Contribution Tracker

In the Charity Finder project you created an app to help you locate a charity worthy of your contributions. Once a contribution has been made the goal of the Contribution Tracker app is to track it so to provide users with a record of all contributions for use in monitoring how funds are being directed and to provide records for financial reporting purposes. For example, for tax reporting.


  • Developers may use Vanilla JS, or a framework of their choice (like React, VueJS, etc.).

  • Developers should not use libraries for calculating and manipulating monetary amounts. All calculation and formatting should be done in the language chosen to develop the application.

  • Developers may use a graphics presentation library or service of their choice, like AMCharts.

  • Developers may choose to have transactions persist across sessions using either files or databases. Sensitive data, like transactions, must not be maintained in local storage. Remember that although you can implement protections it is impossible to totally secure browser applications.

User Stories

  • User can see a Navigation Bar at the top of each page containing the application name and a "hamburger" menu with these option: - Dashboard - Transactions
  • User can see a Footer Bar at the bottom of each page containing an About link

Dashboard Page

  • User can see the Dashboard page when the app is started containing graphical summaries of the following key metrics. The graphical representation for each is left up to the Developer. - Contributions by month for the current year - Total contributions by year - Contribution increase/decrease by year - Average contribution amount by month and year
  • User can return to the Dashboard page, if currently on another page, by clicking on the 'Dashboard' option in the hamburger menu in the Navigation Bar.
