The Neo4j Movies Template is a demo application built using Flask and React.js, showcasing how to build a web app with Neo4j as the graph database. The template includes a classic movie database with nodes for Movie, Person, Genre, and Keyword, connected by relationships. Users can add ratings to movies and view their previous ratings on their user profile or the movie detail page. The application uses the Bolt driver for Neo4j and provides an API documentation. The code is written in Python and includes a detailed explanation of how to use the Bolt driver, serialize data, and implement common features such as authentication, registration, and rating movies.
