Copy to clipboard 

Simple module exposing copy function that will try to use execCommand with fallback to IE-specific clipboardData interface and finally, resort to usual prompt with proper text content and message.

> If you are building using Electron, use their API.

Example

``js
import copy from 'copy-to-clipboard';

copy('Text');

// Copy with options
copy('Text', {
debug: true,
message: 'Press #{key} to copy',
});
`

API

copy(text: string, options: object): boolean — tries to copy text to clipboard. Returns true if no additional keystrokes were required from user (so, execCommand, IE's clipboardData worked) or false.

|Value |Default |Notes|
|------|--------|-----|
|options.debug |false| Boolean. Optional. Enable output to console. |
|options.message|Copy to clipboard: #{key}, Enter| String. Optional. Prompt message. * |
|options.format|"text/html"| String. Optional. Set the MIME type of what you want to copy as. Use text/html to copy as HTML, text/plain to avoid inherited styles showing when pasted into rich text editor. |
|options.onCopy|null| function onCopy(clipboardData: object): void. Optional. Receives the clipboardData element for adding custom behavior such as additional formats |

* all occurrences of #{key} are replaced with ⌘+C for macOS/iOS users, and Ctrl+C otherwise.

Browser support

Works everywhere where prompt* is available. Works best (i.e. without additional keystrokes) in Chrome, FF, Safari 10+, and, supposedly, IE/Edge.

Note: does not work on some older iOS devices.
* – even though Safari 8 has prompt, you cannot specify prefilled content for prompt modal – thus it doesn't work as expected.
