We need a better Markdown previewer.
There are literally tons of Markdown previewers out there. I love some of them, I even made one of them. Nevertheless, we always need a better one, don't we?
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.
