Overview of this book

With its latest iteration, the powerful Odoo framework released a wide variety of features for rapid application development. This updated Odoo development cookbook will help you explore the new features in Odoo 14 and learn how to use them to develop Odoo applications from scratch. You'll learn about the new website concepts in Odoo 14 and get a glimpse of Odoo's new web-client framework, the Odoo Web Library (OWL). Once you've completed the installation, you'll begin to explore the Odoo framework with real-world examples. You'll then create a new Odoo module from the ground up and progress to advanced framework concepts. You'll also learn how to modify existing applications, including Point of Sale (POS) applications. This book isn't just limited to backend development; you'll discover advanced JavaScript recipes for creating new views and widgets. As you progress, you'll learn about website development and become a quality Odoo developer by studying performance optimization, debugging, and automated testing. Finally, you'll delve into advanced concepts such as multi-website, In-App Purchasing (IAP),, the IoT Box, and security. By the end of the book, you'll have all the knowledge you need to build impressive Odoo applications and you'll be well versed in development best practices that will come in handy when working with the Odoo framework.

Making OWL components reactive

OWL is a powerful framework and supports auto updates for the UI based on hooks. With update hooks, a component's UI will be automatically updated when the internal state of the component is changed. In this recipe, we will update the message in the component based on user actions.

Getting ready

For this recipe, we will continue using the my_library module from the previous recipe.

How to do it...

In this recipe, we will add arrows around the text in the component. Upon clicking the arrow, we will change the message. Perform the following steps to make the OWL component reactive:

  1. Update the XML template of the component. Add two buttons with an event directive around the text. Also retrieve the message dynamically from the list:
    static template = xml`
        <div class="bg-info text-center p-2">
            <i class="fa fa-arrow-left p-1"
