React-admin: [RFC] Redirection to login should be done in the authProvider

Created on 4 Mar 2019 · 5Comments · Source: marmelab/react-admin

Problem

If the authProvider delegates login and check to a third-party server (e.g. OAuth), then it should be able to manage the login form URL.

Currently, the login form URL is hardcoded. The only possibility to redirect to an external authentication server is to use window.location in AUTH_LOGOUT, which occurs after a first redirection to '/login' in case of voluntary disconnection. That creates a blinking screen.

extract from the current auth saga:

case USER_CHECK: {
    try {
        yield call(authProvider, AUTH_CHECK, payload);
    } catch (error) {
        yield call(authProvider, AUTH_LOGOUT);
        yield put(
            replace({
                pathname: (error && error.redirectTo) || '/login',
                state: { nextPathname: meta.pathName },
            })
        );
    }
    break;
}
case USER_LOGOUT: {
    yield put(
        push(
            (action.payload && action.payload.redirectTo) ||
                '/login'
        )
    );
    yield call(authProvider, AUTH_LOGOUT);
    break;
}
