditeur de paramètres en temps réel utilisé pour surveiller et ajuster l'état et les variables de l'application sans modifier le code ni recharger la page. Il fonctionne comme un débogueur d'état dynamique et une bibliothèque d'entrée extensible qui fournit une interface visuelle pour affiner les valeurs numériques, booléennes et textuelles au sein d'une application web en cours d'exécution.
Le projet se distingue par un système de plugins qui permet la création de composants d'entrée personnalisés et de comportements spécialisés pour prendre en charge des types de données uniques. Il utilise l'inférence de type pour mapper automatiquement les données au widget visuel approprié, bien que ce mappage puisse être outrepassé pour forcer des types d'entrée spécifiques.
L'interface prend en charge diverses catégories d'entrée, notamment les plages numériques, les vecteurs, les sélecteurs de couleur et les champs de téléchargement de médias. Les contrôles peuvent être organisés en dossiers hiérarchiques, affichés conditionnellement en fonction d'autres valeurs et synchronisés avec des magasins de données externes. Le système surveille également le cycle de vie de l'édition, permettant des rappels lorsque les utilisateurs commencent et terminent leurs interactions pour optimiser les performances des opérations coûteuses.
Features
- Interactive Control Panels - Provides a fully interactive control panel for real-time parameter tuning and application state monitoring.
- Plugin-Based Input Extensions - Ships a diverse collection of input widgets and a plugin system for creating custom data controls.
- Custom Debug Panels - Provides custom debug panels for testing value ranges and configurations during the development process.
- Dynamic UI Debuggers - Acts as a runtime utility for inspecting and modifying user interface parameters and application state in real time.
- Real-Time Application Prototyping - Enables rapid iteration of UI behaviors by linking live controls to internal application logic and state.
- Real-Time Variable Controllers - Implements a graphical interface for the real-time manipulation of application variables during development.
- Object State Syncing - Synchronizes interface values from external sources and reads current states to maintain consistency with application logic.
- Creative Coding Frameworks - Facilitates the management of complex numerical and color parameters typical in creative coding and interactive graphics.
- Plugin Extenders - Supports extending the core application functionality by loading custom input types and behaviors via a plugin system.
- Dynamic UI Generators - Dynamically generates the control interface based on a configuration object defining input types and constraints.
- Global State Stores - Uses a centralized data store to synchronize external application variables with the internal UI state.
- Custom Data Input Components - Provides a plugin system for developing specialized visual widgets to handle unique data types.
- Custom Component Extensions - Enables developers to integrate custom React components as specialized input widgets within the control panel.
- Custom Input Overrides - Provides the ability to replace default input components with custom plugin implementations for unique data types.
- Real-Time Data Editors - Provides a real-time data editor that allows users to modify application variables and see results immediately reflected.
- Type-Inferred Widget Mapping - Automatically maps data types to the most appropriate visual widget, such as sliders for numbers or checkboxes for booleans.
- Value Change Triggers - Triggers custom callbacks when values are modified or when users start and end editing interactions.
- State Lifecycle Callbacks - Triggers callbacks when a user starts and finishes interacting with a control to optimize performance for expensive operations.
- Interaction Lifecycle Interception - Allows optimization of expensive operations by tracking when a user starts and finishes interacting with a control.
- Controller-Initiated State Updates - Allows updating the control panel's state programmatically via getter and setter methods from external application logic.
- Reactive Input Schema Updates - Updates available controls and their schema automatically when external variables or application state change.
- Conditional Input Logic - Provides dynamic form behaviors that show or hide specific input fields based on the current state of other controls.
- Media and Color Inputs - Ships integrated color pickers with multiple format support and image upload fields that return data URLs.
- Numeric Inputs - Provides specialized numerical inputs including sliders and joystick controls for adjusting single values, ranges, and vectors.
- Multi-Store Panel Instances - Supports generating separate visual interfaces tied to distinct data stores to organize variables into different groups.
- Text Input Fields - Includes various text and choice inputs such as text areas, boolean toggles, and labeled dropdown menus.
- Input Change Observers - Allows executing custom logic on input changes to update targets imperatively without triggering full component rerenders.
- User Interface - React-first components GUI.
