Introduction

In this chapter, we will look at a variety of jQuery plugins we can use to extend Bootstrap 4. Some of these plugins are not ready for this iteration of the framework, so we will have to make some adjustments to a few of them. Luckily, not all plugins need to be tweaked. Some are ready for Bootstrap 4 out-of-the-box, and due attention has been paid to giving clarifications on the status of each of the plugins used in this chapter regarding the compatibility issues with Bootstrap 4.

Converting checkboxes into Toggles with Bootstrap Toggle plugin

In this recipe, we will use the Bootstrap Toggle plugin, which has not been updated for over a year at the time of writing this book. The plugin is also intended to be used with Bootstrap 3. Luckily, it will not take us a lot of effort to adjust the behavior of this plugin to work with Bootstrap 4.

Getting ready

To begin this recipe, navigate to the Bootstrap Toggle plugin repository, available at https://github.com/minhur/bootstrap-toggle.

Specifically, we need two files from this repository:

• The plugin's CSS, available at https://github.com/minhur/bootstrap-toggle/blob/master/css/bootstrap-toggle.css
• The plugin's JS, available at https://github.com/minhur/bootstrap-toggle/blob/master/js/bootstrap-toggle.js

There is also a Bower installation available for this plugin, by running the bower install bootstrap-toggle code (as described in the official plugin website, at http://www.bootstraptoggle.com).

How to do it…

1. Copy the raw CSS code from the GitHub link at https://raw.githubusercontent.com/minhur/bootstrap-toggle/master/css/bootstrap-toggle.css.
2. Open the currently blank recipe06-01.scss and paste the code copied from step 1.
3. Starting on line 58, add the following code to recipe06-01.scss:

 // added
.toggle-handle {
 background: #ddd;
}

// added
.btn.active.toggle-off {
 box-shadow: inset 0 3px 5px rgba(0,0,0,.125);
 color: #333;
 background-color: #e6e6e6;
 border-color: #adadad;
} 

4. Open the currently empty file titled recipe06-01.ejs, which can be found inside the app folder, and paste the following code:

 <div class="container">

 <div class="mt-5">
 <h1><%- title %></h1>
 <p><a href="https://v4-alpha.getbootstrap.com/components/alerts/" target="_blank">Link to bootstrap alerts docs</a></p>
 
</div><!-- /.container --> 

<div class="col-12 col-md-5">

<div class="checkbox">
 <label>
 <input type="checkbox" data-toggle="toggle">
 Option one is enabled
 </label>
</div>
<div class="checkbox disabled">
 <label>
 <input type="checkbox" disabled data-toggle="toggle">
 Option two is disabled
 </label>
</div>

 <div class="form-check mb-2 mr-sm-2 mb-sm-0">
 <label class="form-check-label">
 <input class="form-check-input" type="checkbox"> Remember me
 </label>
 </div>

</div> 

5. Add the following code to main.scss:

 @import "./bower_components/bootstrap/scss/bootstrap.scss";
@import "./bower_components/bootstrap/scss/_mixins.scss";
@import "./bower_components/font-awesome/scss/font-awesome.scss";
@import "./bower_components/hover/scss/hover.scss";
// @import "./bower_components/bootstrap-toggle/css/bootstrap-toggle.css";
 
 @import "recipe06-01.scss"; 

6. In app/partial/_js.ejs, on line 9, insert the following GitHub CDN link:

 <script src="https://gitcdn.github.io/bootstrap-toggle/2.2.2/js/bootstrap-toggle.min.js"></script> 

7. Run the grunt and harp server commands in separate Bash windows, and preview the result in the browser at localhost:9000/recipe06-01.

How it works…

We used an outdated plugin that was built for Bootstrap 3. However, many of these plugins require just a few simple tweaks to make them work on frontend projects other than Bootstrap 3. In the case of using the plugin with Bootstrap 4, we achieved the desired effect with a few changes to our CSS and HTML, as can be seen in recipe06-01.scss and recipe06-01.ejs. Finally, we referenced the jQuery plugin via GitHub CDN.

Onboarding users with Shepherd

Onboarding is a way to show first-time visitors to your website how to use your site and to showcase its features. It is a great way to get people introduced to what your site offers in a step-by-step fashion.

In this recipe, we will look at using the Shepherd plugin to onboard users. It is available from http://github.hubspot.com/shepherd/docs/welcome/. The official repository is available at https://github.com/HubSpot/shepherd.

Getting ready

To get ready, simply read through the documentation at GitHub. Also, look at the official website for an example of what is possible with this plugin.

How to do it…

1. Open app/partial/_js.ejs and add the following code:

 <%- partial("_recipe-06-02-js") %> 

2. Open app/recipe06-02.ejs and paste this code:

 <div class="container">
<div class="mt-5">
 <h1><%- title %>...
