Shared contract and helpers for the realtime SSE stream

Overview

The framework-agnostic contract for the unified realtime SSE stream — no DOM, no NestJS. It defines the event-type strings, frame shapes, channel definitions, and small registry helpers that derive subscription patterns and the known-types set from a descriptor registry. Producers publish against these shapes and the frontend imports the same definitions to route incoming frames. Dependency-light by design.

When to use it

• Use it when a producer or a frontend needs the shared realtime frame and channel definitions.

Installation

pnpm add @xemahq/realtime-events

Usage

import { subscribedPatternsFromRegistry } from '@xemahq/realtime-events';

const patterns = subscribedPatternsFromRegistry(descriptors);
