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.

Displaying list elements

In this section, we deal with the first display of the page. Insertion has been seen previously, and modification and deletion are covered in the following sections.

Note

To display the list when the application starts, you must use the created() method or the mounted() method of the component, which are called in each Vue.js component when the component is created.

To retrieve the list of elements, we are going to use an HTTP GET request.

Using Axios with a GET type request (client side)

Here, we are going to make a GET type request with the /list URL to the server. The axios.get("/list") instruction is used to perform this request. We can use this instruction in the created() or mounted() method. Here, we choose to use it in the created() method:

Retrieving list of items, client side (global-app.js file)

import Element from "./element.js";
const GlobalApp = {
  data() {
    return {
