How to render html page in node.js using http responce object?

Question

this is my js file code:

fs.readFile(__dirname+'/product_list.html',function(error,productForm){
    if(error){
        response.write("error in getting file"+error);
    }else{
            connection.query("select * from products",function(err,result){
            if(err){
                console.log("In funciton errr");
            }else{
                response.writeHead(200, "OK", {'Content-Type': 'text/html'});
                response.write(productForm,{result:result});

                }
        });
    response.end();
    }
});

i want result on product_list.html page.....

you can use a template engine as ejs or other one it will be faster in this way and cleaner — Alexandru Olaru

The problem you have is that connection.query is asynchronous, you should call response.end() within the callback function of connection.query

fs.readFile(__dirname+'/product_list.html',function(error,productForm){
    if(error){
        response.write("error in getting file"+error);
        response.end(); //finish here
    }else{
        connection.query("select * from products",function(err,result){
            if(err){
                console.log("In funciton errr");
                response.end(); //finish here
            }else{
                response.writeHead(200, "OK", {'Content-Type': 'text/html'});
                response.write(productForm,{result:result});
                response.end(); //finish here
            }
        });
    }
});

what is productForm and {result: result}? are you using any template engine? then it should be response.render(productForm, {result: result})
