progress web apps

相关技术

1. web app manifest（添加到首屏, 首屏图标与全屏展示，提供类似原生应用的体验）

{
  "short_name": "AirHorner",
  "name": "Kinlan's AirHorner of Infamy",
  "icons": [
    {
      "src": "launcher-icon-4x.png",
      "type": "image/png",
      "sizes": "192x192"
    }
  ],
  "start_url": "index.html?launcher=true"
}

2. service worker（缓存与推送)

为什么不用 appcache Application Cache is a Douchebag

service worker 可以视为可编程的network proxy, 与cacheStorage 结合可以满足 offline cache 的需求

service worker 生命周期: install, waiting, active

缓存策略: cache fallback to network, network fallback to cache, cache then network, race, etc.

缓存更新: 更新 cache key 或者使用特定缓存策略

service worker 支持接收 push 及展示 notifications push-notifications
