JavaScript from Frontend to Backend

By: Eric Sarrion

Overview of this book

JavaScript, the most widely used programming language in the world, has numerous libraries and modules and a dizzying array of need-to-know topics. Picking a starting point can be difficult. Enter JavaScript from Frontend to Backend. This concise, practical guide will get you up to speed in next to no time. This book begins with the basics of variables and objects in JavaScript and then moves quickly on to building components on the client-side with Vue.js and a simple list management application. After that, the focus shifts to the server-side and Node.js, where you’ll examine the MVC model and explore the Express module. Once you've got to grips with the server-side and the client-side, the only thing that remains is the database. You’ll discover MongoDB and the Mongoose module. In the final chapter of this fast-paced guide, you'll combine all these pieces to integrate a Vue.js application into a Node.js server, using Express to structure the server code and MongoDB to store the information. By the end of this book, you will have the skills and confidence to successfully implement JavaScript concepts in your own projects and begin your career as a JavaScript developer.

Chapter 4: Advanced Concepts of Vue.js

In this chapter, we look at advanced uses of Vue.js. We will study the handling of events in components, then the assembly of the various components in order to form a whole Vue.js application.

Why is it important to know how to handle events in components?

A Vue.js component is often a set of HTML elements, like building blocks, such as buttons, lists, and input fields. It is therefore essential to know how to manage the interaction of these elements with the possible actions of the user, such as clicking on a button, entering a value in an input field, or selecting an element from a list.

Similarly, why is it important to know how to assemble the components?

A web application brings together many elements, which in the end, will represent the application as a whole. The principle of Vue.js is to break down an application into components, then assemble them to form the complete application. We will have to learn how to divide an application...
