The concept of "signals," used in frameworks like Angular, Vue, and SolidJS for managing client-side state, is being explored in React through an experimental hook called use-signals. This approach aims to bring fine-grained control over UI re-renders in React, similar to other frameworks.
- Signals are variables that auto-track where they’ve been used and update UI states automatically upon changes, differing from React's useState which requires setter functions
- In React, use-signals allow declaring signals outside components, managing state updates more granularly while still adhering to React's core principles
- The TC39 proposal for signals has reached stage 1, suggesting potential future native support in JavaScript, which could standardize signal implementation across frameworks
