AnySocket

An abstract networking layer over multiple transports, client/server agnostic with support for E2EE

Important

This is a work in progress and API is subject to change.

Features

Client / Server agnostic
Support for request/reply
Custom AUTH method
E2EE between peers with forward secrecy
RPC support
NTP Sync between peers support
P2P using a proxy server (with support for direct E2EE between peers)
Binary support (see: AnySocket.Packer)
Browser support - 31kb footprint (see: /dist/anysocket.browser.js)
Multiple transports *(implemented atm: ws/wss, http/https)
All peers have a UUIDv4 associated
Disconnect detection using a heartbeat
Not Battle Tested ...yet

** http transport is experimental

Info: Binary RPC arguments and responses are auto packed/unpacked (AnySocket.Packer.pack/AnySocket.Packer.unpack).

Benchmarks

Installation

npm install --save anysocket

<script src="/dist/anysocket.browser.js"></script>

or (if using AnySocketHTTP)

<script src="@anysocket"></script>

How to use

The following example starts a websocket server on port 3000.

const AnySocket = require("anysocket");
const server = new AnySocket();
const PORT = 3000;
server.listen("ws", PORT)
    .then(() => {
        console.log("Listening on port:", PORT);
    })
    .catch((err) => {
        console.error("Failed to start server:", err);
    });
server.on("connected", async (peer) => {
    console.log("Connected", peer.id);
    console.log(await peer.getSyncedTime()) // { time: 1674671482107, rtt: 2, offset: 0 }
    peer.send({
        hello: "world"
    });
});
server.on("message", (packet) => {
    console.log("From:", packet.peer.id, "Message:", packet.msg);
});
server.on("disconnected", (peer, reason) => {
    console.log("Disconnected", peer.id, "Reason:", reason);
});

The following example connects to a websocket on port 3000

const AnySocket = require("anysocket");
const client = new AnySocket();
const PORT = 3000;
client.connect("ws", "127.0.0.1", PORT)
    .then(() => {
        console.log("Connected to server");
    })
    .catch((err) => {
        console.error("Failed to connect to server:", err);
    });

// after negotiating the AUTH packet, it will trigger the connect event
client.on("connected", async (peer) => {
    console.log("Connected", peer.id);
    console.log(await peer.getSyncedTime()) // { time: 1674671482107, rtt: 2, offset: 0 }
    peer.send({
        hello: "world"
    });
});
client.on("message", (packet) => {
    console.log("From:", packet.peer.id, "Message:", packet.msg);
});
client.on("disconnected", (peer, reason) => {
    console.log("Disconnected", peer.id, "Reason:", reason);
});

Upcoming Features

Mesh Network
Multiple transports: tcp, udp*, ipc
Client reconnection

* this will require a change in the protocol, as the protocol assumes the packets are sent using a reliable, ordered connection
