react-copy-to-clipboard

Copy to clipboard React component

Based on copy-to-clipboard

Would try to use execCommand with fallback to IE specific clipboardData interface and finally, fallback to simple prompt with proper text content & 'Copy to clipboard: Ctrl+C, Enter'

Installation

NPM

npm install --save react react-copy-to-clipboard

Don't forget to manually install peer dependencies (react) if you use npm@3.
