The application is designed to help users quickly donate to any number of charities and nonprofits. It uses a combination of PHP, Vue.js, and Tailwind CSS to build a simple yet effective interface. The backend API is built using the Slim framework and PHP 8.0 or above, while the frontend is built using Vue.js with Tailwind CSS styling. The application retrieves a list of six charities from the backend API and displays their details on the page, including images, descriptions, actions, social media links, and donation links.
