Web apps, created with the React JavaScript library, are a great way to present content from the CMS to consumers via the headless server. This section provides general information and a guide to set up and develop a React app with the Apollo framework. Apollo connects to the GraphQL endpoint of a CoreMedia headless server and fetches the data to display a CoreMedia page, for which Apollo fits best. This setup and its structure are a recommendation to get started quickly and efficiently. Of course other frameworks or different approaches are possible.
