ws13 — WebSocket API
v1.1.0
Modular, extensible and operations-friendly WebSocket framework for
Node.js. This release focuses on a small, stable core so dependent projects can proceed; extensions (channels, auth, history, events, admin, routing, heartbeat, message-meta,
permessage-deflate) exist as planned work and will be completed and documented in follow-up
releases.
Status: core stable and testable — extensions work in progress (APIs
present in repository; integration examples available in examples/).

✨ Highlights (v1.1.0)
- Small, well-tested core for WebSocket handshake, frame
parsing/serialisation and basic client/server modes. -
createRegistry()— lightweight connection registry
with broadcast and auto-clean. -
attachServer(server, opts)— simple HTTP upgrade
wiring. - Built-in support for
permessage-deflate(RFC 7692)
provided as an optional extension instance. - Client-side reconnect helpers (configurable) and heartbeat
primitives in core. - TypeScript definitions included ('index.d.ts') for IDE support.
- Tests included for core registry and basic behaviour (see
'index.test.js').
Extensions (channels, events, history,
admin, routing,
message-meta, heartbeat) are available as separate modules
in the repo but marked WIP — README below points to that.
📦 Installation
npm:
npm install ws13
yarn:
yarn add ws13
🚀 Quick start —
minimal server
This example uses the core createWebSocket exported from the package.
const http = require('http');
const createWebSocket = require('ws13');
const server = http.createServer();
const { registry } = createWebSocket.attachServer(server, {
onConnect(ws, req) {
ws.send('Welcome');
ws.on('message', (evt) => {
// simple echo
ws.send(`Echo: ${evt.data}`);
});
}
});
server.listen(8080);
Client (Node.js reusing createWebSocket in client mode):
const http = require('http');
const createWebSocket = require('ws13');
const req = http.request({ host: '127.0.0.1', port: 8080, path: '/' });
const ws = createWebSocket({ request: req });
ws.on('open', () => ws.send('hello'));
ws.on('message', (evt) => console.log(evt.data));
Browser clients should use the native WebSocket API (wss:// for TLS).
🧩 Core API (summary)
-
createWebSocket(options): create client or server
WebSocket-like instance - options highlights:
request(IncomingMessage |
ClientRequest),socket,protocol,origin,
heartbeatInterval_ms,extension(or null),autoReconnect,
requestFactory,shouldReconnect,isDebug. - returned object is EventEmitter-like and supports:
send(data),sendPing(data),sendPong(data),
heartbeat(cb),close(code, reason). Properties:readyState,
ip,port,latency_ms,bufferedAmount,
protocol,extensions,url. -
createRegistry(): returns
{ add(ws), delete(ws), broadcast(data), size(), clients:Set } -
registryauto-cleans clients on
close/error. -
attachServer(server, { registry?, onConnect? }):
attaches upgrade handler and returns{ registry }. - Default
permessage-deflateextension is provided
in core (createPermessageDeflate) and can be disabled viacreateWebSocket({ extension: null }).
TypeScript definitions are available at 'index.d.ts' for full shapes
and options.
🧪 Tests
Project ships basic tests for the core. Use test-runner-lite (or
Node directly) to run tests.
Run all tests:
npm test
Run the core test directly:
node ./index.test.js
Example core tests included:
- registry add/delete and automatic cleanup on close/error
- attachServer integration behaviour
- basic createWebSocket attachment helpers
Add more tests as needed; tests live next to core and in each
extension folder when implemented.
🧩 Extension roadmap
(short)
The following extensions exist as separate modules and will be fully
documented and stabilised in subsequent releases.
Current status: prototype/partial implementations present in repo.
-
channels— channel-based pub/sub -
message-meta— typed messages with meta
(wrap/unwrap) -
heartbeat— idle/timeout hooks and monitor
-
history— per-channel replay buffer (last N
messages) -
events— JSON-RPC style event emitter
(ws.onEvent / ws.emitEvent) -
admin— HTTP + WebSocket admin API, CSV/JSON
export, disconnect/latency endpoints, live dashboard -
routing— targeted delivery (sendToUser,
sendToRole, sendToIp) -
auth— authentication and role-based
authorization
If your project relies on a specific extension, tell me which one
and I will prioritise finishing it and publishing a stable interface.
🛠 Operational notes
- Default
heartbeatInterval_msin core is 30s (can
be changed per socket). - When enabling compression, configure
maxDecompressSizeto protect against decompression attacks. - Registry clients are a Set; if you need ordered lists or
sharding, wrap registry accordingly. - The core focuses on correctness of handshake and frame handling
— if you need production tuning (backpressure handling, batching or socket pooling) we can add recommended
patterns.

📌 Contributing &
development
- If you need only the core to unblock dependent projects, use
the provided core export and tests. Extensions will follow; they are useful but not required for core
adoption. - Tell me which extension to stabilise first (
channels,history,events,
auth,adminor
routing) and I’ll prepare stable API docs,
tests, and examples.
