Additional Info

This project is bootstrapped with Nextjs. I want to make sure both the frontend and backend run on the same server, since Nextjs has the capacity for a full-stack app, I decided to go with it.

Accessible Layout

The Current Layout transactions divs are tabbable and the filter options.

Challenges

One of the challenges I faced is formating the backend end data such that the frontend can show them grouped by the same date they occur. I solved this by

• Mapping through the data and giving data on the same date a common date
• Group the data by the common date
• Put data with the same date in an array with the key date and data

code location - /utils.ts function name - normalizedTxn

Additional Features

• Select Element For Filtering: The Status and Type buttons can be substituted with a select element, such that when a user clicks on Status the select options open with pending, success and failed options, a user clicks on an option the select element returns to its normal state, the search operation occurs with the selected option. Same for Type
• Pagination: This application can be approved by adding pagination to the list of data to improve UX experience.
• Custom Page Size: Provide a UI for users to customize the page size of the data returning from the backend
