We need a better Markdown previewer.
pen is a Markdown previewer written in JavaScript, aiming to just work.
Using pen is super simple, we don't need to install any special editor or
launch any GUI application. pen is just a tidy command-line tool. You can use
your favourite editor and browser. No manual refresh is even needed.
Also, the previewer renders the content using React. It means that it will not re-render entire DOM when the document is updated. This is a huge advantage because images or other media won't be reloaded for the DOM update.
I personally love to use pen, and I hope you love it too. ✒️
Demo
Here is a short demo showing how awesome pen is.
The following demo shows pen incrementally updates only modified part using
React and
its Virtual DOM.
Requirement
pen uses Node.js >= 4.0. It may not work
on earlier versions.
Install
Using npm:
npm i -g yoginth-pen
You can try using pen with npx:
npx -p yoginth-pen pen
Usage
To use pen, simply run the pen command.
pen README.md
The command above will launch a pen server and open the file in your default
browser. The server will listen to a 6060 port by default. To be honest, you
don't even need to launch it with a filename. You can manually open
http://localhost:6060/README.md, or any other files in the same directory.
To stop the server, enter ^C.
For the further details of the pen command, please enter pen -h or pen --help.
