IdleFish Double 11 2023: Frontend Engineering Challenges and Solutions
During IdleFish’s 2023 Double 11 promotion, engineers tackled massive traffic spikes by running feature‑flag, launch‑side, and mitmproxy‑based disaster‑recovery rehearsals, boosted performance with increased first‑screen modules, CSS‑only animations, pre‑fetching and offline caching, introduced a PHA container for seamless tab switching, and optimized deep‑link handling for external channels, while planning further SSR and stability automation.
