I'm having some real trouble trying to get my sidebar/navigation content (using Bootstrap) to show (be expanded) by default on desktop and closed by default on mobile and have the icon showing only on mobile. I cannot seem to get this to work.

<nav class="menu menu-open" id="theMenu">
      <div class="menu-wrap">
        <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarResponsive" aria-controls="navbarResponsive" aria-expanded="false" aria-label="Toggle navigation">
          <i class="fa fa-bars menu-close d-lg-none" id="menu-toggle"></i>
            </button>
          <div id="menu-logo">
            <img src="Final_Logo.png" width="210" height="214" alt="">
          </div>
          <div id="navbarToggleExternalContent">
          <ul id="main-menu">
              <a href="#">Home</a>
              <a href="#">About</a>
              <a href="#">Writing</a>
              <a href="#">Events</a>
              <a href="#">Speaking</a>
              <a href="#">Music</a>
          </ul>
          <ul id="social-icons">
              <li class="facebook"><a href="#"><i class="fab fa-facebook fa-2x"></i></a></li>
              <li class="twitter"><a href="#"><i class="fab fa-twitter fa-2x"></i></a></li>
              <li class="instagram"><a href="#"><i class="fab fa-instagram fa-2x"></i></a></li>
          </ul>
        </div>
      </div>
  </nav>

I have tried using this javascript code, but to no avail:

 $('.menu-close').on('click', function(){
    $('#menuToggle').toggleClass('active');
    $('body').toggleClass('body-push-toright');
    $('#theMenu').toggleClass('menu-open');
    alert("Test");
    });

It looks like this has been answered here: https://stackoverflow.com/a/36289507/378779 Basically, add one of the navbar-expand-* classes to your <nav>, e.g.:

<nav class="menu menu-open navbar-expand-md" id="theMenu">

First just a couple points:

1. You said sidebar, but your markup doesn't really look like a sidebar to me, it looks like a responsive topnav. I'll try to make sense of it as best I can, and I will demonstrate a working sidebar as well, in case that is what you really do want.

2. Your menu items are in a <ul> (unordered list) without any <li> (list items). The bootsrap js/css probably needs the <li>s in order to function correctly. Technically a <ul> without any <li> is valid html, but the only content allowed in a <ul> are <li>s so anchors (or anything else) inside a <ul> must be contained within <li>s to be valid.

3. I'm not sure what exactly you are trying to do with the social icons so I just adjusted them slightly in a way that seems sensible.

4. I added overflow-y: scroll; on the <html> element so that when you open the menu on a small screen it won't cause shifting if a scrollbar gets added. May not be needed depending on your site design and content layout.

So lets start with a very basic responsive menu.

html {
  overflow-y: scroll;
}
.social {
  padding: 4px 8px;
}

</nav>

Okay, that looks okay, but you had an image in the menu. So I'll put an image in the menu and give it a little css to style it. Then with the image, we'll need a little extra CSS to position menu elements nicely:

1. Position the hamburger button so it sits on the bottom of the navbar. I'll use the 200px of the picture and substract a few rem. You could change the top: calc(100px - 1rem); to top: 1rem; to put the hamburger on top, or bottom: 1rem; if you wanted the hamburger to stick to the bottom of the nav even when opened. Or just delete that whole rule to use the bootstrap default which puts the hamburger in the vertical middle.

2. Position the menu items to also rest on the bottom of the menu bar when not collapsed.

3. position the social icons on the bottom also but push them over to the right hand side.

4. Numbers 2 & 3 above should only apply above the medium breakpoint when the menu is not collapsed so I'll put them in a media query to target over 768px (bootstrap's medium breakpoint). This could also be done with bootstraps sass breakpoint mixins, but we'll just use plain css here. You can see the positioning of these elements within the @media query rule in the css, where you could change it to push them to the top of the bar. Or just remove those rules to revert to bootstrap defaults, which vertically centers menu elements, and puts the social icons beneath them. You could also put the social icons into <li> elements within the menu <ul> if you just wanted the icons to fall right into the menu like the other menu items.

Okay, but you said it was a sidebar. I'm not that familiar with bootstrap, but I gather that neither v3 nor v4 provide a sidebar nav by default. Several bootstrap sidebar tutorials can be found here. I have simply used the most basic version from the tutorials linked above to create an example here.

Collapsible Sidebar

$(document).ready(function () {

    $('#sidebarCollapse').on('click', function () {
        $('#sidebar').toggleClass('active');
    });

});

I have created an example for you, based on the bs4 documentation regarding external content.

<div class="pos-f-t">
  <div class="collapse" id="navbarToggleExternalContent">
    <div class="bg-dark p-4">
      <h5 class="text-white h4">Collapsed content</h5>
      <span class="text-muted">Toggleable via the navbar brand.</span>
    </div>
  </div>
  <nav class="navbar navbar-dark bg-dark navbar-expand-lg">
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarToggleExternalContent" aria-controls="navbarToggleExternalContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>
  </nav>
</div>

Within this example the code collapse from the top - instead of the right. Actually I am on leave and wil try to complete the example to fit your needs.

Additional JavaScript:

var externalContent = $('#navbarToggleExternalContent'),
    execOnResize = function(){
// also the next line was only for use in jsfiddle
// in the real world you need to use window.outerWidth
// 992 pixel is the width of breakpoint corresponding to the class "navbar-expand-lg". Feel free to adapt it to fit your needs.
    if(window.innerWidth >= 992){
        externalContent.addClass('show');
    }else{
        externalContent.removeClass('show');
    }
};
// the next line was only addded for jsfiddle       
execOnResize();

window.onresize = function(event) {
    execOnResize();
};

window.addEventListener('load', function() {
    execOnResize();
})

I have also created a fiddle fiddle To see it in action, please resize the inner window in jsfiddle

Your current Javascript code will always run, regardless of the device. What you need is a way to check if the device is a computer or a mobile phone.

One way would be to use the browser's UserAgent:

$('.menu-close').on('click', function(){
    if(navigator.userAgent.match(/(iPod|iPhone|iPad|Android)/)) {
        //mobile
        $('#menuToggle').toggleClass('active');
        $('body').toggleClass('body-push-toright');
        $('#theMenu').toggleClass('menu-open');
        alert("Test");
    }
});

Or, you could simply rely on the window's width (but small desktop windows will be treated like the mobile version):

if(window.innerWidth <= 767) { // a certain threshold value, in pixels
    //mobile
    //do something
}
