Fast
FAST is a web components framework and declarative UI library used to build adaptive user interfaces. It functions as a server-side rendering engine and design system implementation, enabling the creation of modular components based on web standards.
The framework focuses on cross-framework component compatibility, allowing user interface elements to remain functional across different front-end frameworks and modern browsers. It implements a design language through a collection of pre-defined visual components to ensure consistency across professional applications.
The system covers state-driven UI rendering by binding JSON state to HTML attributes, as well as conditional content rendering and data collection iteration. It manages application navigation and state propagation through nested custom elements, while supporting incremental content streaming and server-side pre-rendering with hydration.
Features
- Web Standard Renderers - Renders custom elements following web standards to ensure consistent performance and compatibility across all major browsers.
- Custom Elements - Builds modular user interfaces using native browser custom elements to ensure cross-framework compatibility.
- Design System Implementations - Implements a collection of pre-defined visual components and styles to ensure a consistent look and feel across applications.
- Cross-Framework Component Distribution - Ensures user interface elements remain functional and compatible across different front-end frameworks and modern browsers.
- Declarative UI Libraries - Binds JSON state to HTML attributes to automatically update views and manage conditional rendering.
- State-Driven UI Rendering - Connects application state to HTML templates to automatically update views and attributes as the underlying data changes.
- HTML Attribute Bindings - Maps JSON data structures directly to HTML attributes to synchronize component properties and ARIA states.
- Custom Element Renderers - Implements a rendering system specifically for custom elements to support nested trees and shadow DOM standards.
- Design System Implementations - Implements a consistent design language through a collection of pre-defined visual components.
- Component Architecture - Implements an architecture of reusable interface elements to build scalable and accessible professional websites.
- Component-Based Web Frameworks - Provides a framework for building adaptive user interfaces using standard web components and declarative templates.
- HTML Templating Engines - Processes structured template syntax and JSON state to generate dynamic HTML content.
- Static HTML Generators - Converts declarative syntax and state arrays into static HTML through conditional evaluation and list iteration.
- Server-Side Rendering - Generates initial HTML on the server to increase page load speed and search engine visibility before client hydration.
- Web Components - Builds modular and accessible user interface elements that follow web standards for broad browser compatibility.
- Component State Propagation - Distributes a root state tree through nested custom elements by merging it with specific element attributes.
- Design System - Provides a library of reusable, standardized components to maintain a consistent visual language across professional applications.
- Adaptive UI Layouts - Creates flexible web layouts and behaviors that automatically adjust to different environments, devices, and accessibility requirements.
- Collection Iterators - Includes mechanisms for rendering lists by iterating over data collections within HTML templates.
- Conditional Rendering - Provides logic for displaying UI elements based on runtime conditions within markup templates.
- Hydration Node Marking - Implements specialized HTML attributes to mark nodes for efficient client-side event and state attachment during hydration.
- Root State Distribution - Distributes a global state tree through nested custom elements by merging root data with component attributes.
- Hydration Node Marking - Adds specialized attributes to rendered HTML so the client-side runtime can efficiently attach to and patch DOM nodes.
- Client-Side Navigation Management - Manages history-based navigation to create multi-page experiences and application flows using web components.
- Incremental Content Streaming - Sends data to the client in small chunks to allow users to see updates before the full response finishes.
- Component Libraries - Lightweight library for performant, memory-efficient custom elements.
- Design Systems - Library for building performant, standards-compliant design systems.
- UI Component Libraries - Web component-based technology collection for efficient UI building.
