Cold load served ALL static + API responses uncompressed and without cache
headers (~3.7MB over the wire). Delivery only — feature behavior unchanged; no
DB/API-contract/MCP changes.
- apps/client/vite.config.ts: vite-plugin-compression2 emits .br + .gz next to
each built asset (excludes index.html, which the server rewrites at boot with
window.CONFIG — a precompressed copy would go stale). Build emits 187 .br /
175 .gz under dist/assets.
- static.module.ts: @fastify/static `preCompressed: true` serves the .br/.gz
neighbour; `setHeaders` sets `immutable` ONLY for content-hashed /assets/*,
`no-cache` for index.html, and leaves non-hashed files (locales, vad, icons,
manifest) on default etag/last-modified revalidation.
- main.ts: @fastify/compress (threshold 1024) compresses dynamic API JSON + the
rewritten share-SEO HTML. SSE is safe on two counts: `text/event-stream` is not
mime-db-compressible (allowlist skips it) AND the AI-chat stream hijacks the raw
socket (pipeUIMessageStreamToResponse -> res.raw), bypassing the Fastify onSend
lifecycle entirely. No double-compression with preCompressed static (compress
skips already-Content-Encoding'd responses).
- docker-compose.yml: comment recommending an optional HTTP/2 + brotli reverse
proxy (not required).
Deps: apps/client vite-plugin-compression2 2.5.3 (dev), apps/server
@fastify/compress 9.0.0 (matches fastify 5.8.5).
