A command line utility that allows read/write (i.e copy/paste) access to the system clipboard.
npm install copy-pasteA command line utility that allows read/write (i.e copy/paste) access to the system clipboard. It does this by wrapping pbcopy/pbpaste (for OSX), xclip (for Linux, FreeBSD, and OpenBSD), and clip (for Windows). Currently works with node.js v0.8+.
When require("copy-paste") is executed, an object with the following properties is returned:
- copy(text[, callback]): asynchronously replaces the current contents of the clip board with text. Takes either a string, array, object, or readable stream. Returns the same value passed in. Optional callback will fire when the copy operation is complete.
- copy.json(obj[, callback]): asynchronously replaces the current contents of the clip board with the JSON string of obj. Returns the same value passed in. Optional callback will fire when the copy operation is complete.
- paste([callback]): if no callback is provided, paste synchronously returns the current contents of the system clip board. Otherwise, the contents of the system clip board are passed to the callback as the second parameter. The first one being a potential error.
- require("copy-paste").global(): adds copy and paste to the global namespace. Returns an object with copy and paste as properties.
Example usage:
``js
const { copy, paste } = require("copy-paste");
copy("some text", (err, text) => {
// "some text" is in your clipboard
});
paste((err, text) => {
// complete...
});
const text = paste(); // Synchronous paste
copy({ hello: "world" }) // Asynchronous copy
`
For modern JavaScript applications, you can use the promise-based interface by requiring the promises submodule:
`javascript`
const clipboard = require('copy-paste/promises');
The promise-based API provides the following methods:
- copy(text): Returns a promise that resolves with the copied text when the operation is completecopy.json(obj)
- : Returns a promise that resolves with the copied JSON string when the operation is completepaste()
- : Returns a promise that resolves with the clipboard contents when the operation is complete
Example usage with async/await:
`javascript
const { copy, paste } = require('copy-paste/promises');
// Copy text
await copy('Hello World');
// Copy JSON
await copy.json({ hello: 'world' });
// Paste text
const text = await paste();
`
The easiest way to get node-copy-paste is with npm:
npm install copy-paste
Alternatively you can clone this git repository:
git clone git://github.com/xavi-/node-copy-paste.git
I'm hoping to add various fallbacks for instances when xclip or clip` is not avaiable (see experimental-fallbacks branch). Also this library needs to be more thoroughly tested on windows.
