For testing, you have to execute the script named scriptSQL.sql with a MySQL server.
Also, open the script contained in the backend, go to the lines 50 and 51, and fill user and password with your MySQL credentials.
For executing the Back-End, just write in the command-line, within the backend folder, node index.js.
For executing the Front-End, see the instructions of the file README.md contained in the folder films.
