# Installation

## Installing with a Package Manager

It can be installed as an npm package.

{% hint style="info" %}
This package can only be used in a web environment and cannot be used in Android or iOS hybrid apps (Webview).
{% endhint %}

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

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

{% endtab %}

{% tab title="yarn" %}

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

{% endtab %}
{% endtabs %}

Once the installation is complete, you can check that it has been added under "dependencies" in your package.json file as shown below:

```json
{
  "dependencies": {
    "@wepin/sdk-js": "^0.0.1"
  }
}
```

Once the installation is complete, initialize the wepinSDK instance using the App ID and App Key assigned after registering the app. This will enable the use of WepinSDK.

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

{% hint style="danger" %}
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 initWepin = async () => {
    const { WepinSDK } = await import('@wepin/sdk-js');
    const wepinSDK = new WepinSDK({
        appKey: '',
        appId: '',
    });
    await wepinSDK.init({
        defaultLanguage: 'ko',
    });
}
```

{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.wepin.io/en/widget-integration/web-javascript-sdk/widget/installation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
