Mastering Immutable.js

By: Adam Boduch

Overview of this book

Immutable.js is a JavaScript library that will improve the robustness and dependability of your larger JavaScript projects. All aspects of the Immutable.js framework are covered in this book, and common JavaScript situations are examined in a hands-on way so that you gain practical experience using Immutable.js that you can apply across your own JavaScript projects. The key to building robust JavaScript applications using immutability is to control how data flows through your application, and how the side-effects of these flows are managed. Many problems that are difficult to pinpoint in large codebases stem from data that’s been mutated where it shouldn’t have been. With immutable data, you rule out an entire class of bugs. Mastering Immutable.js takes a practical, hands-on approach throughout, and shows you the ins and outs of the Immutable.js framework so that you can confidently build successful and dependable JavaScript projects.

Preface

DOM side-effects


In this version of our user interface, the side-effects will interact directly with DOM APIs. First, we'll create the overall HTML structure of the UI. Then we'll implement the application logic.

HTML markup

There are three areas that make up this user interface: the filter fields, the rating slider, and the episode listing. Each of these areas will have initial HTML rendered before any JavaScript runs.

Filter fields

To search through episodes, the user is presented with a text input:

<input placeholder="filter" type="search" autofocus/>

Below the search text input are fields that they can select. These fields represent where the search control is looking:

<ul>
  <li>
    <label>
      Title
      <input type="checkbox" name="title" checked/>
    </label>
  </li>
  <li>
    <label>
      Date
      <input type="checkbox" name="date"/>
    </label>
  </li>
  <li>
    <label>
      Director
     ...
