create a file through appendfile vs writefile code example
Example 1: How to append to a file in Node?
// Asynchronously:
const fs = require('fs');
fs.appendFile('message.txt', 'data to append', function (err) {
if (err) throw err;
console.log('Saved!');
});
// Synchronously:
const fs = require('fs');
fs.appendFileSync('message.txt', 'data to append');
Example 2: writefile in node js
// append_file.js
const fs = require('fs');
// add a line to a lyric file, using appendFile
fs.appendFile('empirestate.txt', '\nRight there up on Broadway', (err) => {
if (err) throw err;
console.log('The lyrics were updated!');
});
