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

Synchronous Write

fs.writeFileSync(file, data[, options])

fs = require('fs');

fs.writeFileSync("foo.txt", "bar");

Asynchronous Write

fs.writeFile(file, data[, options], callback)

fs = require('fs');

fs.writeFile('foo.txt', 'bar', (err) => { if (err) throw err; });

Where

file  |  |  |  filename or file descriptor
data  |  | 
options
