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.

Removing an element from the list

Finally, we will learn how to remove an element from the list. A DELETE type request will be used for this.

Using Axios with a DELETE type request (client side)

The axios.delete("/list", options) method is used to trigger a DELETE type request on the server. The options parameter must indicate the identifier of the element to be deleted from the collection.

However, unlike the previous axios.get(), axios.put(), and axios.post() calls, the axios.delete("/list", options) call requires that the options parameter be written in the data property (thus written as { data : options }). If you don’t follow this convention, it won’t work.

Here are the instructions for performing a DELETE request with the Axios library:

Deleting an element, client side (global-app.js file)

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