# Installation

## Installing with a Package Manager

It can be installed as an npm package.

{% tabs %}
{% tab title="npm" %}

```bash
npm install @wepin/pin-js
```

{% endtab %}

{% tab title="yarn" %}

```bash
yarn add @wepin/pin-js
```

{% endtab %}
{% endtabs %}

Once the installation is complete, initialize the WepinLogin instance using the app ID and app key assigned after registering the app. This will enable the use of WepinPin.

<pre class="language-javascript"><code class="lang-javascript"><strong>// 1. Import the package
</strong>import { WepinPin } from '@wepin/pin-js'
<strong>
</strong>// 2. Initialization
const wepinPin = new WepinPin({
  appKey: 'your-wepin-app-key',
})
</code></pre>

This package is designed to work only in **Client Side Rendering (CSR)** environments. If you are using this package in a Server Side Rendering (SSR) environment, you need to configure it so that the package is loaded only on the client side.

Refer to the following code for implementation:

```javascript
const initWepinPin = async () => {
   const { WepinPin } = await import('@wepin/pin-js');
   const wepinPin = new WepinPin({
       appKey: '',
   });
   await wepinPin.init();
}
```
