App Description

The Web Crawler is a Node.js CLI application that scrapes https://www.themoviedb.org & http://www.imdb.com. The information gathered is stored in a DB and then visualized. The user can perform different operations over the information, such as: filtering, searching, sorting, updating. The application doesn't use the APIs of IMDB and TMDB. In fact it gets a page url (e.g. https://www.themoviedb.org/movie?page=1 ), parses it with jsdom and using jquery the movies' URLs are gathered. Then the application parses all of the movies' urls again with jsdom. With jquery the necessary data is then gathered and stored in the db. All this is done asynchronously using Promises and Async/Awaits. The data visualization is table structured using columnify.
