Frontend Coding Interview Test

We recommend (although not required) to use the following languages, libraries, components: TypeScript, React Query or RSC, Tailwind, shadcnUI, Next.js Image component, and zod (for API output validation).

How to use

Clone using the following command:

git clone https://github.com/mmiro-balize/frontend-test.git

Navigate to the frontend-test directory and run the following command:

npm install

To run the project, use the following command:

npm run dev

Requirements

1. Fetch Pokémon Data:

   • Use the Pokémon API endpoint: https://pokeapi.co/api/v2/pokemon to fetch a list of Pokémon.
   • The API returns a JSON object with the following structure:

     {
       count: number; // Total number of Pokémon
       next: string | null; // URL for the next page of results
       previous: string | null; // URL for the previous page of results
       results: {
         name: string;
         url: string;
       }
       []; // List of Pokémon
     }

2. Create Initial Data Table:

   • Render the Pokémon in a data table with a single column:
     • Name: Display the name of the Pokémon.
   • At this stage, only the "Name" column should be populated since this is the only data available after the initial API fetch.

3. Enhance Data Table with Additional Columns:

   • For each Pokémon in the table, use the url provided in the results to fetch additional details from each Pokémon's individual endpoint.
   • • The API returns a JSON object with the following structure:

     {
       id: number;
       sprites: {
         front_default: string;
       } // Image URLs
       types: {
         slot: number;
         type: {
           name: string;
         }
       }
       [];
     }

   • Add two new columns to the data table:
     • Image: Fetch and display each Pokémon's image (sprite).
     • Types: Fetch and display each Pokémon's types.

4. Pagination or Infinite Scroll:

   • Implement either pagination or infinite scrolling to allow fetching and displaying the next set of Pokémon using the next property from the API response.
   • If pagination is chosen, provide controls to navigate between pages.
   • If infinite scrolling is chosen, automatically fetch and display the next set of Pokémon as the user scrolls down.

5. Skeleton Loading State:

   • Render a skeleton data table while the API data is being fetched.
   • Style the skeleton table to match the design of the final data table (e.g. using the same colors, column widths, etc.).
   • The table must cleary indicate that the data is being fetched (e.g. with animated skeleton elements).
