Async Transactions for Signals: Batching Updates Across await

The provided code snippets demonstrate how to handle multi-step updates across await operations in React and Vue using a custom signal system. This approach ensures that UI transitions are smooth by deferring less urgent state updates until the more critical ones have completed.

Multi-Step Updates Across await in React

In React, you can use the startTransition function to defer non-critical state updates when dealing with asynchronous operations. Here's how it works:

1. Define Signals and Hooks: Use a custom signal system (signal, useSignalRef) to manage state.
2. Transaction Management: Wrap multi-step data updates in an async transaction.

Example Code

javascript
 
1import { signal, useSignalRef } from './react-adapter';
2
3// Define signals for state management
4const a = signal(0);
5const b = signal(0);
6
7export function Counter() {
8  const va = useSignalRef(a); // React ref to the signal value
9  const vb = useSignalRef(b); // React ref to the signal value
10
11  async function run() {
12    await transaction(async () => {
13      a.set(va.value + 1);
14      await new Promise(resolve => setTimeout(resolve, 200
