Summary

In this chapter, we learned about an SPFx extension called application customizer. We started by understanding what an application customizer is, when it is needed, and what it is used for. Then, we moved on to creating an application customizer using SPFx; we learned how it is rendered and what placeholders are.

After that, we looked at adding a React component to the application customizer by going into the details of what the component does and how it can render simple text.

Once the React component was ready, we updated the service to get filtered items using Microsoft Graph and used it in the component to render products that are low in stock.

In the next chapter, we will look at a field customizer that will give control over rendering a field as per our requirements.
