WebRTC Simple File Transfer

A simple library to send & receive files over WebRTC data channels. All you need to pass is a simple-peer object, the file, and an ID!

Features

• Pause/Resume file transfers
• No file size limit
• Independent, just pass a simple-peer object
• Multiple file transfers at the same time using the same simple-peer object

Examples

Apps Made With SPF

• WebDrop - A web app to share files and messages across all your devices. [Try It Here!]()

Simple Example

Open this webpage in two separate browser windows. This simple example is based on the example shown in simple-peer README

Sender :

import SimplePeerFiles from 'simple-peer-files'
const spf = new SimplePeerFiles()

function readyToSend () {
  // peer is the SimplePeer object connection to receiver
  spf.send(peer, 'myFileID', file).then(transfer => {
    transfer.on('progress', sentBytes => {
      console.log(sentBytes)
    })
    transfer.start()
  })
}

Receiver :

import SimplePeerFiles from 'simple-peer-files'
const spf = new SimplePeerFiles()

// peer is the SimplePeer object connection to sender
spf.receive(peer, 'myFileID').then(transfer => {
  transfer.on('progress', sentBytes => {
    console.log(sentBytes)
  })

  // Call readyToSend() in the sender side
  peer.send('heySenderYouCanSendNow')
})

You have to call spf.receive() in receiver before you call spf.send() in sender. This is to prepare the receiver to accept file before sending starts. This also allows to implement a functionality for the receiver to accept or reject the file.
