The browser previously retried every failed shared high-score submission on the 50 ms polling interval. With server-side rate limiting and database load shedding, immediate 429 and 503 responses could create a tight retry loop. Add a bounded exponential delay with jitter, honor Retry-After on transient responses, and reset the delay after a successful submission. Keep the pending revision retryable without allowing overlapping requests. Test Plan: - `node --check tdkpin-rs/web/storage.js` -- passed - `prettier --check tdkpin-rs/web/storage.js` -- passed - Node VM retry timing harness covering Retry-After, backoff, and reset -- passed - `git diff --cached --check` -- passed
TDK Pinball Machine web build
Build and serve the browser version from this directory with:
just web-serve
The game is compiled for wasm32-unknown-unknown and loaded into a fixed
640x460 canvas centered on the black page by index.html. Browser settings and
a fallback copy of the high-score table are saved in localStorage; native
builds continue to use their normal per-user save file.
The page includes the official Macroquad browser loader locally. The WASM
bootstrap is local as well, so the page does not require inline or third-party
JavaScript. The web page must be served over HTTP rather than opened directly
from a file: URL.
For a strict Content Security Policy, allow script-src 'self' 'wasm-unsafe-eval' for the browser's WebAssembly compilation and
connect-src 'self' for the local WASM and optional high-score API requests.
When the same-origin /api/highscores endpoint is available, the browser loads
and submits the shared top-ten table there. The small Axum service and an nginx
proxy example are in highscore-server.
