Usage

Using Context API:

import * as React from 'react';

import { ClearCacheProvider, useClearCacheCtx } from 'react-clear-cache';

const App: React.FC<{}> = () => {
  const { isLatestVersion, emptyCacheStorage } = useClearCacheCtx();
  return (
    <div>
      {!isLatestVersion && (
        <p>
          <a
            href="#"
            onClick={e => {
              e.preventDefault();
              emptyCacheStorage();
            }}
          >
            Update version
          </a>
        </p>
      )}
    </div>
  );
};

ReactDOM.render(
  <ClearCacheProvider duration={5000}>
    <App />
  </ClearCacheProvider>,
  document.getElementById('root')
);

Using render props:

import * as React from 'react';

import ClearCache from 'react-clear-cache';

const App: React.FC<{}> = () => {
  return (
    <div>
      <ClearCache>
        {({ isLatestVersion, emptyCacheStorage }) => (
          <div>
            {!isLatestVersion && (
              <p>
                <a
                  href="#"
                  onClick={e => {
                    e.preventDefault();
                    emptyCacheStorage();
                  }}
                >
                  Update version
                </a>
              </p>
            )}
          </div>
        )}
      </ClearCache>
    </div>
  );
};

export default App;

Using hooks:

import * as React from 'react';

import { useClearCache } from 'react-clear-cache';

const App: React.FC<{}> = () => {
  const { isLatestVersion, emptyCacheStorage } = useClearCache();
  return (
    <div>
      {!isLatestVersion && (
        <p>
          <a
            href="#"
            onClick={e => {
              e.preventDefault();
              emptyCacheStorage();
            }}
          >
            Update version
          </a>
        </p>
      )}
    </div>
