ngrx/effects - Actions that are depedent on other actions
<p>When fetching data from an API, I first need to check if I already have a token stored, and if it is still valid. If not, I need to get a new one from the API and wait for the <code>GET_TOKEN_SUCCESS</code> action before I can make the actual data request.</p>

<p>How do I handle this scenario with <code>ngrx/effects</code> without having to write all the logic in one single effect?</p>
