Writing files in Node.js

There are a lot of details in the File System API. The most common way is:

const fs = require('fs');



fs.writeFile("/tmp/test", "Hey there!", function(err) {

    if(err) {

        return console.log(err);

    }

    console.log("The file was saved!");

}); 



// Or

fs.writeFileSync('/tmp/test-sync', 'Hey there!');

const fs = require('fs');

fs.writeFile("/tmp/test", "Hey there!", function(err) {
if(err) {
return console.log(err);
}
console.log("The file was saved!");
});
here we are importing fs module by using rquire to write and read fle data

var path = 'public/uploads/file.txt',
buffer = new Buffer("some content\n");

fs.open(path, 'w', function(err, fd) {
if (err) {
throw 'error opening file: ' + err;
}

fs.write(fd, buffer, 0, buffer.length, null, function(err) {
if (err) throw 'error writing file: ' + err;
fs.close(fd, function() {
console.log('file written');
})
});
});
