In sintesi

Preact is a minimal React-compatible library optimized for performance and bundle size. Used by developers building lightweight applications, mobile web apps, and performance-critical UIs. Drop-in replacement for React in many cases. Junior: $75k–$105k; mid: $130k–$180k; senior: $190k–$270k. Learning takes 1–2 weeks. Sits between vanilla JavaScript and full React ecosystems.

Cos'è Preact Lightweight

Preact is a minimal, React-compatible JavaScript library for building user interfaces. It provides the same JSX syntax and hooks API as React but is only 3KB gzipped, 95% smaller. Preact is ideal for applications where bundle size and performance are critical: mobile web, progressive web apps, embedded UIs, and applications with strict performance budgets. Preact includes a virtual DOM, components, hooks, and a router. It's designed to be simple and fast, reducing overhead while providing familiar React patterns. It can be used as a drop-in replacement for React in many applications.

❓ Domande frequenti

What is Preact?
Preact is a lightweight, React-compatible JavaScript library for building user interfaces. It's 95% smaller than React (3KB vs 40KB) and mostly compatible with React's API, making it ideal for performance-critical applications.
Is Preact fully compatible with React?
Mostly. Preact supports JSX, hooks, and most React patterns. Some libraries (like Redux) require adapters. Class components are not supported. For most apps, it's a drop-in replacement.
When should I use Preact instead of React?
Use Preact when bundle size matters: mobile web, performance budgets <50KB, IoT devices, or embedded UIs. For large SPAs with complex ecosystem needs, React may be better.
Can I use React libraries with Preact?
Many React libraries work with Preact via compatibility aliases. Some don't. Test before committing to Preact if you rely on specific React libraries.
What's the performance difference?
Preact renders faster and has smaller bundle size. For most apps, the difference is negligible. Preact shines in resource-constrained environments.
