REPL is a web application that allows you to load, search, and view CSV files. Additionally, the user can search the broadband data of a specific county and state. Through built-in commands, the user can upload a CSV file that exists in a “data/” directory, view it in tabular form, and invoke a CSV parser to search for different values within the file through either fully parsing or using a specified column name/number. The broadband data is cached in to avoid multiple API queries. Also, there are extensive error handling cases: messages for unsuccessful file load, value not found, invalid column, searching malformed CSV files, accessing files outside of the protected directory, and more. Finally, the user can use any of the keyboard shortcuts displayed at the bottom of the screen!
