Major Changes

• Implement new authExchange API, which removes the need for an authState (i.e. an internal authentication state) and removes getAuth, replacing it with a separate refreshAuth flow.
  The new API requires you to now pass an initializer function. This function receives a utils
  object with utils.mutate and utils.appendHeaders utility methods.
  It must return the configuration object, wrapped in a promise, and this configuration is similar to
  what we had before, if you're migrating to this. Its refreshAuth method is now only called after
  authentication errors occur and not on initialization. Instead, it's now recommended that you write
  your initialization logic in-line.

  authExchange(async utils => {
    let token = localStorage.getItem('token');
    let refreshToken = localStorage.getItem('refreshToken');
    return {
      addAuthToOperation(operation) {
        return utils.appendHeaders(operation, {
          Authorization: `Bearer ${token}`,
        });
      },
      didAuthError(error) {
        return error.graphQLErrors.some(
          e => e.extensions?.code === 'FORBIDDEN'
        );
      },
      async refreshAuth() {
        const result = await utils.mutate(REFRESH, { token });
        if (result.data?.refreshLogin) {
          token = result.data.refreshLogin.token;
          refreshToken = result.data.refreshLogin.refreshToken;
          localStorage.setItem('token', token);
          localStorage.setItem('refreshToken', refreshToken);
        }
      },
    };
  });

Patch Changes

• ⚠️ Fix willAuthError not being called for operations that are waiting on the authentication state to update. This can actually lead to a common issue where operations that came in during the authentication initialization (on startup) will never have willAuthError called on them. This can cause an easy mistake where the initial authentication state is never checked to be valid
