The idea behind building a simple travel app is to call and get corresponding information from the TripAdvisor API regarding three important trip-planning categories: flights, hotels, and attractions, and then saving the trip itinerary in a database. The author plans to create an "Explore the World!" web app that will connect to the TripAdvisor API, set up Node, Express, and Handlebars, and render templates for text, images, and colors. Despite initially being denied an API key by TripAdvisor, the author was able to obtain a RapidAPI key and proceed with making calls using this key. The app will have three views: one for displaying a list of attractions when a city is entered into a form on the "home" page. The author plans to code the route that retrieves information from the TripAdvisor API based on the location entered in the form, cleans the data, and passes it through to the "attractions.handlebars" template. Once this basic functionality is implemented, the author will move on to booking hotels and flights through the TripAdvisor API and using more advanced CSS.
