# Vue compatibility
Docsify allows Vue content to be added directly to you Markdown files. This can greatly simplify working with data and adding reactivity to your site.
Docsify allows Vue content to be added directly to you markdown pages. This can greatly simplify working with data and adding reactivity to your site.
To get started, add Vue [2.x](https://vuejs.org) or [3.x](https://v3.vuejs.org) to your `index.html` file:
To get started, add either Vue [2.x](https://vuejs.org) or [3.x](https://v3.vuejs.org) to your `index.html` file:
```html
<!-- Vue 2.x -->
<!-- Vue 2.x (production)-->
<script src="//cdn.jsdelivr.net/npm/vue@2/dist/vue.min.js"></script>
<!-- Vue 3.x -->
<!-- Vue 3.x (production) -->
<script src="//cdn.jsdelivr.net/npm/vue@3/dist/vue.global.prod.js"></script>
```
The URLs above will load a production version of Vue which is optimized for performance. Alternatively, development versions of Vue are larger but offer helpful console warnings and [Vue.js devtools](https://github.com/vuejs/vue-devtools) support:

## Template syntax
Vue [template syntax](https://vuejs.org/v2/guide/syntax.html) can be added directly to your markdown pages. This syntax can be used to generate dynamic content without additional configuration using [JavaScript expressions](https://vuejs.org/v2/guide/syntax.html#Using-JavaScript-Expressions) and Vue [directives](https://vuejs.org/v2/guide/syntax.html#Directives).
Vue [template syntax](https://vuejs.org/v2/guide/syntax.html) is used to create dynamic content. With no additinal configuration, this syntax offers several useful features like support for [JavaScript expressions](https://vuejs.org/v2/guide/syntax.html#Using-JavaScript-Expressions) and Vue [directives](https://vuejs.org/v2/guide/syntax.html#Directives) for loops and conditional rendering.
```markdown
<!-- JavaScript expressions -->
<p>2 + 2 = {{ 2 + 2 }}</p>
<!-- Hide in docsify, show everywhere else (e.g. GitHub) -->
<!-- Hide in docsify, show elsewhere (e.g. GitHub) -->

<!-- Sequenced content -->
<!-- Sequenced content (i.e. loop)-->

## Global options
Use `vueGlobalOptions` to share data, methods, lifecycle hooks, and computed properties throughout your site. These options will be available to Vue content not explicitly mounted via [instance options](#instance-options), [components](#components), or a markdown `<script>`.
Use `vueGlobalOptions` to share Vue options throughout your site. These options will be used when Docsify detects Vue content in the main content area that has not been previously mounted via [instance options](#instance-options), [components](#components), or a [markdown script](#markdown-script). Global `data()` is shared and changes will persist as users navigate the site.

Keep in mind that global `data()` is shared, so changes made in one location will affect all locations where global `data()` is used. These changes will also persist as users navigate your site. To demonstrate, let's render the above counter twice.
Notice the behavior when multilpe global counters are rendered below: changes made to one counter affect the other because both instances reference the global `count` value.

## Instance options
Use `vueOptions` to specify DOM elements to mount as Vue instances and their associated options as `key:value` pairs. DOM elements are specified using [CSS selectors](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors) as the key. Selectors are limited in scope to the main content area
Use `vueOptions` to specify Vue mount elements and their associated options. Mount elements are specified using a [CSS selector](https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Selectors) as the key with an object containing Vue options as their value. Docsify will mount the first matching element in the main content area (`#main, .markdown-section`) each time a new page is loaded. Instance data is not shared and changes will not persist as users navigate the site.
```js
window.$docsify = {
vueOptions: {
"#counter": {
'#counter': {
data() {
return {
count: 0
count: 0,
};
}
computed: {
message() {
const date = new Date();
const hours = date.getHours();
const greeting = hours < 12 ? 'morning' : 'day';
return `Good ${greeting}!`;
}
}
}
}
},
},
},
};
```
```markdown
<div id="counter">
<p>{{ message }}</p>
<button v-on:click="count -= 10">-</button>
<button v-on:click="count -= 1">-</button>
{{ count }}
<button v-on:click="count += 10">+</button>
<button v-on:click="count += 1">+</button>

<button v-on:click="count += 10">+</button>
<button v-on:click="count += 1">+</button>
</output>
## Components
Docsify provides components
Use `vueComponents` to register Vue components using the component name as the key with an object containing Vue options as the value. Components data is not shared and changes will not persist as users navigate the site.

## Markdown script
TBD
Vue content can mounted using a `<script>` tag in your markdown pages.

```html

## Technical Notes
- Docsify processes Vue content in the following order:
1. markdown script,
1. `vueOptions`
1. `vueGlobalOptions`
- Docsify will not mount an element that is already a Vue instance or contains a Vue instance.
- Docsify will automatically destroy/unmount all Vue instances it creates.
- When processing `vueGlobalOptions`, docsify parses each root element of the main content area and mounts the element if Vue content is detected. Docsify does not parse each individual node within the main content area.
- When processing `vueGlobalOptions`, docsify detects the full `v-` attribute syntax (e.g `v-bind:href` or `v-on:click`) but not the [shorthand](https://vuejs.org/v2/guide/syntax.html#Shorthands) syntax (e.g. `:href`or `@click`).
