Om
Om is a frontend state management library and reactive user interface framework that integrates ClojureScript functional programming with the React virtual DOM rendering engine. It provides a bridge to build responsive web interfaces where visual elements automatically update when underlying application data changes.
The project centers on a normalized state store that flattens complex data structures into a relational format. This data is accessed through a reader-based querying system, which decouples the user interface from the state by allowing components to declare specific data requirements that are resolved through a centralized read function.
State is managed via atomic mutations and transactions, ensuring that global application state transitions trigger targeted re-renders of dependent components. The framework also covers client-server data synchronization, identity-based data resolution, and the ability to render components to strings for server-side content delivery.
Features
- ClojureScript-React Bridges - Integrates ClojureScript functional programming models with the React rendering engine to build reactive user interfaces.
- Reader-Based State Querying - Evaluates specific expressions to extract targeted pieces of application state using a dedicated reading function.
- Frontend State Normalization - Flattens complex nested data structures into a relational format for efficient storage and retrieval within the application state.
- Data Value Normalization - Flattens complex data structures into a relational format and reconstructs them into trees for the interface.
- Expression-Based Data Querying - Evaluates specific expressions to extract targeted pieces of application state using a dedicated reading function.
- Frontend State Management - Implements a centralized state management architecture for handling data flow and synchronization in the browser.
- State Mutations - Implements atomic state mutations to ensure global application state transitions trigger targeted re-renders of dependent components.
- Atomic State Mutations - Implements atomic state mutations to ensure global application state transitions trigger targeted re-renders of dependent components.
- Store Normalization Architectures - Maintains application data in a flat map using unique identities to prevent duplication and simplify updates.
- Declarative Data Fetching - Specifies the exact data a component needs and manages the parameters used to fetch those updates dynamically.
- Functional Reactive Programming Frameworks - Combines functional programming patterns with a reactive rendering engine to automatically update the user interface.
- Identity-Based Data Resolution - Transforms flat data structures into hierarchical trees by resolving references between entities during the rendering phase.
- Reader-Based Querying - Decouples the user interface from state by allowing components to declare data requirements resolved through a centralized read function.
- State-to-UI Mapping - Decouples state from the visual layer by transforming raw application state into formatted data for UI display.
- Global State Managers - Stores shared data in a central location so any component can access it regardless of its position in the tree.
- Reactive UI Frameworks - Provides a framework for building interfaces that automatically update their visual state in response to data changes.
- UI Components - Enables the creation of reusable UI components that encapsulate their own data requirements and identity resolution.
- Virtual DOM Reconciliation - Maps a functional component tree to a real document object model using a diffing engine to update only changed elements.
- User Interface Frameworks - Provides a functional API for interacting with a virtual DOM to create responsive web user interfaces.
- Client-Server State Synchronization - Manages the synchronization and coherence between remote server state and local client caches.
- Transactional Updates - Applies a group of data changes as a single unit to trigger updates across all dependent interface elements.
- Dynamic Query Parameterization - Allows the parameters of a data request to be changed during execution to update displayed information.
- Functional Components - Combines pure functional declarations with stateful lifecycle methods to build a reactive user interface hierarchy.
- Data Merging - Combines new data fragments into the current application state and signals all affected components to refresh.
- Client-Server State Synchronization - Coordinates data requests and updates using a reconciliation process that aligns local state with remote data sources.
- Component State Management - Provides methods for managing component-level data and scheduling visual refreshes.
- React Interface - Powerful interface for building complex React-based applications.
