# Netflux
![Netflux logo][logo]
Isomorphic Javascript **peer to peer** transport API for client and server.
Secure and fault tolerant full mesh peer to peer network based on **RTCDataChannel** and **WebSocket**.
Send/receive **String** and **Uint8Array** data types.

![Netflux example][netflux_example]
## Features
- Peer to peer full mesh network tolerant to connection failures.
- Same API for clients (Chrome, Firefox) and servers (NodeJS).
- Send private or broadcast messages with [String][string], [Uint8Array][uint8array] data types.
- Send large amounts of data (over the limit of ~16kb used in RTCDataChannel).
- Automatic rejoin the group when connection lost.
- Hide the connection nature ( [WebSocket][websocket] or [RTCDataChannel][rtcdatachannel]) from API consumer.
- All connections are encrypted.
- Full control over WebRTC servers: Signaling, STUN and TURN.
- Deploy your own Signaling server ([Sigver][sigver]) or use the one provided by default.
- Configure STUN and TURN servers.
- Small Signaling server payload.
- Signaling server is only used to establish connection between two peers, no user data is passing through it.
- TypeScript declaration files are included.
- Simple and familiar API usage.
- Multiple bundles to suit your workflow:
- For NodeJS
- `dist/netflux.node.es5.cjs.js` commonjs format, es5 code (see _package.json#main_).
- `dist/netflux.node.es5.esm.js` ES module format, es5 code (see _package.json#module_).
- For browsers
- `dist/netflux.browser.es5.umd.js` UMD format, es5 code
- `dist/netflux.browser.es5.esm.js` ES module format, es5 code (see _package.json#browser_).
- `dist/netflux.browser.es2015.esm.js` ES module format, es2015 code (see _package.json#es2015_).
- `dist/netflux.browser.esnext.esm.js` ES module format, esnext code (see _package.json#esnext_).
## Install
```shell
npm install netflux
```
3 peer dependencies to be installed in some cases:
- `rxjs` is necessary for both NodeJS and browsers if you want to take advantage of EcmaScript modules, tree-shaking etc. Otherwise it is already included into `dist/netflux.browser.es5.umd.js` and `dist/netflux.node.es5.cjs.js` bundles.
```shell
npm install rxjs
```
- `uws` and `text-encoding` if you target NodeJS (developing a bot):
```shell
npm install uws text-encoding
```
**Why peer dependencies?**
- Reduce the installation size by omitting unused dependencies.
- Take advantage of new standards and techniques: EcmaScript modules, bundle tools like Webpack, Rollup etc.
## Usage
Here is a basic usage example for client and server (checkout the [documenation](https://coast-team.github.io/netflux) for more details).
> Bot server is not mandatory. The group may completely be composed of clients only, as well as be composed of servers only or may also be mixed.
### Client example
```javascript
import { WebGroup, WebGroupState } from 'netflux'
// Create instance and set callbacks
const wg = new WebGroup()
wg.onMemberJoin = (id) => {
console.log(`Member ${id} has joined. Current members list is: `, wg.members)
// Say hello to the new peer
wg.sendTo(id, 'Hello, my name is Bob')
}
wg.onMemberLeave = (id) => {
console.log(`Member ${id} has left. Remained members are: `, wg.members)
}
wg.onMessage = (id, data) => {
console.log(`Message from ${id} group member`, data)
}
wg.onStateChange = (state) => {
console.log('The new Group state is ', state)
switch (state) {
case WebGroupState.JOINING:
// Do something
break
case WebGroupState.JOINED:
// Do something... for example invite a bot...
wg.invite('BOT_SERVER_WEB_SOCKET_URL')
// Or send message to all peers
wg.send('Hello everybody. I have just joined the group.')
break
case WebGroupState.LEFT:
// wg.key === ''
// wg.id === 0
// wg.myId === 0
// wg.members === []
// the current wg object is at the same state as if it was instantiated via new WebGroup(...), hence
// it can be reused to join another group for example.
// Do something...
break
}
}
// Join the group
wg.join('MY_UNIQUE_KEY_FOR_THE_GROUP')
```
### Bot example
```javascript
import { Bot, WebGroupState } from 'netflux'
const http = require('http') // https is also possible
const server = http.createServer()
const bot = new Bot({
server: server,
webGroupOptions: {
// Any WebGroup options like for a client
},
})
bot.onWebGroup = (wg) => {
console.log('The current state is JOINING: ', wg.state === WebGroupState.JOINING)
// New instance of a WebGroup (Someone has invited this bot).
// See example above for client as it is the same API.
}
server.listen(BOT_PORT, _BOT_HOST)
// A client may invite this bot with the following URL: 'ws://BOT_HOST:BOT_PORT'
```

Netflux used as a transport layer for Multi User Text Editor ([MUTE repo](https://github.com/coast-team/mute)) developed by our team. The demo version is available on: .
