What is the purpose of ngrx/effects library?
<p>I have failed to find any usefull information about this library or what is the purpose of it.
It seems like <a href="https://github.com/ngrx/effects" rel="noreferrer">ngrx/effects</a> explain this library to developers who already know this concept and gives a bigginer example on how to code.</p>
<p><strong>My questions:</strong></p>
<ol>
<li>What are sources of actions?</li>
<li>What is the purpose of ngrx/effects library;what is the downside of only using ngrx/store?</li>
<li>When it is recommended to be used?</li>
<li>Does it support angular rc 5+? How do we configure it in rc 5+?</li>
</ol>
<p>Thanks!</p>
