# Using plugins
## List of Plugins
### Full text search
By default, the hyperlink on the current page is recognized and the content is saved in `localStorage`. You can also specify the path to the files.
```html
<script>
window.$docsify = {
search: 'auto', // default
search : [
'/', // => /README.md
'/guide', // => /guide.md
'/get-started', // => /get-started.md
'/zh-cn/', // => /zh-cn/README.md
],
// 完整配置参数
search: {
maxAge: 86400000, // Expiration time, the default one day
paths: [], // or 'auto'
placeholder: 'Type to search'
}
}
</script>
<script src="//unpkg.com/docsify"></script>
<script src="//unpkg.com/docsify/lib/plugins/search.js"></script>
```
### Google Analytics
Install the plugin and configure the track id.
```html
<script>
window.$docsify = {
ga: 'UA-XXXXX-Y'
}
</script>
<script src="//unpkg.com/docsify"></script>
<script src="//unpkg.com/docsify/lib/plugins/ga.js"></script>
```
Configure by `data-ga`.
```html
<script src="//unpkg.com/docsify" data-ga="UA-XXXXX-Y"></script>
<script src="//unpkg.com/docsify/lib/plugins/ga.js"></script>
```
## Write a plugin
A plugin is simply a function that takes `hook` as arguments.
The hook supports handling asynchronous tasks.
#### Full configuration
```js
window.$docsify = {
plugins: [
function (hook) {
hook.init(function() {
// Called when the script starts running, only trigger once, no arguments,
})
hook.beforeEach(function(content) {
// Invoked each time before parsing the Markdown file.
// ...
return content
})
hook.afterEach(function(html, next) {
// Invoked each time after the Markdown file is parsed.
// beforeEach and afterEach support asynchronous。
// ...
// call `next(html)` when task is done.
next(html)
})
hook.doneEach(function() {
// Invoked each time after the data is fully loaded, no arguments,
// ...
})
hook.ready(function() {
// Called after initialization is complete. Only trigger once, no arguments.
})
}
]
}
```
!> You can get internal methods through `window.Docsify.utils`.
#### Example
Add footer component in each pages.
```js
window.$docsify = {
plugins: [
function (hook) {
var footer = [
'<hr/>',
'<footer>',
'<span><a href="https://github.com/QingWei-Li">cinwell</a> &copy;2017.</span>',
'<span>Proudly published with <a href="https://github.com/QingWei-Li/docsify" target="_blank">docsify</a>.</span>',
'</footer>'
].join('')
hook.afterEach(function (html) {
return html + footer
})
}
]
}
```
