## Introduce

Facebook in-app browsers experience a lot of inconvenience because they cannot be linked to existing browsers.
In particular, some functions such as WebRTC cannot be used, so the user can have a bad experience, so check in advance.
I created this library to encourage users to leave Facebook and turn on their browsers to enter.

## Install

```bash
npm i detect-facebook-in-app-browser # npm

yarn add detect-facebook-in-app-browser # yarn
```

## Usage

```ts
import isFacebookInAppBrowser from 'detect-facebook-in-app-browser';

if (isFacebookInAppBrowser()) {
  // do something...
}
```
