    text
    copied!<p><code>Middleware in my Node.js</code></p> <pre><code> functions.editorPreview = function (req, res) { var data = req.body.text; fs.writeFile(__dirname + '/message.txt', data, function (err) { if (err) throw err; child = exec('kramdown ' + __dirname + '/message.txt', function (error, stdout, stderr) { if (error) { return res.json(500, error.message); } return res.json(200, { text: stdout }); }); }); }; </code></pre> <p><code>$.post method in index.html</code></p> <pre><code>$(function() { $('#kramdown-input').keyup(function() { $.post('/editor/preview', { text: $(this).val() }, function(data) { $('#output').html(data.text); $('pre code').each(function(i, e) { hljs.highlightBlock(e) }); MathJax.Hub.Queue(['Typeset', MathJax.Hub]); }); }); $('#kramdown-input').trigger('keyup'); }); </code></pre> <p>So I'm writing my open-source CMS in Node.js called <a href="https://github.com/alicoding/spectrum" rel="nofollow">Spectrum</a>, and I was looking for a good Markdown editor and none of them that really impress me that written in JavaScript.</p> <p>I have come across this one Kramdown and I really liked it.</p> <p>I have zero knowledge about <code>Ruby</code>, but I got it to the point where it is now working with my CMS, but one problem that I'm concern here.</p> <p>The code above I have make Kramdown to interact on the preview panel, but is this really efficient? </p> <p>Because this is like we are sending a GET/POST request to the server every single time the user time a character. </p> <p>I was trying to check if there is a better way to parse the data without having to write the file and then execute <code>Kramdown</code> to parse the file then sending data back. </p> <p>Is there a better way to do this? I don't really feel good with my solution here :(</p>
