Question

I am developing a small app in Node.js. I am just using Node.js for input and output. The actual website is just running through nginx. The website has a Websocket connection with node.js and is primarily used for db manipulations.

One of the things I am trying to do is get node to send small pieces of html along with the data from the database. I tried the following code.

simplified:

    connection.on('message', function(message) {
        fs.readFile(__dirname + '/views/user.html', function(err, html){

            if(err){
                console.log(err);
            }else{
                connection.sendUTF( JSON.stringify({
                    content: html,
                    data: {}
                }));
            }
        });
    }
});

When I console.log(html) on the server or in the client I only get numbers back.

Anyone know what could be wrong.

NOTE: I really want to stay away from stuff like socket.io, express, etc. Just keeping it as simple as possible and no fallbacks are needed.

If you don’t specify an encoding for fs.readFile, you will retrieve the raw buffer instead of the expected file contents.

Try calling it this way:

fs.readFile(__dirname + '/views/user.html', 'utf8', function(err, html){
