New Hook: useId

Today we are announcing a new hook: useId. This hook creates stable unique identifiers that are consistent between server-side rendering (using preact-render-to-string) and client-side hydration. The useId() hook is primarily useful for generating identifiers for attributes like aria-labelledby and <label for="...">.

To enable useId() to generate consistent unique identifiers, please ensure you are using preact-render-to-string version 5.2.4 or newer for server-side rendering.

10.10.0

Feature


• Microtick —> setTimeout for debouncing renders (mirror change for setTimeout debounce #3608, thanks @JoviDeCroock)

We changed our debounce of our rendering to setTimeout!
Why? We've batched using microtasks for the past few major versions because it benchmarked well. This had a side-effect of flushing batched renders between event handlers, which can cause some strange behavior:

<input
      type="checkbox"
      onChange={onChange}
      checked={true}
      onClick={onClick}
/>


An additional benefit of this change is that code causing an infinite rendering loop will no longer result in an unresponsive browser tab. Rendering in a loop is now capped to the browser's maximum timer frequency (~250Hz), which makes it possible to pause and debug the code triggering an accidental loop.
