```

or

```

# Usage

## Simplest form

Getting started is as easy as importing the `SvelteOtp` component and just using it.

<br/>

```js
<script>
    import SvelteOtp from ‘@rohanharikr/svelte-otp’;
</script>

<SvelteOtp />
```

## Controlling the state

You can easily control the state of the value by binding it to the `value` prop.

You can also change the number of inputs through the `numOfInputs` prop.

<br/>

```js
<script>
	import SvelteOtp from ‘@rohanharikr/svelte-otp’;

    let value = 'abc12'

</script>

<SvelteOtp numOfInputs={5} bind:value />
```

You can also restrict it to only accept numbers by adding the `numberOnly` attribute.

Separators can be set through the `separator` prop. Placeholders can be added through `placeholder` prop.

<br/>

```js
<script>
    import SvelteOtp from ‘@rohanharikr/svelte-otp’;

    let value = '12';
</script>

<SvelteOtp
    numberOnly
    bind:value
    separator="-"
    placeholder="********"
/>
```

## Customizing the look

You can style the component however you want by passing one of `inputStyle`, `wrapperStyle`, `separatorStyle` or add custom class names through `inputClass`, `wrapperClass`, `separatorClass`. You can also disable all the default styling by adding the `disableDefaultStyle` attribute.

Here's an example component, styled using [tailwindcss](https://tailwindcss.com/ 'Tailwind css framework')

```js
<SvelteOtp
	inputClass="rounded-md bg-gray-200"
	separatorClass="border-blue-700 text-3xl font-bold"
	separator="-"
/>
```
