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.

Using Vue.js in an HTML page

To use Vue.js in an HTML page, simply insert the library file into it using the <script> tag.

To check that Vue.js is correctly integrated into the page, let’s display the version number of the library in the Vue.version variable:

Displaying Vue.js version number (index.html file)

<html>
  <head>
    <meta charset="utf-8" />
    <script src="https://unpkg.com/vue@next"></script>
  </head>
  <body>
  </body>
  
  <script>
    alert(`Vue.version = ${Vue.version}`);
  </script>
</html>

If Vue.js is accessible in the page, the Vue object provides access to the version number in its version property as we can see in the following figure:
