# clipboard
> Perform copy and paste operations on the system clipboard.
The following example shows how to write a string to the clipboard:
```javascript
const {clipboard} = require('electron')
clipboard.writeText('Example String')
```
On X Window systems, there is also a selection clipboard. To manipulate it
you need to pass `selection` to each method:
```javascript
const {clipboard} = require('electron')
clipboard.writeText('Example String', 'selection')
console.log(clipboard.readText('selection'))
```
## Methods
The `clipboard` module has the following methods:
**Note:** Experimental APIs are marked as such and could be removed in future.
### `clipboard.readText([type])`
* `type` String (optional)
Returns `String` - The content in the clipboard as plain text.
### `clipboard.writeText(text[, type])`
* `text` String
* `type` String (optional)
Writes the `text` into the clipboard as plain text.
### `clipboard.readHTML([type])`
* `type` String (optional)
Returns `String` - The content in the clipboard as markup.
### `clipboard.writeHTML(markup[, type])`
* `markup` String
* `type` String (optional)
Writes `markup` to the clipboard.
### `clipboard.readImage([type])`
* `type` String (optional)
Returns `NativeImage` - The content in the clipboard as a [NativeImage](native-image.md).
### `clipboard.writeImage(image[, type])`
* `image` [NativeImage](native-image.md)
* `type` String (optional)
Writes `image` to the clipboard.
### `clipboard.readRTF([type])`
* `type` String (optional)
Returns `String` - The content in the clipboard as RTF.
### `clipboard.writeRTF(text[, type])`
* `text` String
* `type` String (optional)
Writes the `text` into the clipboard in RTF.
### `clipboard.readBookmark()` _macOS_ _Windows_
Returns `Object`:
* `title` String
* `url` String
Returns an Object containing `title` and `url` keys representing the bookmark in
the clipboard. The `title` and `url` values will be empty strings when the
bookmark is unavailable.
### `clipboard.writeBookmark(title, url[, type])` _macOS_ _Windows_
* `title` String
* `url` String
* `type` String (optional)
Writes the `title` and `url` into the clipboard as a bookmark.
**Note:** Most apps on Windows don't support pasting bookmarks into them so
you can use `clipboard.write` to write both a bookmark and fallback text to the
clipboard.
```js
clipboard.write({
text: 'http://electron.atom.io',
bookmark: 'Electron Homepage'
})
```
### `clipboard.clear([type])`
* `type` String (optional)
Clears the clipboard content.

### `clipboard.has(data[, type])` _Experimental_
* `data` String
* `type` String (optional)
Returns `Boolean` - Whether the clipboard supports the format of specified `data`.
```javascript
const {clipboard} = require('electron')
console.log(clipboard.has('<p>selection</p>'))
```
### `clipboard.read(data[, type])` _Experimental_
* `data` String
* `type` String (optional)
Returns `String` - Reads `data` from the clipboard.
### `clipboard.write(data[, type])`
* `data` Object
* `text` String
* `html` String
* `image` [NativeImage](native-image.md)
