124. How to implement pagination in Front End?

For page number based pagination, the API should be able to return the total number of pages and the number of items per page. As for the Front End implementation, we can create a component for displaying the page numbers and use state to keep track of the current page. We can also add an onClick event handler to each page number button that fetches the data for the corresponding page from the API and updates the UI.

For infinite scroll pagination, the API should be able to return a fixed number of items per request. As for the Front End implementation, we can use a library like React Infinite Scroll or React Intersection Observer to fetch and append more data to the UI as the user scrolls down.

For prev/next style pagination, the API should be able to return the previous and next page numbers. As for the Front End implementation, we can create two buttons for previous and next pages respectively and use an onClick event handler to fetch the data for the corresponding page from the API and update the UI.

Overall, the key is to have a clear API interface that specifies the pagination options and to select the pagination method that best fits the use case of the application.
