How to write 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?

Hello @kartik,

Currently there are three ways to write a file:

1. fs.write(fd, buffer, offset, length, position, callback)

   You need to wait for the callback to ensure that the buffer is written to disk. It's not buffered.

2. fs.writeFile(filename, data, [encoding], callback)

   All data must be stored at the same time; you cannot perform sequential writes.

3. fs.createWriteStream(path, [options])

   Creates a WriteStream, which is convenient because you don't need to wait for a callback. But again, it's not buffered.

Hope it helps!!

Thank You!!
