Cache Storage 条目枚举与容量控制实践

概述合理的缓存容量与清理策略有助于维持性能与新鲜度。本文演示缓存枚举与策略清理。枚举与清理async function listCache(name) { const cache = await caches.open(name); const keys = await cache.keys(); return keys.map(k => k.url); } async function limitCache(name, max = 100) { const cache = await caches.open(name); const keys = await cache.keys(); for (let i = 0; i < Math.max(0, keys.length - max); i++) { await cache.delete(keys[i]); } }
