yarn add vuepress-plugin-comment-plus -D
```

With `cnpm`:

### ⚠️Route object properties

**Don't use `window` object directly to get route information**.

Plugin has registered correct route information in `frontmatter.to` object and `frontmatter.from` object. Their properties are the same as [vue-router's route object](https://router.vuejs.org/api/#route-object-properties).

### Use in Waline

The `options` is exactly the same as `Waline` configuration.

```javascript
module.exports = {
  plugins: [
    [
      'vuepress-plugin-comment-plus',
      {
	     choosen: 'waline', 
         // options选项中的所有参数，会传给Waline的配置
         options: {
           el: '#valine-vuepress-comment',
           serverURL: 'your serverURL', //  such as "https://***.vercel.app/"
	       path: '<%- frontmatter.commentid || frontmatter.permalink %>'
         }
      }
    ]
  ]
}
```


### Use in Gitalk

The `options` is exactly the same as `Gitalk` configuration.

```javascript
module.exports = {
  plugins: [
    [
      'vuepress-plugin-comment-plus',
      {
        choosen: 'gitalk', 
        options: {
          clientID: 'GitHub Application Client ID',
          clientSecret: 'GitHub Application Client Secret',
          repo: 'GitHub repo',
          owner: 'GitHub repo owner',
          admin: ['GitHub repo owner and collaborators, only these guys can initialize github issues'],
          distractionFreeMode: false 
        }
      }
    ]
  ]
}
```

If you want to access variables, such as `$frontmatter` and `window`, please use **EJS** syntax.

```javascript
module.exports = {
  plugins: [
    [
      'vuepress-plugin-comment-plus',
      {
        choosen: 'gitalk', 
        options: {
          id: '<%- frontmatter.commentid || frontmatter.permalink %>',
          title: '「Comment」<%- frontmatter.title %>',
          body: '<%- frontmatter.title %>：<%-window.location.origin %><%- frontmatter.to.path || window.location.pathname %>',
          clientID: 'GitHub Application Client ID',
          clientSecret: 'GitHub Application Client Secret',
          repo: 'GitHub repo',
          owner: 'GitHub repo owner',
          admin: ['GitHub repo owner and collaborators, only these guys can initialize github issues'],
          distractionFreeMode: false,
        }
      }
    ]
  ]
}
```

**Note**: Never use callback function in plugin configuration, that will be filtered by vuepress. So I have to support EJS syntax.

### Use in Valine

The `options` is exactly the same as `Valine` configuration.

```javascript
module.exports = {
  plugins: [
    [
      'vuepress-plugin-comment-plus',
      {
        choosen: 'valine', 
        options: {
          el: '#valine-vuepress-comment',
          appId: 'Your own appId',
          appKey: 'Your own appKey'
        }
      }
    ]
  ]
}
```

If you want to access variables, such as `$frontmatter` and `window`, please use **EJS** syntax.

```javascript
module.exports = {
  plugins: [
    [
      'vuepress-plugin-comment-plus',
      {
        choosen: 'valine', 
        options: {
          el: '#valine-vuepress-comment',
          appId: 'Your own appId',
          appKey: 'Your own appKey',
          path: '<%- frontmatter.commentid || frontmatter.permalink %>'
        }
      }
    ]
  ]
}
```


### How to hide page comment

If you want to hide comment plugin in specified page, set `$frontmatter.comment` or `$frontmatter.comments` to `false`.

For example:

```yml
---
comment: false 
# comments: false 
---
```

Comment won't appear in the page of this passage. 

## Options Detail

  **Required**.

- **options** `object`
