Socket using the AppRtc WebSocket server to exchange messages between two peers. This socket is developed to exchange lightweight signaling messages, not for transmitting (large) binaries.

• supports text message exchange between two peers identified by a unique key
• offers callback and promise based API
• can be browserified

npm install apprtc-socket

const socket = require('apprtc-socket');

const myId = 'foo'; // replace with unique key
const peerId = 'bar'; // replace with unique key

const mySocket = socket(myId, peerId);
// socket is connected and ready to use
mySocket.on('ready', () => {
  // send text message to peer
  mySocket.send('test message');
  // close socket
  mySocket.close();
});
mySocket.on('message', (message) => {
  // incoming text message
});
mySocket.on('close', () => {
  // socket is closed
});
mySocket.on('error', (error) => {
  // ooops
});

// activate the connection
mySocket.connect();

const socket = require('apprtc-socket');

const myId = 'foo'; // replace with unique key
const peerId = 'bar'; // replace with unique key

const mySocket = socket(myId, peerId);
mySocket.on('message', (message) => {
  // incoming text message
});
mySocket.on('error', (error) => {
  // ooops
});

// activate the connection
mySocket.connectP()
  // socket is connected and ready to use
  .then(() => {
    // send text message to peer
    mySocket.send('test message');
    // close socket
    return mySocket.closeP();
  })
  .then(() => {
    // socket is closed
  })
  .catch((error) => {
    // ooops
  });

Create a new AppRtcSocket connection. Both interacting peers must be identified by a unique key.

Connect to the AppRtc WebSocket server and register a connection. The id of the AppRtc room that both peers use to exchange messages is a commutative hash calculated from both peers' unique keys. This function fires a ready event once the registration succeeds.

Connect to the AppRtc WebSocket server and register a connection. Instead of firing a ready event, this function returns a promise that gets fulfilled once the registration succeeds.

Send text data to the connected peer. data should be of type String, other data types can be transformed into a String with JSON.stringify.

Close a connection. Fires a close event once complete.

Close a connection. Instead of firing a close event, this function returns a promise that gets fulfilled once the connection has closed.

Fired when the socket is ready to use.

Received a message from the AppRtc server. message is always a String.

Fired when the connection has closed.

Fired when a fatal error occurs.
