Sweep: Implement a feature to display more countries in `Home.jsx`

On the homepage, only at most 12 countries are shown currently. We need to add a button to load more countries when clicked.

Create a button after the Countries component. Clicking this should load 12 more countries.
Show a loading spinner for 3 seconds before displaying new items. For styling spinner, reference this.

https://github.com/IndieCoderMM/nation-guide/blob/dev/src/pages/Home.jsx#L39

Checklist

src/pages/Home.jsx ✅ Commit 052e070

• Add a new state variable `displayCount` with initial value 12 to keep track of the number of countries currently displayed. • Add a new state variable `loadingMore` with initial value false to keep track of whether the loading spinner should be displayed. • Modify the `countries` variable to slice the first `displayCount` countries instead of always slicing the first 12 countries. • Add a button after the `Countries` component. When this button is clicked, set `loadingMore` to true and use `setTimeout` to set `displayCount` to `displayCount + 12` and `loadingMore` to false after 3 seconds. • Before the `Countries` component, add a conditional rendering to display the loading spinner if `loadingMore` is true. Use the styling from the `Splash.module.css` file for the spinner.

The page in question is a JavaScript file located at https://github.com/IndieCoderMM/nation-guide/blob/dev/src/pages/Home.jsx#L39. The problem at hand is to add a button on the homepage that, when clicked, loads 12 more countries. Additionally, a loading spinner should be displayed for 3 seconds before the new items are shown. The styling for the spinner can be found in the Splash.module.css file at lines 24 to 47.

https://github.com/IndieCoderMM/nation-guide/blob/dev/src/pages/Home.jsx#L39:

The page is a JavaScript file located at src/pages/Home.jsx in the repository IndieCoderMM/nation-guide. The file contains code for the homepage of the application.

The code imports various components such as SearchBox, SortingBox, Countries, PageHolder, and Loading. It also imports functions from the redux/countries and lib/utils files.

The Home component is defined as a functional component. It uses the useState and useEffect hooks from React. It also uses the useSelector and useDispatch hooks from React Redux.

Inside the Home component, there is a state for query and sorter, which are managed using the useState hook. The component also accesses the data and status states from the Redux store using the useSelector hook. The dispatch function is used to dispatch actions to the Redux store.

The useEffect hook is used to fetch all countries when the component mounts or when the status state changes.

The filterAndSortCountries function is called to filter and sort the countries based on the query and sorter states.

If the status is 'loading', a loading spinner is displayed. Otherwise, the filtered and sorted countries are rendered.

The code snippet relevant to the problem is located at line 39. It is suggested to add a button after the Countries component that, when clicked, loads 12 more countries. A loading spinner should be displayed for 3 seconds before the new items are shown. The styling for the spinner can be referenced from the Splash.module.css file in the repository.

Step 2: ⌨️ Coding

src/pages/Home.jsx ✅ Commit 052e070

• Add a new state variable `displayCount` with initial value 12 to keep track of the number of countries currently displayed. • Add a new state variable `loadingMore` with initial value false to keep track of whether the loading spinner should be displayed. • Modify the `countries` variable to slice the first `displayCount` countries instead of always slicing the first 12 countries. • Add a button after the `Countries` component. When this button is clicked, set `loadingMore` to true and use `setTimeout` to set `displayCount` to `displayCount + 12` and `loadingMore` to false after 3 seconds. • Before the `Countries` component, add a conditional rendering to display the loading spinner if `loadingMore` is true. Use the styling from the `Splash.module.css` file for the spinner.
