The countup component is used to display numbers dynamically. It is a great way to make the interface more interactive and engaging. The countup component is a simple and easy way to animate numbers in your application.

To be able to use the countup in your application you will need to install the countup.js dependency with `npm install countup.js`.

## Basic usage

To create a countup, add `data-countup` to any HTML text tag and specify the number which is to be reached. The animation will be triggered as soon as the number enters the viewport.

```html
<h1 data-countup>30000</h1>
```

The results can be seen in the example below.

```html example libs="countup" centered
<h1 data-countup>30000</h1>
```

## Duration

Set the `duration` to determine how long the animation should take. By default, the duration is set to 2 seconds, but you can modify it as you wish.

```html
<h1 data-countup='{"duration":4}'>30000</h1>
```

Look at the example below to see how the duration affects the animation.

```html example libs="countup" centered vertical separated
<h1 data-countup>30000</h1>
<h1 data-countup='{"duration":4}'>30000</h1>
<h1 data-countup='{"duration":6}'>30000</h1>
```

## Starting value

By default the countup will start from zero. If you want to set a different start value use `startVal`.
You can also set the start value to be greater than the final value, so that it counts down instead of up.

```html
<h1 data-countup='{"startVal":12345}'>30000</h1>
```

To see how the starting value affects the animation, look at the example below.

```html example libs="countup" centered vertical separated
<h1 data-countup='{"startVal":12345}'>30000</h1>
<h1 data-countup='{"startVal":47655}'>30000</h1>
```

## Decimal places

Set how many decimal numbers should be displayed using `decimalPlaces`. By default, the number of decimal places is set to 0.

```html
<h1 data-countup='{"decimalPlaces":1}'>3.123</h1>
```

Look at the example below to see how the number of decimal places affects the animation.

```html example libs="countup" centered vertical separated height="20rem"
<h1 data-countup>3.123</h1>
<h1 data-countup='{"decimalPlaces":1}'>3.123</h1>
<h1 data-countup='{"decimalPlaces":2}'>3.123</h1>
<h1 data-countup='{"decimalPlaces":3}'>3.123</h1>
```

## Easing

Disable easing using `"useEasing": false`. Easing is set to `true` by default, so that the animation speed changes over the course of its duration. Easing can be disabled to make the animation linear.

```html
<h1 data-countup='{"useEasing": false}'>30000</h1>
```

Look at the example below to see how easing affects the animation.

```html example libs="countup" centered vertical separated
<h1 data-countup>30000</h1>
<h1 data-countup='{"useEasing": false}'>30000</h1>
```

## Use grouping

Disable grouping using `"useGrouping": false`. Grouping is set to `true` by default, so that the number is displayed with a separator.

```html
<h1 data-countup='{"useGrouping": false}'>30000</h1>
```

Example below shows how grouping affects the animation.

```html example libs="countup" centered vertical separated
<h1 data-countup>30000</h1>
<h1 data-countup='{"useGrouping": false}'>30000</h1>
```

## Separator

You can change the default separator using `separator` and specifying the one you wish to use.

```html
<h1 data-countup='{"separator":" "}'>3000000</h1>
```

This example shows how the separator affects the animation.

```html example libs="countup" centered vertical separated
<h1 data-countup>3000000</h1>
<h1 data-countup='{"separator":" "}'>3000000</h1>
```

## Decimal separator

You can change the default decimal separator using `decimal` and specifying the one you wish to use.

```html
<h1 data-countup='{"decimal":","}'>3.12</h1>
```

Look at the example below to see how the decimal separator affects the animation.

```html example libs="countup" centered vertical separated
<h1 data-countup='{"decimalPlaces":2}'>3.12</h1>
<h1 data-countup='{"decimalPlaces":2,"decimal":","}'>3.12</h1>
```

## Prefix

Set the countup prefix using `prefix` and specifying the prefix you want to add, for instance a currency symbol.

```html
<h1 data-countup='{"prefix":"$"}'>30000</h1>
```

Look at the example below to see how the prefix affects the animation.

```html example libs="countup" centered vertical separated
<h1 data-countup='{"prefix":"$"}'>30000</h1>
<h1 data-countup='{"prefix":"€"}'>30000</h1>
```

## Suffix

Set the countup suffix using `suffix` and specifying the suffix you want to add, for instance a percentage symbol.

```html
<h1 data-countup='{"suffix":"%"}'>300</h1>
```

Look at the example below to see how the suffix affects the animation.

```html example libs="countup" centered vertical separated
<h1 data-countup='{"suffix":"%"}'>300</h1>
<h1 data-countup='{"suffix":"‰"}'>300</h1>
```
