What is an application customizer?

An SPFx application customizer (a type of SPFx extension) is a component that enables developers to extend and customize the user interface of SharePoint sites by injecting custom scripts or HTML elements. It provides a way to add persistent UI elements, such as headers, footers, or custom notifications, across pages within a site or site collection.

Why is it needed?

The need for an SPFx application customizer arises from the limitations of the standard SharePoint interface, which may not always align with an organization’s branding or functional requirements. By using an application customizer, developers can introduce consistent UI elements, implement custom behaviors, or integrate additional functionality into SharePoint without altering the core platform. This enhances user engagement, branding consistency, and the overall user experience.
