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.

Building the app with Express

Let’s start by creating the application with Express. To do this, type the express list command, which creates the application named list. This application will be accessible using the URL http://localhost:3000, as seen in Chapter 7, Using Express with Node.js.

Let’s type the express list command in the current directory:

Figure 9.7 – Creating the application list with Express

The server is started by typing the indicated commands, namely: cd list, npm install, followed by npm start.

The application is started by typing the URL http://localhost:3000 in the browser.

We display the basic application created as standard by Express (see Figure 9.8).

If an error occurs while loading the Express modules, you can type the npm link express command in order to locate the Express module within the application. And if an error occurs while loading the mongoose module, you can type the npm link mongoose command...
