리액트 앱 배포시 cache 안남게하기

아래와 같이 unregister를 해주면 serviceworker가 작동하지 않아 캐시가 남지 않는다.

This is probably because of your web worker.

If you look into your index.js file you can see

registerServiceWorker();

Never wondered what it did? If we take a look at the file it got imported from we can see

// 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.

If you want to delete the web worker, don't just delete the line. Import unregister and call it in your file instead of the register.

import { unregister } from './registerServiceWorker';

and tell call

unregister()

P.S. When you unregister, it will take at least one refresh to make it work
