Render markdown in node/express with variables

gistfile1.js

// You need to install 'node-markdown': `npm install node-markdown`
// In your app.configure section add 'md' to 'view options' ie:

app.set('view options', { layout: 'layouts/index', md: require("node-markdown").Markdown })

// Then in your jade template you can use:

div!=md(text)

This was driving me crazy and I couldn't find anything on the net about how to do this, hopefully this will help someone!

Apparently the :markdown filter does not support variables as it's rendered at compile time
