Writing files in Node.js

Question

I\'ve been trying to find a way to write to a file when using Node.js, but with no success. How can I do that?

Answer 1

 var fs = require('fs');
 fs.writeFile(path + "\\message.txt", "Hello", function(err){
 if (err) throw err;
  console.log("success");
}); 

For example : read file and write to another file :

  var fs = require('fs');
    var path = process.cwd();
    fs.readFile(path+"\\from.txt",function(err,data)
                {
                    if(err)
                        console.log(err)
                    else
                        {
                            fs.writeFile(path+"\\to.text",function(erro){
                                if(erro)
                                    console.log("error : "+erro);
                                else
                                    console.log("success");
                            });
                        }
                });
