RTC
===

[](#rtc)

Real-time collaboration websocket transport support using WordPress.com infrastructure.

This package extends Gutenberg's Real-Time Collaboration (RTC) feature with a PingHub WebSocket transport provider, replacing the default HTTP polling with persistent WebSocket connections through the WordPress.com PingHub service.

How to install rtc
------------------

[](#how-to-install-rtc)

### Installation From Git Repo

[](#installation-from-git-repo)

Usage
-----

[](#usage)

Add the package as a dependency in your plugin's `composer.json`:

```
"require": {
    "automattic/jetpack-rtc": "@dev"
}
```

Then initialize it in your plugin:

```
use Automattic\Jetpack\Rtc;

RTC::init();
```

Architecture
------------

[](#architecture)

The package has two main layers:

### PHP (`src/`)

[](#php-src)

- **`RTC`** — Main class. Manages providers, enqueues assets, registers REST routes, and handles the RTC settings.
- **`REST_Pinghub_Token`** — REST endpoint that generates short-lived JWTs for PingHub WebSocket authentication.

### JavaScript (`src/js/`)

[](#javascript-srcjs)

- **`rtc.ts`** — Entry point. Registers the PingHub provider via the `sync.providers` filter.
- **`providers/pinghub/`** — PingHub provider implementation:
    - `pinghub-provider.ts` — Yjs provider (thin shell delegating to the manager).
    - `pinghub-manager.ts` — Per-room sync protocol, awareness, and reconnection logic.
    - `pinghub-bridge.ts` — WebSocket transport layer.
    - `keepalive-worker.ts` — Web Worker for awareness keepalive ticks.
