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

I liked Index of ./articles/file-system.

It worked for me.

See also How do I write files in node.js?.

fs = require('fs');
fs.writeFile('helloworld.txt', 'Hello World!', function (err) {
    if (err) 
        return console.log(err);
    console.log('Wrote Hello World in file helloworld.txt, just check it');
});

Contents of helloworld.txt:

Hello World!

Update:
As in Linux node write in current directory , it seems in some others don't, so I add this comment just in case :
Using this ROOT_APP_PATH = fs.realpathSync('.'); console.log(ROOT_APP_PATH); to get where the file is written.
