nodejs send html file to client

Try your code like this:

var app = express();
app.get('/test', function(req, res) {
    res.sendFile('views/test.html', {root: __dirname })
});

1. Use res.sendFile instead of reading the file manually so express can handle setting the content-type properly for you.

2. You don’t need the app.engine line, as that is handled internally by express.
