Hyperapp
Hyperapp is a functional JavaScript framework for building hypertext applications. It centers on a state management library and a virtual DOM system that creates in-memory interface representations to apply efficient updates to the browser screen via diffing.
The framework avoids templates and JSX, instead utilizing function composition and dedicated tag wrappers to generate HTML structures and SVG elements. It implements a unidirectional data flow where a central state object is managed through transformation functions.
The system covers declarative UI rendering and functional web interfacing, bridging browser APIs and external events into the state loop. It includes mechanisms for asynchronous side effect execution, subscription-based event binding, and render performance optimizations that delay component updates until dependent data changes.
Features
- Unidirectional State Management - Implements a strict unidirectional data flow where state updates are managed through pure functions.
- Virtual DOM Engines - Uses a virtual DOM system to create in-memory interface representations and apply efficient updates to the browser screen.
- Action-Based State Transitions - Utilizes a pure function to transform the application state based on dispatched action objects.
- Asynchronous Action Handlers - Allows actions to return functions that execute asynchronous tasks and dispatch subsequent state updates.
- Side Effect Handlers - Implements the Elm Architecture's pattern of returning side-effect handlers from actions to manage asynchronous operations.
- Declarative UI Frameworks - Renders a declarative representation of the interface and applies efficient screen updates using a diffing algorithm.
- Declarative UI Paradigms - Renders user interfaces where the visual state is described declaratively and automatically reconciled.
- Functional Components - Builds user interfaces by composing pure functions that return declarative element descriptions.
- Functional Tag Wrappers - Provides dedicated tag wrappers and function composition for generating HTML structures without the use of templates or JSX.
- Virtual DOM Implementations - Maintains memory-based interface representations to optimize browser rendering performance.
- Centralized State Management - Maintains a central state object managed through transformation functions that drive the user interface.
- Lightweight UI Frameworks - A minimalist library for building interactive user interfaces with a central state and functional architecture.
- State Management Libraries - Provides a central state object managed through transformation functions to determine the view.
- Virtual DOM Diffing - Implements algorithms for calculating minimal updates between memory-based tree snapshots and the DOM.
- Virtual DOM Reconciliation - Employs a virtual DOM to calculate minimal updates between state representations and the actual DOM.
- Web Application Frameworks - A framework for building web interfaces using function composition and standard HTML elements.
- Web API Integration - Provides a bridge for the application to interact with various browser APIs and external web services.
- Event Dispatchers - Connects outside events to the application by routing them through a central state loop dispatcher.
- Interface Event Subscriptions - Allows registering callbacks for external triggers, such as keyboard input, based on current state.
- Functional Programming Interfaces - Bridges browser APIs and external events using functional programming interfaces and immutable transformations.
- Rendering Optimizations - Implements mechanisms to reduce computation by delaying the rendering of interface components until their underlying data changes.
- HTML View Composition - Generates user interfaces through function composition and conditional logic to dynamically compose the view based on state.
- Browser API Wrappers - Ships specialized functional wrappers for interacting with browser features like URL history and DOM events.
- State-Driven Event Subscriptions - Connects external browser events to the internal state loop via listeners that trigger actions.
- Lightweight Web Frameworks - Provides a minimal JavaScript framework designed to reduce bundle size for fast, small-scale applications.
- UI Frameworks - Declarative UI with immutable state and pure syntax.
- Inspired By Elm - JavaScript library providing the Elm architecture.
- Elm Inspired Projects - JavaScript library providing the Elm Architecture.
