Recommended: JavaScript SDK with React Hooks

For new React apps, we recommend the JavaScript SDK with React Hooks (@dynamic-labs-sdk/react-hooks) instead of the legacy React SDK documented here. The JS SDK comes with many benefits such as a much smaller bundle size and other optimizations. Use the React quickstart (JavaScript SDK) to get started.
Available from SDK V3.0+

​
Summary

Used to manually reinitialize the whole SDK at any point in time. It will reset not just the user state (as useRefreshUser does), but the whole SDK state including wallets, the primaryWallet, user state, etc. An example of where this hook can be helpful is if you have multiple separate windows (things like a Chrome extension popup and a Chrome page for the same extension) where Dynamic is active and you want to ensure they are all in sync. While in process, the sdkHasLoaded boolean on useDynamicContext will be false, and once completed, it will be true.

​
Usage

import {
  DynamicContextProvider,
  useReinitialize,
} from '@dynamic-labs/sdk-react-core';

const ReInitButton = () => {
  const reinitialize = useReinitialize();

  return (
    <button onClick={reinitialize}>Reinitialize</button>
  );
}

const App = () => {
  return (
    <DynamicContextProvider>
      <ReInitButton />
    </DynamicContextProvider>
  )
}
