write-file-to-socket

Write a file to & read a file from a socket.

npm install write-file-to-socket

or install globally to use the CLI:

npm install -g write-file-to-socket

Example

server.js:

var WFTS = require('write-file-to-socket')
var wfts = new WFTS({
  port: 4801,
  file: 'hello-world.txt'
})
wfts.serve()

receiver.js

var WFTS = require('write-file-to-socket')
var wfts = new WFTS({
  port: 4801,
  file: 'hola-mundo.txt',
})
wfts.pull()

Usage

There are lots of ways to send files to other people. But occasionally there might be a time that you are at a computer wanting to share a file with another person at a computer next to you. And maybe the usual methods for sending a file just aren't cutting it: too big to send via Slack, pain to log into Dropbox, AirDrop isn't finding you (??!). All you wanna do is pipe a file over to them a la netcat:

$ cat my-file.txt | nc -l 4000

which is probably what you should end up using. But now can also do with this module. :raised_hands:

methods

var wfts = require('write-file-to-socket')(opts)

options are port, host, file. Only required is file for serving. Defaults to take file from the current working directory, but accept a path too.

var opts = { port: 4000, file: '/path/to/a/file.txt'}
wfts.serve()
// serving that file at localhost:4000

wfts.serve()

serves a file from the port as given in opts.

wfts.pull([cb])

reads a file from the port and host given opts and writes it to the file path given. If no file path is set in opts then writes a file called wfts-file to the current working directory. Provides an optional callback that is run after the file transfer is complete.

wfts.pull(function () { console.log('just wrote a file!') })

CLI

$ wfts --help
usage: wfts <command> [file] [-p PORT] [-h host] [--help]

example:

Serve a file on default host and port (localhost:4000)

    $ wfts serve my-file.txt

Receive a file on host 10.1.2.3 and port 3333 and save it to the
current working directory as "my-received-file.txt".

    $ wfts pull my-received-file.txt -h 10.1.2.3 -p 3333
