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.
