Express LESS

On-the-fly LESS-to-CSS conversion middleware.

For more information on LESS visit lesscss.org.

Installation

$ npm install express-less

Usage

var express = require('express'),
    expressLess = require('express-less');

var app = express();
app.use('/less-css', expressLess(__dirname + '/less'));

Now request to /less-css/styles.css will return rendered contents of ./less/styles.less. Note the change of file extension from .less to .css.

Additionally, you can ask LESS to compress the result:

app.use('/less-css', expressLess(__dirname + '/less', { compress: true }));

You can enable the cache system to improve performance:

app.use('/less-css', expressLess(__dirname + '/less', { cache: true }));

For detail information on LESS errors use the debug option, e.g.

// Enable error reporting permanently
app.use('/less-css', expressLess(__dirname + '/less', { debug: true }));

// or only for development environment
app.use('/less-css', expressLess(__dirname + '/less', {
    debug: app.get('env') == 'development'
}));

Tests

$ npm test
