Do I need base href='/'?
<p>My understanding according to <a href="https://stackoverflow.com/questions/1889076/is-it-recommended-to-use-the-base-html-tag">this post</a> is that the default <code>base href</code> is <code>'/'</code>. <a href="https://scotch.io/tutorials/routing-angular-2-single-page-apps-with-the-component-router" rel="noreferrer">This scotch tutorial</a> says to include this base href:</p>

<pre><code>&lt;!-- ./index.html  --&gt;
&lt;base href="/"&gt;
</code></pre>

<p>For a basic app, is this strictly necessary, or will browsers assume that <code>'/'</code> is the <code>base href</code> for relative paths anyway?</p>
