# MMM-WebView: A WebView module for MagicMirror²

This is a module for the [MagicMirror²](https://github.com/MichMich/MagicMirror/).

MMM-WebView allows you to add a webview which can display any url.

This module uses the [Electron's \<webview\> tag](https://www.electronjs.org/docs/api/webview-tag) instead of `<iframe>` to embed pages.
It makes possible to display pages that cannot be displayed in a `<iframe>`.

## Installation

1. Clone this repository in your `modules` folder:

```bash
cd ~/MagicMirror/modules
git clone https://github.com/Iketaki/MMM-WebView.git
```

2. Add the following configuration block to the modules array in the `config/config.js` file:

```js
let config = {
  modules: [
    {
      module: 'MMM-WebView',
      position: 'top_center',
      config: {
        url: 'https://www.google.com/',
        width: '640px',
        height: '480px',
      },
    },
  ],

## Motivation

When considering about embedding websites to MagicMirror, some websites cannot be embedded using iframe.

There are several reasons, one of that is HTTP response header `X-Frame-Options: DENY` by the websites makes iframe disable. This is needed for the internet security.

For MagicMirror usage, using WebView instead of iframe may resolve the problem.
