Very simple way to make a command line markdown renderer using Node.js and Pagedown. Only accepts streams in, not arguments, not files...Handy for langauges with a Popen3 library (write to the stdin, read from the stdout). Needed this so I could use the same library server side (rails) as client side. And because I was too lazy to try and figure…

render_markdown.js

function createMarkdown() {
  var pagedown = require('pagedown');
  var converter = new pagedown.getSanitizingConverter();
  process.stdout.write(converter.makeHtml(lines));
}
process.stdin.resume();
process.stdin.setEncoding('utf8');

var lines = "";
process.stdin.on('data', function(chunk) {
  lines += chunk;
});
process.stdin.on('end', createMarkdown);
