Add-on Development

Add-on development involves creating extensions, plugins, or modules that enhance the functionality of existing software applications, such as web browsers, content management systems, or productivity tools. These add-ons integrate with host applications through defined APIs to provide custom features, integrations, or user interface improvements. It enables developers to build reusable components that extend core software without modifying its source code.

Also known as: Plugin Development, Extension Development, Module Development, Addon Development, Add-in Development

Why learn Add-on Development?

Developers should learn add-on development to customize and extend popular software platforms like browsers (e.g., Chrome, Firefox), CMSs (e.g., WordPress, Drupal), or IDEs (e.g., Visual Studio Code), allowing for tailored user experiences and integration with third-party services. It is particularly useful for creating tools that automate workflows, add new capabilities, or integrate with external APIs in a modular and maintainable way, often leveraging web technologies like HTML, CSS, and JavaScript.
