Right after creating your Derby app, add:
// Add Stylus support
app.serverUse(module, 'derby-stylus');Make sure this is before any calls to app.loadStyles().
After that you can use *.styl files instead of *.css
index.js
var derby = require('derby');
var app = module.exports = derby.createApp('example', __filename);
// Add Stylus support (before loadStyles)
app.serverUse(module, 'derby-stylus');
app.loadViews (__dirname);
app.loadStyles(__dirname);
app.get('/', function(page, model) {
page.render();
});index.html
