win-clipboard
An experimental Node.js module that provides you a full control over host clipboard in Windows environment.
Installation
If you haven't ever messed up with C++ addons, you'll have most likely to install windows-build-tools
. It takes a fair amount of time to complete, but simplifies the installation by a lot.
npm install --global --production windows-build-tools
Once you have the above, it's as simple as:
npm install --save win-clipboard
Usage
const clipboard = require( 'win-clipboard' );
clipboard.getText(); // Returns unicode format as a string.
clipboard.getHTML(); // Returns HTML as a string.
clipboard.getData( 'HTML Format' ); // Returns raw content of a "HTML Format".
clipboard.setText( '🙀🙊' ); // Sets some fancy emoji in your unicode format.
clipboard.getFormats(); // Lists formats in the clipboard.

Why?
I needed to put some fancy stuff into a clipboard, and I was surprised that there's no good library for managing the clipboard.
What I needed was an ability to set HTML / RTF / plain text together, which was nowhere to be found.
Other requirement that I had in other side project, was retrieve all the formats in clipboard, for a further inspection.
All the implementation allowed just for setting a plaintext - it was due to the fact that it was based on clip
bin.
How?
I implemented it using a Node.js C++ addon, which uses WinAPI.
The implementation turned out to be extremely easy, while having access to the WinAPI it gives all the power in the world to work with the clipboard.
