Modern JavaScript Applications

By: Narayan Prusty

Overview of this book

Over the years, JavaScript has become vital to the development of a wide range of applications with different architectures. But JS moves lightning fast, and it’s easy to fall behind. Modern JavaScript Applications is designed to get you exploring the latest features of JavaScript and how they can be applied to develop high-quality applications with different architectures. Begin by creating a single page application that builds on the innovative MVC approach using AngularJS, then move forward to develop an enterprise-level application with the microservices architecture using Node to build web services. After that, shift your focus to network programming concepts as you build a real-time web application with websockets. Learn to build responsive, declarative UIs with React and Bootstrap, and see how the performance of web applications can be enhanced using Functional Reactive Programming (FRP). Along the way, explore how the power of JavaScript can be increased multi-fold with high performance techniques. By the end of the book, you’ll be a skilled JavaScript developer with a solid knowledge of the latest JavaScript techniques, tools, and architecture to build modern web apps.

Spacing utility classes


Bootstrap 4 adds a new set of utility classes called spacing utility classes. These classes allow you to quickly add spacing in any direction of an element via margin or padding.

The format of these classes is [margin or padding]-[direction]-[size].

For margin or padding, use the following:

  • m for margin

  • p for padding

For direction, you can use these:

  • a for all

  • t for top

  • r for right

  • l for left

  • b for bottom

  • x for left and right

  • y for top and bottom

You can use these for sizes:

  • 0 for zero

  • 1 for 1rem

  • 2 for 1.5rem

  • 3 for 3rem

Here is an example to demonstrate the spacing utility classes. Place this code at the end of the container element of index.html:

<hr>
<div class="row">
  <div class="col-xs-12 m-t-2">
    <p>
