// fs_write.js const fs = require('fs'); // specify the path to the file, and create a buffer with characters we want to write let path = 'ghetto_gospel.txt'; let buffer = new Buffer('Those who wish to follow me\nI welcome with my hands\nAnd the red sun sinks at last'); // open the file in writing mode, adding a callback function where we do the actual writing fs.open(path, 'w', function(err, fd) { if (err) { throw 'could not open file: ' + err; } // write the contents of the buffer, from position 0 to the end, to the file descriptor returned in opening our file fs.write(fd, buffer, 0, buffer.length, null, function(err) { if (err) throw 'error writing file: ' + err; fs.close(fd, function() { console.log('wrote the file successfully'); }); }); });

// write_stream.js const fs = require('fs'); let writeStream = fs.createWriteStream('secret.txt'); // write some data with a base64 encoding writeStream.write('aef35ghhjdk74hja83ksnfjk888sfsf', 'base64'); // the finish event is emitted when all data has been flushed from the stream writeStream.on('finish', () => { console.log('wrote all data to file'); }); // close the stream writeStream.end();

var fs = require('fs'); var txt = '\n' + tkn_psid_id + ':' + assetUrl; var folderName = '/duplicates/bugging/videobug/' + tkn_psid_id + '.txt'; fs.appendFile(folderName, txt, function (err) { if (err) { console.log('Append Error'); } else { console.log('DuplicateFolder' + folder); } });
