Users on the MERN VR Game application will be able to open and play any of the VR games from within the application. To enable this, we will add an API on the server that renders the index.html file, which was generated with React 360, as discussed in the previous chapter, Chapter 13, Developing a Web-Based VR Game. This API on the backend will receive a GET request at the following path:
/game/play?id=<game ID>
This path takes a game ID value as a query parameter. The game ID in this URL will be used in the React 360 code, as elaborated on later in the chapter, to fetch the game's details using the load game API. In the following section, we will look at the implementation of the backend API that will handle this GET request to start playing a game when the user clicks on the PLAY GAME button.
