input textの内容が変わるたびにAPIを叩きたいが、毎回叩くのは重たいので1秒に1回に制限したい、どのようなコードにする？SolidJS

You can use the debounce function to limit the frequency of API calls. Here's an example of how to implement this in SolidJS:

1. First, install the solid-js and solid-js/web packages if you haven't already:

npm install solid-js solid-js/web

2. Create a debounce function:

function debounce(fn, delay) {
  let timeout;
  return function (...args) {
    clearTimeout(timeout);
    timeout = setTimeout(() => fn.apply(this, args), delay);
  };
}

3. Use the debounce function in your SolidJS component:

import { createEffect, createSignal } from "solid-js";

function App() {
  const [inputText, setInputText] = createSignal("");
  const [result, setResult] = createSignal("");

  const handleInputChange = debounce(async (value) => {
    // Call your API here
    const response = await fetch(`https://your-api.com?input=${value}`);
    const data = await response.json();
    setResult(data.result);
  }, 1000);

  createEffect(() => {
    handleInputChange(inputText());
  });

  return (
    <>
      <input
        type="text"
        value={inputText()}
        onInput={(e) => setInputText(e.target.value)}
      />
      <div>{result()}</div>
    </>
  );
}

export default App;

In this example, the handleInputChange function is debounced with a 1-second delay. The function will only be called once every second, even if the input text changes more frequently.
