clipboard

Perform copy and paste operations on the system clipboard.

Process: Main, Renderer

On Linux, 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'))

clipboard.readBookmark() macOS Windows

Returns Object:

console.log(buffer.equals(out))
// true
