⚠️ This package depends on the motion library.

Using AnimateNumber

The AnimateNumber component applies a smooth animation effect when numeric values change. It enhances user experience when numbers increase or decrease.

Basic Usage

import { AnimateNumber } from "@fewings/fancy-react/AnimateNumber";

function Counter() {
  const [count, setCount] = useState(0);

  return (
    <div>
      <AnimateNumber value={count} />
      <button onClick={() => setCount(count + 1)}>Increase</button>
      <button onClick={() => setCount(count - 1)}>Decrease</button>
    </div>
  );
}

Adjusting Animation Speed

<AnimateNumber
  value={count}
  countDur={0.8} // Number counting animation duration (seconds)
  sizeDur={0.5} // Width change animation duration (seconds)
/>

Number Formatting

You can display numbers in your desired format:

<AnimateNumber value={price} format={(value) => `$${value.toLocaleString()}`} />

Applying Styles

You can style it like a regular div element:

<AnimateNumber
  value={score}
  style={{
    fontSize: "2rem",
    fontWeight: "bold",
    color: "#2563eb",
  }}
/>

AnimateNumber Props

| Property | Type | Default | Description | | ---------- | --------------------------- | ----------------- | ---------------------------------------- | | value | number | Required | Numeric value to display | | countDur | number | 0.5 | Number counting animation duration (sec) | | sizeDur | number | 0.3 | Width change animation duration (sec) | | format | (value: number) => string | (v) => \${v}`` | Function to format the number |

Additionally, the component supports all standard properties of a div element.

How It Works

The AnimateNumber component works internally as follows:

1. Detects transitions when a number changes from a previous value to a new one.
2. Animates each digit of the number individually.
3. Applies appropriate animation effects based on the direction when numbers increase or decrease.
4. Applies smooth sizing animations when width changes are needed.
