@felixgeelhaar/glossa-sdk

Framework-agnostic HTTP client + in-memory bundle cache + SSE subscription for Glossa. Runs in Node and browsers. ~400 LOC, ~10 KB unpacked, zero non-stdlib deps.

pnpm add @felixgeelhaar/glossa-sdk

Usage

Fetch a bundle

import { createClient } from "@felixgeelhaar/glossa-sdk";

const client = createClient({
  apiUrl: "https://glossa.example.com/api/v1",
  apiKey: "glossa_...",
  project: "brotwerk-site",
});

const bundle = await client.bundle("de");
// → { locale: "de", messages: { "hero.title": "Brotwerk", ... }, etag: "..." }

ETag-aware: the second call sends If-None-Match: <etag> and returns the cached copy on 304 without re-parsing.

Subscribe to live updates

const sub = client.subscribe("de", {
  onUpdate(event) {
    // { type: "translation.updated", key, value, status }
    console.log(event.key, "→", event.value);
  },
  onError(err) {
    console.warn("SSE disconnected:", err);
  },
});

// Later:
sub.close();

Each SSE event surgically patches the in-memory cache for that key — no bundle refetch. Reconnects with exponential backoff on transient errors.

Build-time key sync

await client.scan({
  keys: [
    { key: "hero.title", description: "Landing hero" },
    { key: "hero.cta_primary" },
  ],
});

Used by @felixgeelhaar/glossa-cli to seed keys discovered in source files.
