In this chapter, we implemented all the functionalities for our app. We started with fetching the cars from the backend and showing these in React Table, which provides paging, sorting, and filtering features. Then we implemented the delete functionality and used the toast component to give feedback to the user. The add functionality was implemented using the React Skylight modal-form component. In the edit functionality, we utilized the React Table feature that makes tables editable. Finally, we implemented the ability to export data to a CSV file. In the next chapter, we will start to polish our user interface using the Material UI component library. In the next chapter, we are styling our frontend using React Material-UI component library.
