Announcement
Preact - Fast 3kB React alternative with the same modern API
A lightweight JavaScript library offering a modern React-like API for building user interfaces, focusing on performance and small bundle size, ideal for projects where speed is critical.
Project Introduction
Summary
Preact is a significantly smaller and faster component-based UI library, built with the same modern API features as React, including components, Virtual DOM, JSX, and Hooks.
Problem Solved
Provides a solution for developers who need the productivity benefits of a declarative, component-based UI library but require a minimal bundle size and faster runtime performance compared to larger alternatives.
Core Features
Tiny Size (3kB)
Minimizes JavaScript payload, leading to faster load times, especially on mobile networks.
React Compatibility
Offers a highly compatible API, allowing developers familiar with React to easily transition or even use many existing React libraries.
Efficient Virtual DOM
Leverages a fast and memory-efficient Virtual DOM implementation for quick UI updates.
Components and JSX
Supports building UIs with reusable components and familiar JSX syntax.
Tech Stack
使用场景
Preact shines in scenarios where performance, size, and speed are paramount, while still providing a productive development experience:
Scenario 1: Building Performance-Sensitive Web Applications
Details
Ideal for creating single-page applications (SPAs) or complex websites where initial load time and runtime performance are critical factors, especially targeting mobile users.
User Value
Delivers a faster user experience and potentially improves SEO metrics related to page speed.
Scenario 2: Integrating UI into Existing Projects
Details
Excellent for adding interactive UI components (like widgets, forms, or small modules) to legacy or non-React websites without adding significant overhead.
User Value
Allows leveraging modern component-based development for specific parts of a site without a full framework rewrite.
Scenario 3: Creating Fast Static Site Generator Frontends
Details
Perfect for pairing with static site generators where the final JavaScript bundle size directly impacts hydration time and performance after the initial HTML load.
User Value
Contributes to quicker interactive states for static content.
