Since Twitter Bootstrap 2 is out, I wanted to integrate that into my Node.js project. Unfortunately, there's something wrong with the less compiler and I can't get it to work. I put all files into the public folder and set up a new project with express -c less newproj. and added the lines for less

less = require('less');
app.use(express.compiler({ src: __dirname + '/public', enable: ['less'] }));

All Node tells me is:

Express server listening on port 3000 in development mode
undefined

On the client side I get a 500 (Internal Server Error) for the bootstrap.css file, which should be compiled by lessc.

lessc bootstrap.less

Works fine.

Anybody knows how to solve the issue?

For posterity, this has changed a lot in recent Express:

app.use(require('less-middleware')({ src: __dirname + '/public' }));
app.use(express.static(path.join(__dirname, 'public')));

// This is just boilerplate you should already have
app.use(express.bodyParser());
app.use(express.methodOverride());
app.use(app.router);
