<h1>About</h1>
<p>
This app keeps a set of code snippets and programming resources categorized by language/library.
Each snippet or resource can be associated with multiple languages and vice versa.
</p>
<p>Features I plan to add to the backend:</p>
<ul>
<li>A login system</li>
<li>Add a column for snippets to indicate the language the snippet is written in</li>
<li>Search</li>
</ul>
<p>Features I plan to add to the web client:</p>
<ul>
<li>Syntax highlighting via <a href="http://prismjs.com/" target="_blamk">Prism</a></li>
<li>When a single language is selected, show all related snippets and resources</li>
<li>Deep linking</li>
</ul>
<hr>
<h1>Tables</h1>
<p>There are three main tables:</p>
<ul>
<li>language</li>
<li>snippet</li>
<li>resource</li>
</ul>
<p>And three tables used to link these tables together:</p>
<ul>
<li>langLang</li>
<li>langSnippet</li>
<li>langResource</li>
</ul>
<img id="tablesImg" src="tables.png" class="img-fluid rounded my-3 p-2 border">
<p>Each of the three main tables has a corresponding API endpoint (off of the base URL webdev.neilbrommer.com/multiTable/):</p>
<ul>
<li>lang.php</li>
<li>snippet.php</li>
<li>resource.php</li>
</ul>
<hr>
<h1>API</h1>
<p>
Each of the endpoints is off of the base URL of <u>https://webdev.neilbrommer.com/multiTable/</u>.
SSL is required.

<p>Arguments that are <u>underlined</u> are optional.</p>
