Optimizing Static Resource Loading for Meituan Scan-to-Pay with ThunderJS and Build Service

Meituan’s Scan‑to‑Pay H5 app uses ThunderJS and a dedicated Build Service to deliver character‑level incremental JavaScript updates, switching to Myers’ algorithm, isolating computation in a Mixer service, caching results, and adding timeout recovery, which cut data transfer up to 99%, reduced 90th‑percentile latency from 5.8 s to 90 ms, and raised success rates above 99%.
