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

Here we use w+ for read/write both actions and if the file path is not found the it would be created automatically.

fs.open(path, 'w+', function(err, data) {
    if (err) {
        console.log("ERROR !! " + err);
    } else {
        fs.write(data, 'content', 0, 'content length', null, function(err) {
            if (err)
                console.log("ERROR !! " + err);
            fs.close(data, function() {
                console.log('written success');
            })
        });
    }
});

Content means what you have to write to the file and its length, 'content.length'.
