Events

The Nostr Provider uses an event model similar to Node.js EventEmitter.

The application can monitor account changes and refresh the local state after the user switches identities:

accountsChanged​

Triggered when the user switches Nostr accounts or the authorization status changes.

window.nostr.on("accountsChanged", (accounts) => {
  // Handle newly exposed accounts, or the case where there are no accounts.
  // "accounts" will always be an array, though it can be empty.
});
window.nostr.off("accountsChanged");

chainChanged (deprecated)​

This event is deprecated. If the old environment still triggers it, re-read the Provider state.

window.nostr.on('chainChanged', (chainId) => {
    // Handle the newly selected chain.
    // Handling chain changes correctly can be a little involved.
    // Unless you have a strong reason not to, reloading the page is the simplest approach.
    window.location.reload();
});
window.nostr.off('chainChanged');
