Features

• UI Push Updates - Provides real-time delivery of server-side updates to modify user interface elements via Server-Sent Events.
• Server-Driven State Management - Offloads application logic and state transitions to the backend to reduce frontend complexity.
• State Signal Patching - Updates frontend reactive signals using JSON Merge Patch delivered via HTTP or Server-Sent Events.
• DOM Reconciliation - Employs a morphing-based reconciliation engine to update the DOM while preserving element state and focus.
• Event Bindings - Executes JavaScript expressions in response to native DOM events via declarative syntax.
• JSON State Synchronization - Synchronizes frontend and backend state using JSON payloads and partial updates.
• Event Listeners - Binds custom logic to standard DOM events using HTML attributes.
• Reactive UI Updates - Automatically updates user interface elements and signals in response to streaming server-sent events.
• Reactive User Interfaces - Creates dynamic user interfaces that automatically synchronize their state with server-driven updates.
• Signal-Based Reactivity - Uses a signal-based reactivity system to track state and trigger granular UI updates.
• Attribute Binding - Implements a system for dynamically configuring element attributes using reactive expressions.
• Backend Action Triggering - Provides declarative HTML attributes to trigger server-side logic using standard HTTP methods.
• Computed State - Generates read-only reactive signals derived from expressions that update automatically when dependencies change.
• Declarative UI Interactivity - Creates interactive user interfaces using declarative HTML attributes instead of imperative JavaScript.
• DOM Morphing - Updates or removes HTML elements using a morphing strategy to maintain client-side state and performance.
• Event Binding - Maps browser events to reactive expressions using declarative HTML attributes.
• Hypermedia-Driven Development - Implements a hypermedia-driven architectural approach to build interactive web applications.
• Reactive Expression Evaluation - Provides sandboxed JavaScript evaluation within HTML attributes to compute dynamic values from reactive signals.
• Logic Offloading - Moves application logic and state transitions to the backend to reduce frontend complexity.
• SSE-Driven DOM Patching - Streams incremental HTML fragments over a long-lived Server-Sent Events connection to update the UI.
• Over-the-Air Update Services - Uses Server-Sent Events to incrementally update the user interface without page reloads.
• Surgical DOM Update Engines - Updates only the modified parts of the DOM tree to improve rendering performance.
• Real-time Event Streams - Transmits multiple events over a single connection to trigger incremental interface updates or scripts.
• Dynamic Class Management - Conditionally applies or removes CSS classes based on the evaluation of reactive expressions.
• Reactive Text Updates - Enables elements to automatically update their text content based on the current value of reactive signals.
• Global State Managers - Defines globally accessible reactive state variables using declarative HTML attributes.
• State Bindings - Synchronizes HTML input elements with reactive signals to maintain consistency between UI and state.
• Reactive Visibility Toggling - Toggles the visibility of HTML elements based on whether a reactive expression evaluates to true or false.
• Declarative DOM Frameworks - Uses declarative attributes to manage both the DOM state and application state from the server.
• Declarative JavaScript Execution - Enables the invocation of encapsulated JavaScript functions directly through declarative HTML attributes.
• Backend-Driven Updates - Morphs existing HTML elements based on backend responses to change content while preserving state.
• Expression Sandboxes - Provides a sandboxed environment to safely evaluate JavaScript expressions within HTML attributes.
• Remote Script Execution - Enables the execution of JavaScript delivered from the server via content types or SSE.
• State and Element Patching - Modifies HTML elements and frontend state signals based on responses driven by the backend server.
• State-Aware Backend Requests - Sends the current application state with every server request to ensure the backend maintains full context.
• DOM State Preservation - Preserves client-side element state and focus while updating parts of the page from server responses.
• Reactive Signal Bindings - Connects reactive signals to custom element attributes and responds to events dispatched by web components.
