Express 4.x compression

Question

I have tested my local web server with Google's PageSpeed chrome extension. One of the results was that my web server doesn't have compression enabled. I am using node js on the backend with express 4.x. I googled a bit to find a solution to compress data and I found https://github.com/expressjs/compression a middleware for express. I tried to use it like this:

    var app                 = express();
    var compression         = require('compression');
    var server              = http.createServer(app);
    server.listen(CONFIG.PORT);
    app.use(compression());

Even though I did this pageSpeed is still recommending to compress data. What am I doing wrong?

What data did it recommend to compress? `compression` middleware only compresses response — Vsevolod Goloviznin, Feb 09 '15 at 09:09
I have made some changes and I am putting compression as the first middleware to use and it is compressing all the data sent by the server for example /api/mongoModel but it is not compressing .js, .css and .html files. — exilonX, Feb 09 '15 at 09:14

app.use(compression());
app.use(express.static(__dirname+'/public'));

Put JS, CSS, HTML files below the public directory and they will be compressed.

//use compression to speedup page load

app.use(compression());

app.use('app', function (req, res, next) {});
