clipboard

Perform copy and paste operations on the system clipboard.

Process: Main, Renderer

The following example shows how to write a string to the clipboard:

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:

const {clipboard} = require('electron')
clipboard.writeText('Example String', 'selection')
console.log(clipboard.readText('selection'))
