reactjs – 缓存破坏与创建反应应用程序

如果查看index.js文件,可以看到

registerServiceWorker();

从来不想知道它做了什么？如果我们看看它导入的文件,我们可以看到

// In production,we register a service worker to serve assets from local cache.

// This lets the app load faster on subsequent visits in production,and gives
// it offline capabilities. However,it also means that developers (and users)
// will only see deployed updates on the "N+1" visit to a page,since previously
// cached resources are updated in the background.

// To learn more about the benefits of this model,read {URL}
// This link also includes instructions on opting out of this behavior.

如果要删除Web工作者,请不要删除该行.导入取消注册并在您的文件而不是寄存器中调用它.

import { unregister } from './registerServiceWorker';

并告诉电话

unregister()

附：取消注册时,至少需要一次刷新才能使其正常工作

编辑：create-react-app v2现在默认禁用服务工作者
