I need to read a file and replace some texts in that file with dynamic content.when i tried string.replace it is not working for the data that i read from the file.But for the string it is working.I am using node.js and express.

fs.readFile('test.html', function read(err, data) {

    if (err) {

                console.log(err);

    }

    else {

        var msg = data.toString();

        msg.replace(%name%, myname);

        msg.replace(/%email%/gi, '[email protected]');



        temp = Hello %NAME%, would you like some %DRINK%?;

        temp = temp.replace(/%NAME%/gi,Myname);

        temp = temp.replace(%DRINK%,tea);

        console.log(temp: +temp);

        console.log(msg: +msg);

    }

});

Output:

temp: Hello Myname, would you like some tea?

msg: Hello %NAME%, would you like some %DRINK%?
