Say goodbye to the virtual DOM — the new generation of frameworks are all about reactivity at the core. Preact Signals, Solid.js, and Qwik are leading the charge.
⚡ What Are Signals?
Signals are reactive primitives that track and respond to changes in state directly, without needing a full re-render cycle. They:
Eliminate the virtual DOM diffing overhead
Enable fine-grained reactivity
Scale better in complex UIs
🌟 Framework Highlights
Preact Signals – Minimal and fast. Integrates with the Preact ecosystem.
Solid.js – Uses JSX but compiles to pure functions. Super-fast and fine-grained.
Qwik – Focused on resumability. Delivers minimal JS to the browser, and runs instantly on interaction.
🧩 Why It’s a Big Deal
Better performance out of the box
Optimized for edge and mobile environments
Reduces JS payloads dramatically
🔍 Use Cases
Real-time dashboards
Interactive tools on low-power devices
Apps where Time to Interactive (TTI) is mission-critical
If you’re looking to build fast, reactive UIs without bloated bundles — Signals might be your new best friend.
